- -## Overview - -Creating an environment involves five main steps: -1. Define your models (Action, Observation, State) -2. Implement the environment APIs: step, reset, state -3. Create the FastAPI server -4. Build a Docker image and push it to a public docker repo for community to access it -5. Subclass HTTPEnvclient and implement the parsing methods for result and state. - -## Step-by-Step Guide - -### 1. Define Models - -Create your action, observation, and state models using Python dataclasses: - -```python -# models.py -from dataclasses import dataclass -from core.env_server import Action, Observation, State - -@dataclass -class MyAction(Action): - """Your custom action.""" - command: str - parameters: dict - -@dataclass -class MyObservation(Observation): - """Your custom observation.""" - result: str - success: bool - -@dataclass -class MyState(State): - """Custom state fields.""" - custom_field: int = 0 -``` - -### 2. Implement Environment - -Implement the three core methods: `reset()`, `step()`, and `state`: - -```python -# server/my_environment.py -import uuid -from core.env_server import Environment -from ..models import MyAction, MyObservation, MyState - -class MyEnvironment(Environment): - def __init__(self): - super().__init__() - self._state = MyState() - - def reset(self) -> MyObservation: - self._state = MyState(episode_id=str(uuid.uuid4())) - return MyObservation(result="Ready", success=True) - - def step(self, action: MyAction) -> MyObservation: - # Implement your logic here - self._state.step_count += 1 - result = self._execute_command(action.command) - return MyObservation(result=result, success=True) - - @property - def state(self) -> MyState: - return self._state -``` - -### 3. Create FastAPI Server - -Use the `create_fastapi_app` helper to create your HTTP server: - -```python -# server/app.py -from core.env_server import create_fastapi_app -from ..models import MyAction, MyObservation -from .my_environment import MyEnvironment - -env = MyEnvironment() -app = create_fastapi_app(env, MyAction, MyObservation) -``` - -### 4. Define Dependencies - -**For Python-only dependencies (most common case):** - -Create `src/envs/my_env/server/requirements.txt`: -```txt -your-package>=1.0.0 -another-package -``` - -**For complex setup (optional, only if needed):** - -If you need additional setup beyond pip install, create `src/envs/my_env/server/install_deps.sh`: -```bash -#!/bin/bash -set -e - -# Install Python dependencies -pip install --no-cache-dir -r /tmp/requirements.txt - -# Additional setup commands (only if needed) -mkdir -p /some/directory -# ... other setup steps -``` - -### 5. Create Dockerfile - -Build your Docker image from the openenv-base. Place this at `src/envs/my_env/server/Dockerfile`: - -**Simple case (just requirements.txt):** -```dockerfile -# Accept base image as build argument for CI/CD flexibility -ARG BASE_IMAGE=openenv-base:latest -FROM ${BASE_IMAGE} - -# Install dependencies -COPY src/envs/my_env/server/requirements.txt /tmp/requirements.txt -RUN pip install --no-cache-dir -r /tmp/requirements.txt && rm /tmp/requirements.txt - -# Copy environment code -COPY src/core/ /app/src/core/ -COPY src/envs/my_env/ /app/src/envs/my_env/ - -# Health check -HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \ - CMD curl -f http://localhost:8000/health || exit 1 - -# Run server -CMD ["uvicorn", "envs.my_env.server.app:app", "--host", "0.0.0.0", "--port", "8000"] -``` - -**Complex case (requirements.txt + install_deps.sh):** -```dockerfile -ARG BASE_IMAGE=openenv-base:latest -FROM ${BASE_IMAGE} - -# Install dependencies and run setup -COPY src/envs/my_env/server/requirements.txt /tmp/requirements.txt -COPY src/envs/my_env/server/install_deps.sh /tmp/install_deps.sh -RUN chmod +x /tmp/install_deps.sh && \ - /tmp/install_deps.sh && \ - rm /tmp/install_deps.sh /tmp/requirements.txt - -# Copy environment code -COPY src/core/ /app/src/core/ -COPY src/envs/my_env/ /app/src/envs/my_env/ - -# Health check -HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \ - CMD curl -f http://localhost:8000/health || exit 1 - -# Run server -CMD ["uvicorn", "envs.my_env.server.app:app", "--host", "0.0.0.0", "--port", "8000"] -``` - -### 5. Update GitHub Actions Workflow - -**Important**: To enable automatic Docker image builds on GitHub, add your environment to the workflow matrix. - -Edit `.github/workflows/docker-build.yml` and add your environment to the matrix: - -```yaml -strategy: - matrix: - image: - - name: echo-env - dockerfile: src/envs/echo_env/server/Dockerfile - - name: chat-env - dockerfile: src/envs/chat_env/server/Dockerfile - - name: coding-env - dockerfile: src/envs/coding_env/server/Dockerfile - - name: my-env # Add your environment here - dockerfile: src/envs/my_env/server/Dockerfile -``` - -Once added, every push to `main` will automatically: -- Build your Docker image -- Push it to GitHub Container Registry as `ghcr.io/YOUR_USERNAME/openenv-my-env:latest` - -### 6. Implement Client - -Create a client that extends `HTTPEnvClient`: - -```python -# client.py -from core.http_env_client import HTTPEnvClient -from core.types import StepResult -from .models import MyAction, MyObservation, MyState - -class MyEnv(HTTPEnvClient[MyAction, MyObservation]): - def _step_payload(self, action: MyAction) -> dict: - return {"command": action.command, "parameters": action.parameters} - - def _parse_result(self, payload: dict) -> StepResult[MyObservation]: - obs = MyObservation(**payload["observation"]) - return StepResult( - observation=obs, - reward=payload.get("reward"), - done=payload.get("done", False), - ) - - def _parse_state(self, payload: dict) -> MyState: - return MyState(**payload) -``` - -## Building and Using Your Environment - -### Build Docker Images - -```bash -# First, build the base image (if not already built) -docker build -t openenv-base:latest -f src/core/containers/images/Dockerfile . - -# Then build your environment image -docker build -t my-env:latest -f src/envs/my_env/server/Dockerfile . -``` - -### Use Your Environment - -```python -from envs.my_env import MyAction, MyEnv - -# Create environment from Docker image -client = MyEnv.from_docker_image("my-env:latest") - -# Reset -result = client.reset() -print(result.observation.result) # "Ready" - -# Execute actions -result = client.step(MyAction(command="test", parameters={})) -print(result.observation.result) -print(result.observation.success) - -# Get state -state = client.state() -print(state.episode_id) -print(state.step_count) - -# Cleanup -client.close() -``` - -## Project Structure - -Organize your environment following this structure: - -``` -src/envs/my_env/ -├── __init__.py # Export MyAction, MyObservation, MyState, MyEnv -├── models.py # Action, Observation, State definitions -├── client.py # MyEnv client implementation -├── README.md # Environment documentation -└── server/ - ├── __init__.py - ├── my_environment.py # Environment logic - ├── app.py # FastAPI application - └── Dockerfile # Docker image definition -``` - -## Example Environments - -Study these examples to see the patterns in action: - -### Echo Environment -Location: `src/envs/echo_env/` - -A minimal environment that echoes messages back. Great for: -- Learning the basics -- Testing infrastructure -- Reference implementation - -See: [`echo_env/README.md`](echo_env/README.md) - -### Coding Environment -Location: `src/envs/coding_env/` - -Executes Python code in a sandboxed environment. Demonstrates: -- Complex environment logic -- Error handling -- External tool integration (smolagents) - -See: [`coding_env/README.md`](coding_env/README.md) - -## Best Practices - -### 1. Type Safety -Always use typed dataclasses for actions, observations, and state: -```python -@dataclass -class MyAction(Action): - command: str # Use explicit types - count: int = 0 # Provide defaults when appropriate -``` - -### 2. Error Handling -Handle errors gracefully in your environment: -```python -def step(self, action: MyAction) -> MyObservation: - try: - result = self._process(action) - return MyObservation(result=result, success=True) - except Exception as e: - return MyObservation(result="", success=False, error=str(e)) -``` - -### 3. State Management -Track all relevant episode state: -```python -@dataclass -class MyState(State): - # Add custom fields - accumulated_reward: float = 0.0 - last_action: str = "" -``` - -### 4. Documentation -Provide comprehensive README for your environment: -- Overview and purpose -- Quick start example -- Action/Observation specifications -- Build instructions -- Usage examples - -### 5. Testing -Test your environment before containerization: -```python -# test_my_environment.py -from envs.my_env.server.my_environment import MyEnvironment -from envs.my_env.models import MyAction - -def test_environment(): - env = MyEnvironment() - - # Test reset - obs = env.reset() - assert obs.success - - # Test step - action = MyAction(command="test", parameters={}) - obs = env.step(action) - assert obs.success - - # Test state - assert env.state.step_count == 1 -``` - -## Advanced Topics - -### Custom Transforms -Apply transformations to observations: - -```python -from core.env_server import Transform - -class MyTransform(Transform): - def __call__(self, observation: Observation) -> Observation: - # Transform observation - return modified_observation - -# Use in environment -env = MyEnvironment(transform=MyTransform()) -``` - -### Additional Dependencies -Install environment-specific packages in Dockerfile: - -```dockerfile -FROM openenv-base:latest - -# Install specific versions -RUN pip install --no-cache-dir \ - numpy==1.24.0 \ - pandas==2.0.0 \ - your-custom-package==1.0.0 -``` diff --git a/src/envs/atari_env/README.md b/src/envs/atari_env/README.md deleted file mode 100644 index d942f2647..000000000 --- a/src/envs/atari_env/README.md +++ /dev/null @@ -1,396 +0,0 @@ ---- -title: Atari Environment Server -emoji: 🕹️ -colorFrom: '#FF6200' -colorTo: '#D4151B' -sdk: docker -pinned: false -app_port: 8000 -base_path: /web -tags: - - openenv ---- - -# Atari Environment - -Integration of Atari 2600 games with the OpenEnv framework via the Arcade Learning Environment (ALE).

Each task is a simple webpage with a clear objective. Fast resets, randomized variations, dense rewards. Perfect for learning basic web navigation skills. **No external setup needed** - tasks run in isolated browser sessions. - -- **WebArena (Evaluation)**: 812 tasks on real websites (e-commerce, forums, GitLab, Wikipedia). Tasks like "find the cheapest laptop and add to cart" or "create a merge request for bug #123". Multistep, requires reasoning, sparse rewards. Tests if your agent can handle actual websites. **Requires running 7 backend services** (shopping site, GitLab instance, etc.). - -- **VisualWebArena**: Similar to WebArena but requires visual understanding - agents need to interpret images, identify UI elements visually, handle multimodal content. - -- **WorkArena**: Enterprise software tasks (CRM, project management, business workflows).

This environment is designed to work directly with language models and provides a minimal, flexible foundation for conversation-based RL training. - -## Overview - -ChatEnvironment is a lightweight environment that: -- Manages conversation history in Huggingface chat format -- Handles tokenization internally using any compatible tokenizer -- Stores both messages and tokens for efficient model interaction -- Provides a clean interface for building chat-based RL agents - -ChatEnvironment can be used in **two ways**: -1. **Direct usage**: Import and use ChatEnvironment directly in your Python code (best for local development) -2. **HTTP client**: Use ChatEnv client to connect to a ChatEnvironment server (best for distributed/containerized deployments) - -## Quick Start - -### Option 1: Direct Usage (Local) - -```python -from transformers import AutoTokenizer -from envs.chat_env import ChatAction, ChatObservation -from envs.chat_env.server import ChatEnvironment -from core.env_server import Message - -# Initialize with a tokenizer and optional system prompt -tokenizer = AutoTokenizer.from_pretrained("gpt2") -env = ChatEnvironment( - tokenizer=tokenizer, - system_prompt="You are a helpful assistant.", - system_role="system" -) - -# Reset the environment -obs = env.reset() -print(f"Messages: {obs.messages}") -print(f"Tokens shape: {obs.tokens.shape}") - -# Create an action from a message -user_message: Message = {"role": "user", "content": "Hello!"} -action = env.message_to_action(user_message) - -# Step the environment -obs = env.step(action) -print(f"Updated messages: {obs.messages}") -print(f"Updated tokens shape: {obs.tokens.shape}") -``` - -### Option 2: HTTP Client (Distributed) - -```python -from transformers import AutoTokenizer -from envs.chat_env import ChatEnv, ChatAction -import torch - -# Create environment from Docker image -client = ChatEnv.from_docker_image("chat-env:latest") - -# Or connect to existing server -# client = ChatEnv(base_url="http://localhost:8000") - -# Reset -result = client.reset() -print(f"Initial messages: {result.observation.messages}") - -# Send an action with tokens -tokenizer = AutoTokenizer.from_pretrained("gpt2") -message = {"role": "user", "content": "Hello!"} -action = client.message_to_action(message, tokenizer) - -result = client.step(action) -print(f"Messages: {result.observation.messages}") -print(f"Reward: {result.reward}") - -# Cleanup -client.close() -``` - -### Building the Docker Image - -Before using the HTTP client, build the Docker image: - -```bash -# From project root -docker build -t chat-env:latest -f src/envs/chat_env/server/Dockerfile . - -# Optionally specify a different tokenizer -docker build -t chat-env:latest \ - --build-arg TOKENIZER_NAME=meta-llama/Llama-2-7b-chat-hf \ - -f src/envs/chat_env/server/Dockerfile . -``` - -## Architecture - -### Data Models - -#### ChatAction -Actions contain only tokens (PyTorch tensors) that interface directly with models: -```python -@dataclass -class ChatAction(Action): - tokens: torch.Tensor # Required, cannot be empty -``` - -#### ChatObservation -Observations contain both the message history and flattened tokens: -```python -@dataclass -class ChatObservation(Observation): - messages: list[Message] # List of {"role": str, "content": str} - tokens: torch.Tensor # Flattened tensor of all conversation tokens - # Inherited: done, reward, metadata -``` - -#### ChatState -Internal state tracking message and token history: -```python -@dataclass -class ChatState(State): - history_messages: list[Message] - history_tokens: list[torch.Tensor] - # Inherited: episode_id, step_count -``` - -### Key Methods - -#### `reset() -> ChatObservation` -Resets the environment to initial state with optional system prompt. - -#### `step(action: ChatAction) -> ChatObservation` -Takes an action (tokens), decodes to text, adds to history, returns updated observation. - -#### `message_to_action(message: Message) -> ChatAction` -Convenience method to convert a message dict to a tokenized ChatAction. - -## Usage Patterns - -### Basic Conversation - -```python -from transformers import AutoTokenizer -from envs.chat_env.server import ChatEnvironment -from core.env_server import Message - -tokenizer = AutoTokenizer.from_pretrained("gpt2") -env = ChatEnvironment(tokenizer=tokenizer) - -# Reset -obs = env.reset() - -# User turn -user_msg: Message = {"role": "user", "content": "What is 2+2?"} -action = env.message_to_action(user_msg) -obs = env.step(action) - -# Assistant turn -assistant_msg: Message = {"role": "assistant", "content": "2+2 equals 4."} -action = env.message_to_action(assistant_msg) -obs = env.step(action) - -# Access conversation history -print(f"Full conversation: {obs.messages}") -print(f"All tokens: {obs.tokens}") -``` - -### With Transforms - -You can add transforms to compute rewards or modify observations: - -```python -from core.env_server import Transform, Observation - -class LengthRewardTransform(Transform): - """Reward based on response length.""" - - def __call__(self, observation: Observation) -> Observation: - if hasattr(observation, 'messages') and observation.messages: - last_message = observation.messages[-1] - observation.reward = len(last_message['content']) * 0.1 - return observation - -env = ChatEnvironment( - tokenizer=tokenizer, - transform=LengthRewardTransform() -) -``` - -### Direct Token Usage - -If you're generating tokens from a model, you can create actions directly: - -```python -import torch -from envs.chat_env import ChatAction - -# Assume you have tokens from your model -generated_tokens = torch.tensor([[1, 2, 3, 4, 5]]) - -# Create action directly -action = ChatAction(tokens=generated_tokens) - -# Step environment -obs = env.step(action) -``` - -## Design Philosophy - -ChatEnvironment is intentionally minimal and flexible: - -1. **No HTTP overhead**: Works directly with Python objects and tensors -2. **Tokenizer ownership**: Environment handles tokenization consistently -3. **Dual representation**: Maintains both human-readable messages and model-ready tokens -4. **Transform support**: Extensible reward computation and observation modification -5. **Type-safe**: Uses typed Messages compatible with Huggingface format - -## Integration with Models - -ChatEnvironment pairs naturally with language models: - -```python -# Pseudo-code for RL training loop -model = YourLanguageModel() -env = ChatEnvironment(tokenizer=model.tokenizer) - -for episode in range(num_episodes): - obs = env.reset() - - while not obs.done: - # Model generates response tokens - action_tokens = model.generate(obs.tokens) - action = ChatAction(tokens=action_tokens) - - # Step environment - obs = env.step(action) - - # Use obs.reward for RL updates - model.update(obs.reward) -``` - -## Project Structure - -``` -chat_env/ -├── __init__.py # Module exports (ChatEnv, ChatAction, etc.) -├── README.md # This file -├── client.py # ChatEnv HTTP client -├── models.py # ChatAction, ChatObservation, ChatState -└── server/ -

-## Overview - -The `DIPGSafetyEnv` is a custom environment built on the OpenEnv framework for Reinforcement Learning research in high-stakes AI safety. It was developed to address a critical use case: ensuring the reliability and safety of a Large Language Model (LLM) agent operating in the medical domain of **Diffuse Intrinsic Pontine Glioma (DIPG)**, a universally fatal pediatric brain tumor. - -In this context, an AI's failure is not an option. The environment's primary purpose is to train and rigorously evaluate an agent's ability to: -1. Base its answers *only* on the verified clinical context provided. -2. Correctly identify and report conflicting information from different sources. -3. Safely abstain from answering when the context is insufficient. -4. Strictly avoid hallucinating facts or providing unsafe, unsupported information. - -## Features - -The environment server contains a suite of safety-critical reward functions that score an agent's response based on the following behaviors: - -* **Conflict Identification:** Rewards the agent for correctly stating that provided sources are contradictory. -* **Knowledge Abstention:** Rewards the agent for recognizing when a question cannot be answered from the given text and explicitly saying so. -* **Format Adherence:** Positively or negatively scores the response based on its adherence to a required structured output format. -* **Hallucination Penalty:** Heavily penalizes the agent for generating any information that is not supported by the provided context. - -## Getting Started: How to Use the Environment - -The `DIPGSafetyEnv` follows a standard client-server model. - -### 1. Running the Server - -The server requires the custom synthetic dataset (`harmonic_reasoner_dataset_structured.jsonl`). You can download it from [here](https://huggingface.co/datasets/dvitel/Harmonic-Reasoner/resolve/main/harmonic_reasoner_dataset_structured.jsonl). - -The recommended way to run the server is with `gunicorn` for better performance and stability. - -```bash -# Install gunicorn -pip install gunicorn - -# Set the dataset path environment variable -export DIPG_DATASET_PATH=/path/to/your/harmonic_reasoner_dataset_structured.jsonl - -# Run the server -PYTHONPATH=./src gunicorn -w 4 -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8009 envs.dipg_safety_env.server.app:app -``` - -### 2. Interacting from the Client - -Once the server is running, an agent can interact with it using the `DIPGSafetyEnv` client. - -```python -from envs.dipg_safety_env.client import DIPGSafetyEnv -from envs.dipg_safety_env.models import DIPGAction - -# Connect to the running server -env = DIPGSafetyEnv(base_url="http://localhost:8009", timeout=60) - -# Start a new episode and get the first challenge -# The 'obs' object will contain a medical context and a question. -obs = env.reset() -print(f"Question: {obs.observation.question}") - -# The agent processes the observation and generates a response -agent_response_text = "Based on the provided context, the information is conflicting." - -# Send the response (as an Action) to the environment to be scored -action = DIPGAction(llm_response=agent_response_text) -result = env.step(action) - -# The result contains the reward and a flag indicating the episode is done -print(f"Reward: {result.reward}") -print(f"Done: {result.done}") -``` - -## Running Tests - -The environment includes a suite of tests to ensure its core logic is working correctly. These tests verify that the environment can be reset, that actions are processed, and that the reward functions are behaving as expected. - -### Prerequisites - -You must have `pytest` installed: -```bash -pip install pytest -``` - -### How to Run - -From the **root directory** of the `OpenEnv` project, run the following commands: - -```bash -# Activate your virtual environment if you have one -source venv/bin/activate - -# Set the PYTHONPATH -export PYTHONPATH=src - -# Run the tests -pytest tests/envs/test_dipg_environment.py -pytest tests/envs/test_dipg_client.py -pytest tests/envs/test_dipg_reward_functions.py -``` - -A successful run will show an output indicating that all tests passed. - -### Test Structure - -- `tests/envs/test_dipg_environment.py`: This is an end-to-end test that starts the server, connects a client, and tests the `reset()` and `step()` functions. -- `tests/envs/test_dipg_client.py`: These are unit tests for the client, checking for error handling with invalid URLs and server timeouts. -- `tests/envs/test_dipg_reward_functions.py`: These are unit tests for the reward functions, ensuring they calculate scores correctly for different scenarios. - -## Core Components - -* **`models.py`**: Defines the data structures for interaction: - * `DIPGObservation`: Contains the `context` and `question` served to the agent. - * `DIPGAction`: Contains the `llm_response` generated by the agent. -* **`server/dipg_environment.py`**: The core of the environment. It loads the dataset, serves challenges via `reset()`, and calculates rewards via `step()`. -* **`client.py`**: The "remote control" that allows a Python script to communicate with the server over HTTP, handling all the JSON serialization and parsing. -* **`tests/`**: Contains the unit and integration tests for the environment. \ No newline at end of file diff --git a/src/envs/dipg_safety_env/__init__.py b/src/envs/dipg_safety_env/__init__.py deleted file mode 100644 index e69de29bb..000000000 diff --git a/src/envs/dipg_safety_env/client.py b/src/envs/dipg_safety_env/client.py deleted file mode 100644 index f5352d709..000000000 --- a/src/envs/dipg_safety_env/client.py +++ /dev/null @@ -1,112 +0,0 @@ -# src/envs/dipg_safety_env/client.py -""" -Client implementation for the custom DIPGSafetyEnv. - -This file defines the `DIPGSafetyEnv` class, which acts as the "remote control" -for the environment server.

Perfect for testing the env APIs as well as demonstrating environment usage patterns. - -## Quick Start - -The simplest way to use the Echo environment is through the `EchoEnv` class: - -```python -from envs.echo_env import EchoAction, EchoEnv - -try: - # Create environment from Docker image - echo_env = EchoEnv.from_docker_image("echo-env:latest") - - # Reset - result = echo_env.reset() - print(f"Reset: {result.observation.echoed_message}") - - # Send multiple messages - messages = ["Hello, World!", "Testing echo", "Final message"] - - for msg in messages: - result = echo_env.step(EchoAction(message=msg)) - print(f"Sent: '{msg}'") - print(f" → Echoed: '{result.observation.echoed_message}'") - print(f" → Length: {result.observation.message_length}") - print(f" → Reward: {result.reward}") - -finally: - # Always clean up - echo_env.close() -``` - -That's it! The `EchoEnv.from_docker_image()` method handles: -- Starting the Docker container -- Waiting for the server to be ready -- Connecting to the environment -- Container cleanup when you call `close()` - -## Building the Docker Image - -Before using the environment, you need to build the Docker image: - -```bash -# From project root -docker build -t echo-env:latest -f src/envs/echo_env/server/Dockerfile . -``` - -## Environment Details - -### Action -**EchoAction**: Contains a single field -- `message` (str) - The message to echo back - -### Observation -**EchoObservation**: Contains the echo response and metadata -- `echoed_message` (str) - The message echoed back -- `message_length` (int) - Length of the message -- `reward` (float) - Reward based on message length (length × 0.1) -- `done` (bool) - Always False for echo environment -- `metadata` (dict) - Additional info like step count - -### Reward -The reward is calculated as: `message_length × 0.1` -- "Hi" → reward: 0.2 -- "Hello, World!" → reward: 1.3 -- Empty message → reward: 0.0 - -## Advanced Usage - -### Connecting to an Existing Server - -If you already have an Echo environment server running, you can connect directly: - -```python -from envs.echo_env import EchoEnv - -# Connect to existing server -echo_env = EchoEnv(base_url="") - -# Use as normal -result = echo_env.reset() -result = echo_env.step(EchoAction(message="Hello!")) -``` - -Note: When connecting to an existing server, `echo_env.close()` will NOT stop the server. - -## Development & Testing - -### Direct Environment Testing - -Test the environment logic directly without starting the HTTP server: - -```bash -# From the server directory -python3 src/envs/echo_env/server/test_echo_env.py -``` - -This verifies that: -- Environment resets correctly -- Step executes actions properly -- State tracking works -- Rewards are calculated correctly - -### Running the Full Example - -Run the complete example that demonstrates the full workflow: - -```bash -python3 examples/local_echo_env.py -``` - -This example shows: -- Creating an environment from a Docker image -- Resetting and stepping through the environment -- Automatic cleanup with `close()` -

-A wrapper around [FinRL](https://github.com/AI4Finance-Foundation/FinRL) stock trading environments that conforms to the OpenEnv specification. - -## Overview - -This environment enables reinforcement learning for stock trading tasks using FinRL's powerful StockTradingEnv, exposed through OpenEnv's simple HTTP API. It supports: - -- **Stock Trading**: Buy/sell actions across multiple stocks -- **Portfolio Management**: Track balance, holdings, and portfolio value -- **Technical Indicators**: MACD, RSI, CCI, DX, and more -- **Flexible Configuration**: Custom data sources and trading parameters - -## Quick Start - -### 1. Build the Docker Image - -First, build the base image (from OpenEnv root): - -```bash -cd OpenEnv -docker build -t envtorch-base:latest -f src/core/containers/images/Dockerfile . -``` - -Then build the FinRL environment image: - -```bash -docker build -t finrl-env:latest -f src/envs/finrl_env/server/Dockerfile . -``` - -### 2. Run the Server - -#### Option A: With Default Sample Data - -```bash -docker run -p 8000:8000 finrl-env:latest -``` - -This starts the server with synthetic sample data for testing. - -#### Option B: With Custom Configuration - -Create a configuration file `config.json`: - -```json -{ - "data_path": "/data/stock_data.csv", - "stock_dim": 3, - "hmax": 100, - "initial_amount": 100000, - "num_stock_shares": [0, 0, 0], - "buy_cost_pct": [0.001, 0.001, 0.001], - "sell_cost_pct": [0.001, 0.001, 0.001], - "reward_scaling": 0.0001, - "state_space": 25, - "action_space": 3, - "tech_indicator_list": ["macd", "rsi_30", "cci_30", "dx_30"] -} -``` - -Run with configuration: - -```bash -docker run -p 8000:8000 \ - -v $(pwd)/config.json:/config/config.json \ - -v $(pwd)/data:/data \ - -e FINRL_CONFIG_PATH=/config/config.json \ - finrl-env:latest -``` - -### 3.

sumo-rl-env:latest -``` - -## Observation - -The observation is a vector containing: -- **Phase one-hot**: Current active green phase (one-hot encoded) -- **Min green flag**: Binary indicator if minimum green time has passed -- **Lane densities**: Number of vehicles / lane capacity for each incoming lane -- **Lane queues**: Number of queued vehicles / lane capacity for each incoming lane - -Observation size varies by network topology (depends on number of phases and lanes). - -**Default (single-intersection)**: -- 4 green phases -- 8 incoming lanes -- Observation size: ~21 elements - -## Action Space - -The action space is discrete and represents selecting the next green phase to activate. - -- **Action type**: Discrete -- **Action range**: `[0, num_green_phases - 1]` -- **Default (single-intersection)**: 4 actions (one per green phase) - -When a phase change is requested, SUMO automatically inserts a yellow phase before switching. - -## Rewards - -Default reward function is **change in cumulative waiting time**: -``` -reward = -(total_waiting_time_now - total_waiting_time_previous) -``` - -Positive rewards indicate waiting time decreased (good). - -### Available Reward Functions - -Set via `SUMO_REWARD_FN` environment variable: - -- **`diff-waiting-time`** (default): Change in cumulative waiting time -- **`average-speed`**: Average speed of all vehicles -- **`queue`**: Negative total queue length -- **`pressure`**: Pressure metric (incoming - outgoing vehicles) - -## Configuration - -### Environment Variables - -| Variable | Default | Description | -|----------|---------|-------------| -| `SUMO_NET_FILE` | `/app/nets/single-intersection.net.xml` | Network topology file | -| `SUMO_ROUTE_FILE` | `/app/nets/single-intersection.rou.xml` | Vehicle routes file | -| `SUMO_NUM_SECONDS` | `20000` | Simulation duration (seconds) | -| `SUMO_DELTA_TIME` | `5` | Seconds between agent actions | -| `SUMO_YELLOW_TIME` | `2` | Yellow phase duration (seconds) | -| `SUMO_MIN_GREEN` | `5` | Minimum green time (seconds) | -| `SUMO_MAX_GREEN` | `50` | Maximum green time (seconds) | -| `SUMO_REWARD_FN` | `diff-waiting-time` | Reward function name | -| `SUMO_SEED` | `42` | Random seed (use for reproducibility) | -

action_mask: List[int] # Valid action indices - sim_time: float # Current simulation time - done: bool # Episode finished - reward: Optional[float] # Reward from last action - metadata: Dict # System metrics -``` - -### SumoState - -```python -@dataclass -class SumoState(State): - episode_id: str # Unique episode ID - step_count: int # Steps taken - net_file: str # Network file path - route_file: str # Route file path - sim_time: float # Current simulation time - total_vehicles: int # Total vehicles in simulation - total_waiting_time: float # Cumulative waiting time - mean_waiting_time: float # Mean waiting time - mean_speed: float # Mean vehicle speed -

-env.close() -``` - -## Performance Notes - -### Simulation Speed - -- **Reset time**: 1-5 seconds (starts new SUMO simulation) -- **Step time**: ~50-200ms per step (depends on network size) -- **Episode duration**: Minutes (20,000 sim seconds with delta_time=5 → ~4,000 steps) - -### Optimization - -For faster simulation: -1. Reduce `SUMO_NUM_SECONDS` for shorter episodes -2. Increase `SUMO_DELTA_TIME` for fewer decisions -3.

Run it from the repo root: - -```bash -python examples/textarena_simple.py -``` - -The script uses `TextArenaEnv.from_docker_image` to automatically build/run the container if needed.

/dev/null +++ b/envs/README.md @@ -0,0 +1,382 @@ +# Building Your Own Environment + +This guide shows you how to create a custom environment using the EnvTorch framework. + +## Overview + +Creating an environment involves five main steps: +1. Define your models (Action, Observation, State) +2. Implement the environment APIs: step, reset, state +3. Create the FastAPI server +4. Build a Docker image and push it to a public docker repo for community to access it +5. Subclass HTTPEnvclient and implement the parsing methods for result and state. + +## Step-by-Step Guide + +### 1. Define Models + +Create your action, observation, and state models using Python dataclasses: + +```python +# models.py +from dataclasses import dataclass +from openenv.core.env_server import Action, Observation, State + +@dataclass +class MyAction(Action): + """Your custom action.""" + command: str + parameters: dict + +@dataclass +class MyObservation(Observation): + """Your custom observation.""" + result: str + success: bool + +@dataclass +class MyState(State): + """Custom state fields.""" + custom_field: int = 0 +``` + +### 2. Implement Environment + +Implement the three core methods: `reset()`, `step()`, and `state`: + +```python +# server/my_environment.py +import uuid +from openenv.core.env_server import Environment +from ..models import MyAction, MyObservation, MyState + +class MyEnvironment(Environment): + def __init__(self): + super().__init__() + self._state = MyState() + + def reset(self) -> MyObservation: + self._state = MyState(episode_id=str(uuid.uuid4())) + return MyObservation(result="Ready", success=True) + + def step(self, action: MyAction) -> MyObservation: + # Implement your logic here + self._state.step_count += 1 + result = self._execute_command(action.command) + return MyObservation(result=result, success=True) + + @property + def state(self) -> MyState: + return self._state +``` + +### 3. Create FastAPI Server + +Use the `create_fastapi_app` helper to create your HTTP server: + +```python +# server/app.py +from openenv.core.env_server import create_fastapi_app +from ..models import MyAction, MyObservation +from .my_environment import MyEnvironment + +env = MyEnvironment() +app = create_fastapi_app(env, MyAction, MyObservation) +``` + +### 4. Define Dependencies + +**For Python-only dependencies (most common case):** + +Create `envs/my_env/server/requirements.txt`: +```txt +your-package>=1.0.0 +another-package +``` + +**For complex setup (optional, only if needed):** + +If you need additional setup beyond pip install, create `envs/my_env/server/install_deps.sh`: +```bash +#!/bin/bash +set -e + +# Install Python dependencies +pip install --no-cache-dir -r /tmp/requirements.txt + +# Additional setup commands (only if needed) +mkdir -p /some/directory +# ... other setup steps +``` + +### 5. Create Dockerfile + +Build your Docker image from the openenv-base. Place this at `envs/my_env/server/Dockerfile`: + +**Simple case (just requirements.txt):** +```dockerfile +# Accept base image as build argument for CI/CD flexibility +ARG BASE_IMAGE=openenv-base:latest +FROM ${BASE_IMAGE} + +# Install dependencies +COPY envs/my_env/server/requirements.txt /tmp/requirements.txt +RUN pip install --no-cache-dir -r /tmp/requirements.txt && rm /tmp/requirements.txt + +# Copy environment code +COPY src/core/ /app/src/core/ +COPY envs/my_env/ /app/envs/my_env/ + +# Health check +HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \ + CMD curl -f http://localhost:8000/health || exit 1 + +# Run server +CMD ["uvicorn", "envs.my_env.server.app:app", "--host", "0.0.0.0", "--port", "8000"] +``` + +**Complex case (requirements.txt + install_deps.sh):** +```dockerfile +ARG BASE_IMAGE=openenv-base:latest +FROM ${BASE_IMAGE} + +# Install dependencies and run setup +COPY envs/my_env/server/requirements.txt /tmp/requirements.txt +COPY envs/my_env/server/install_deps.sh /tmp/install_deps.sh +RUN chmod +x /tmp/install_deps.sh && \ + /tmp/install_deps.sh && \ + rm /tmp/install_deps.sh /tmp/requirements.txt + +# Copy environment code +COPY src/core/ /app/src/core/ +COPY envs/my_env/ /app/envs/my_env/ + +# Health check +HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \ + CMD curl -f http://localhost:8000/health || exit 1 + +# Run server +CMD ["uvicorn", "envs.my_env.server.app:app", "--host", "0.0.0.0", "--port", "8000"] +``` + +### 5. Update GitHub Actions Workflow + +**Important**: To enable automatic Docker image builds on GitHub, add your environment to the workflow matrix. + +Edit `.github/workflows/docker-build.yml` and add your environment to the matrix: + +```yaml +strategy: + matrix: + image: + - name: echo-env + dockerfile: envs/echo_env/server/Dockerfile + - name: chat-env + dockerfile: envs/chat_env/server/Dockerfile + - name: coding-env + dockerfile: envs/coding_env/server/Dockerfile + - name: my-env # Add your environment here + dockerfile: envs/my_env/server/Dockerfile +``` + +Once added, every push to `main` will automatically: +- Build your Docker image +- Push it to GitHub Container Registry as `ghcr.io/YOUR_USERNAME/openenv-my-env:latest` + +### 6. Implement Client + +Create a client that extends `HTTPEnvClient`: + +```python +# client.py +from openenv.core.http_env_client import HTTPEnvClient +from openenv.core.types import StepResult +from .models import MyAction, MyObservation, MyState + +class MyEnv(HTTPEnvClient[MyAction, MyObservation]): + def _step_payload(self, action: MyAction) -> dict: + return {"command": action.command, "parameters": action.parameters} + + def _parse_result(self, payload: dict) -> StepResult[MyObservation]: + obs = MyObservation(**payload["observation"]) + return StepResult( + observation=obs, + reward=payload.get("reward"), + done=payload.get("done", False), + ) + + def _parse_state(self, payload: dict) -> MyState: + return MyState(**payload) +``` + +## Building and Using Your Environment + +### Build Docker Images + +```bash +# First, build the base image (if not already built) +docker build -t openenv-base:latest -f src/core/containers/images/Dockerfile . + +# Then build your environment image +docker build -t my-env:latest -f envs/my_env/server/Dockerfile . +``` + +### Use Your Environment + +```python +from envs.my_env import MyAction, MyEnv + +# Create environment from Docker image +client = MyEnv.from_docker_image("my-env:latest") + +# Reset +result = client.reset() +print(result.observation.result) # "Ready" + +# Execute actions +result = client.step(MyAction(command="test", parameters={})) +print(result.observation.result) +print(result.observation.success) + +# Get state +state = client.state() +print(state.episode_id) +print(state.step_count) + +# Cleanup +client.close() +``` + +## Project Structure + +Organize your environment following this structure: + +``` +envs/my_env/ +├── __init__.py # Export MyAction, MyObservation, MyState, MyEnv +├── models.py # Action, Observation, State definitions +├── client.py # MyEnv client implementation +├── README.md # Environment documentation +└── server/ + ├── __init__.py + ├── my_environment.py # Environment logic + ├── app.py # FastAPI application + └── Dockerfile # Docker image definition +``` + +## Example Environments + +Study these examples to see the patterns in action: + +### Echo Environment +Location: `envs/echo_env/` + +A minimal environment that echoes messages back.

Demonstrates: +- Complex environment logic +- Error handling +- External tool integration (smolagents) + +See: [`coding_env/README.md`](coding_env/README.md) + +## Best Practices + +### 1. Type Safety +Always use typed dataclasses for actions, observations, and state: +```python +@dataclass +class MyAction(Action): + command: str # Use explicit types + count: int = 0 # Provide defaults when appropriate +``` + +### 2. Error Handling +Handle errors gracefully in your environment: +```python +def step(self, action: MyAction) -> MyObservation: + try: + result = self._process(action) + return MyObservation(result=result, success=True) + except Exception as e: + return MyObservation(result="", success=False, error=str(e)) +``` + +### 3. State Management +Track all relevant episode state: +```python +@dataclass +class MyState(State): + # Add custom fields + accumulated_reward: float = 0.0 + last_action: str = "" +``` + +### 4. Documentation +Provide comprehensive README for your environment: +- Overview and purpose +- Quick start example +- Action/Observation specifications +- Build instructions +- Usage examples + +### 5.

Perfect for learning basic web navigation skills. **No external setup needed** - tasks run in isolated browser sessions. + +- **WebArena (Evaluation)**: 812 tasks on real websites (e-commerce, forums, GitLab, Wikipedia). Tasks like "find the cheapest laptop and add to cart" or "create a merge request for bug #123". Multistep, requires reasoning, sparse rewards. Tests if your agent can handle actual websites. **Requires running 7 backend services** (shopping site, GitLab instance, etc.). + +- **VisualWebArena**: Similar to WebArena but requires visual understanding - agents need to interpret images, identify UI elements visually, handle multimodal content. + +- **WorkArena**: Enterprise software tasks (CRM, project management, business workflows). Tests automation on corporate-style applications. + +**The training → evaluation pipeline:** +1. Train on MiniWoB (simple, controlled, fast iterations) +2.

high-stakes AI safety. It was developed to address a critical use case: ensuring the reliability and safety of a Large Language Model (LLM) agent operating in the medical domain of **Diffuse Intrinsic Pontine Glioma (DIPG)**, a universally fatal pediatric brain tumor. + +In this context, an AI's failure is not an option. The environment's primary purpose is to train and rigorously evaluate an agent's ability to: +1. Base its answers *only* on the verified clinical context provided. +2. Correctly identify and report conflicting information from different sources. +3. Safely abstain from answering when the context is insufficient. +4. Strictly avoid hallucinating facts or providing unsafe, unsupported information. + +## Features + +The environment server contains a suite of safety-critical reward functions that score an agent's response based on the following behaviors: + +* **Conflict Identification:** Rewards the agent for correctly stating that provided sources are contradictory. +* **Knowledge Abstention:** Rewards the agent for recognizing when a question cannot be answered from the given text and explicitly saying so. +* **Format Adherence:** Positively or negatively scores the response based on its adherence to a required structured output format. +* **Hallucination Penalty:** Heavily penalizes the agent for generating any information that is not supported by the provided context. + +## Getting Started: How to Use the Environment + +The `DIPGSafetyEnv` follows a standard client-server model. + +### 1. Running the Server + +The server requires the custom synthetic dataset (`harmonic_reasoner_dataset_structured.jsonl`). You can download it from [here](https://huggingface.co/datasets/dvitel/Harmonic-Reasoner/resolve/main/harmonic_reasoner_dataset_structured.jsonl). + +The recommended way to run the server is with `gunicorn` for better performance and stability. + +```bash +# Install gunicorn +pip install gunicorn + +# Set the dataset path environment variable +export DIPG_DATASET_PATH=/path/to/your/harmonic_reasoner_dataset_structured.jsonl + +# Run the server +PYTHONPATH=./src gunicorn -w 4 -k uvicorn.workers.UvicornWorker -b 0.0.0.0:8009 envs.dipg_safety_env.server.app:app +``` + +### 2. Interacting from the Client + +Once the server is running, an agent can interact with it using the `DIPGSafetyEnv` client. + +```python +from envs.dipg_safety_env.client import DIPGSafetyEnv +from envs.dipg_safety_env.models import DIPGAction + +# Connect to the running server +env = DIPGSafetyEnv(base_url="http://localhost:8009", timeout=60) + +# Start a new episode and get the first challenge +# The 'obs' object will contain a medical context and a question. +obs = env.reset() +print(f"Question: {obs.observation.question}") + +# The agent processes the observation and generates a response +agent_response_text = "Based on the provided context, the information is conflicting." + +# Send the response (as an Action) to the environment to be scored +action = DIPGAction(llm_response=agent_response_text) +result = env.step(action) + +# The result contains the reward and a flag indicating the episode is done +print(f"Reward: {result.reward}") +print(f"Done: {result.done}") +``` + +## Running Tests + +The environment includes a suite of tests to ensure its core logic is working correctly. These tests verify that the environment can be reset, that actions are processed, and that the reward functions are behaving as expected. + +### Prerequisites + +You must have `pytest` installed: +```bash +pip install pytest +``` + +### How to Run + +From the **root directory** of the `OpenEnv` project, run the following commands: + +```bash +# Activate your virtual environment if you have one +source venv/bin/activate + +# Set the PYTHONPATH +export PYTHONPATH=src + +# Run the tests +pytest tests/envs/test_dipg_environment.py +pytest tests/envs/test_dipg_client.py +pytest tests/envs/test_dipg_reward_functions.py +``` + +A successful run will show an output indicating that all tests passed. + +### Test Structure + +- `tests/envs/test_dipg_environment.py`: This is an end-to-end test that starts the server, connects a client, and tests the `reset()` and `step()` functions. +- `tests/envs/test_dipg_client.py`: These are unit tests for the client, checking for error handling with invalid URLs and server timeouts. +- `tests/envs/test_dipg_reward_functions.py`: These are unit tests for the reward functions, ensuring they calculate scores correctly for different scenarios. + +## Core Components + +* **`models.py`**: Defines the data structures for interaction: + * `DIPGObservation`: Contains the `context` and `question` served to the agent. + * `DIPGAction`: Contains the `llm_response` generated by the agent. +* **`server/dipg_environment.py`**: The core of the environment. It loads the dataset, serves challenges via `reset()`, and calculates rewards via `step()`. +* **`client.py`**: The "remote control" that allows a Python script to communicate with the server over HTTP, handling all the JSON serialization and parsing. +* **`tests/`**: Contains the unit and integration tests for the environment. \ No newline at end of file diff --git a/envs/dipg_safety_env/__init__.py b/envs/dipg_safety_env/__init__.py new file mode 100644 index 000000000..e69de29bb diff --git a/envs/dipg_safety_env/client.py b/envs/dipg_safety_env/client.py new file mode 100644 index 000000000..9e556481f --- /dev/null +++ b/envs/dipg_safety_env/client.py @@ -0,0 +1,112 @@ +# envs/dipg_safety_env/client.py +""" +Client implementation for the custom DIPGSafetyEnv. + +This file defines the `DIPGSafetyEnv` class, which acts as the "remote control" +for the environment server.
