Import Error + CUDA 12.8 use.

[kalmary]

Hi!

First let me thank you for your hard work. I was looking for a tool like this for quite a while. When testing it I've faced some problems:

• installation's documentation doesn't specify the torch version, but when installing pointtree I get an error message about highest version of torch being <2.5. Unfortunately it doesn't work with any of rtx 5000 series gpus. Would you consider adding support for newer cards and more up to date versions of cuda?
• I try to overcome the first issue by installing the package directly from the repository, without its dependencies:

python3 -m venv .venv
cd .venv
git clone /repo_url    # change to actual url
source .venv/bin/activate
pip install torch==2.8.0 torchvision==0.23.0 torchaudio==2.8.0 --index-url https://download.pytorch.org/whl/cu128
cd pointtree
pip install . --no-deps
cd ..
pip install (libraries from .toml file)

Then I install all the packages from pointtree/pyproject.toml. It does let me import pointtree, but:

from pointtree.instance_segmentation import TreeXAlgorithm

gives me following error:

File "adress/.../treesegm_test.py", line 5, in <module>
    from pointtree.instance_segmentation import TreeXAlgorithm
  File "adress/.../.venv/lib/python3.12/site-packages/pointtree/instance_segmentation/__init__.py", line 5, in <module>
    from ._tree_x_algorithm import *
  File "adress/.../.venv/lib/python3.12/site-packages/pointtree/instance_segmentation/_tree_x_algorithm.py", line 10, in <module>
    from circle_detection import MEstimator, Ransac
ImportError: cannot import name 'MEstimator' from 'circle_detection' (adress/.../.venv/lib/python3.12/site-packages/circle_detection/__init__.py)

circle_detection==0.2.0 (required in .toml file as circle_detection>=0.1.0,<2.0.0 - the latest visible for me is 0.2.0) package does not have MEstimator nor Ransac methods. Its only method is detect_circles().

It is possible that I have installed an incorrect library. Please let me know if there's something I've missed.

Thank you and best regards!

Hi @kalmary,

we ran into the same problem and solved it via

pip install --force-reinstall git+https://github.com/josafatburmeister/circle_detection.git

Thanks for your feedback! The issue was caused by the latest pointtree main branch depending on corresponding main branch versions of the pointtorch and circle-detection packages.

I’ve now released a new version of pointtree that resolves this dependency mismatch. It should also be compatible with newer PyTorch versions.

You can install it using:

python -m pip install torch==2.10.0
python -m pip install torch-scatter torch-cluster -f https://data.pyg.org/whl/torch-2.10.0+cpu.html
python -m pip install pointtree
