Unexpected switch to GraalPy causing PyTorch C-extension import error

[VaralikaAg]

I'm encountering a strange issue when running trainModifyCondition.py.

When I start Python, my environment is expected to use Python 3.10.x (CPython).
However, during execution, it unexpectedly switches to GraalPy 3.10.8 (GraalVM CE JVM 23.0.0), which causes PyTorch to fail loading C extensions.

Here is the exact error:

ImportError: Failed to load PyTorch C extensions:
    It appears that PyTorch has loaded the `torch/_C` folder
    of the PyTorch repository rather than the C extensions which
    are expected in the `torch._C` namespace.

After that, checking the Python version shows:

python --version
GraalPy 3.10.8 (GraalVM CE JVM 23.0.0)

Hi Varalika ,

For better understanding of the issue can you please let me know the exact line from code.

I am encountering the following error and I'm unable to pinpoint the root cause in the code:

Traceback (most recent call last):
  File "/teamspace/studios/this_studio/WordDiffusion/trainModifyCondition.py", line 26, in <module>
    import torch
  File "/system/conda/miniconda3/envs/cloudspace/lib/jvm/languages/python/lib/python3.10/site-packages/torch/__init__.py", line 1013, in <module>

ImportError: Failed to load PyTorch C extensions:
    It appears that PyTorch has loaded the `torch/_C` folder
    of the PyTorch repository rather than the C extensions which
    are expected in the `torch._C` namespace. This can occur when
    using the `install` workflow. e.g.
        $ python -m pip install --no-build-isolation -v . && python -c "import torch"

    This error can generally be solved using the `develop` workflow
        $ python -m pip install --no-build-isolation -v -e . && python -c "import torch"  # This should succeed
    or by running Python from a different directory.

I have added requirment.txt try using that.
