I tried compiling PyTorch for the CPU with the config shown in the attached image, yet I’m still getting this error:

PS D:\Python\StockEmulateAI> python3.13t -c "import torch"                             
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import torch
  File "C:\Users\Bogdan\AppData\Local\Programs\Python\Python313\Lib\site-packages\torch\__init__.py", line 1003, in <module>
    raise ImportError(
    ...<14 lines>...
    ) from None
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 setup.py install && python -c "import torch"

    This error can generally be solved using the `develop` workflow
        $ python setup.py develop && python -c "import torch"  # This should succeed   
    or by running Python from a different directory.

Hey!

As the error suggests, did you try changing folder? The error often happens when Python confuses a local folder for the actual install (due to how python prioritizes local files).

There’s no torch.py script in my directory, but I tried what you suggested either way! …It didn’t work. I should mention that the error only occurs when using python3.13t (no GIL).

Just tried from scratch and it works fine on linux. This might be a windows issue then.
Could you open an issue on github please?
