Problem with importing torch in a conda environment using python3.8

[loic.sacre]

I have created a conda environement using the environment.yml file located in the folder ~/.local/share/ov/pkg/isaac_sim-2022.1.0. The only thing I have modified is the line with python=3.7 which I changed to python=3.8.

However, when trying to import torch, the following error occurs:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/ragi/.local/share/ov/pkg/isaac_sim-2022.1.0/exts/omni.isaac.ml_archive/pip_prebundle/torch/__init__.py", line 216, in <module>
    raise ImportError(textwrap.dedent('''
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.

I don’t have any problem with python 3.7. Has anyone an idea on how to solve that ?

Omniverse and Isaac sim currently only support python 3.7. All of the internal code/bindings are compiled against that specific python version
