https://github.com/pytorch/vision/pulls?q=is%3Apr+python+3.10+is%3Aclosed 
seems to indicate that an upgrade to upstream's 0.12 is needed to properly 
support python 3.10

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.
