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.
