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.
$ pthon setup.py install && python -c “import torch”
This error can generally be solved using the ‘develop’ work flow
$ python setup.py develop &&python -c “import torch” #This should succeed or by running Python from a different directory.
I find this error from the init.file:
