Troubleshooting
Missing libcufft.so
If you're getting error like OSError: libcufft.so.11: cannot open shared object file: No such file or directory
it may be because your system doesn't have an NVidia GPU. A possible workaround is to use the CPU version of PyTorch:
$ pip3 install torch --extra-index-url https://download.pytorch.org/whl/cpu
