Issues with CPU-only torch and deprecated setup.py bdist_wheel

[akashbeh]

I had two issues when using CPU-only torch. Fixed both by using GPU torch.

Running Linux PureOS. Installed CPU-only torch with pip3 install torch torchvision --index-url https://download.pytorch.org/whl/cpu as specified on https://pytorch.org/get-started/locally/ . Then

1. Installation failed due to deprecated bdist_wheel (See 1-install.log. Packages are cached because I had just run with --dry-run.)

There were several errors preventing compiling. I also got warnings such as DEPRECATION: Building 'unidic' using the legacy setup.py bdist_wheel mechanism which led me to pypa/pip#6334. Rerunning with --use-pep517 fixed it. (See 2-pep517.log)

The github link says that project authors should add a pyproject.toml file.

2. Running failed (see 3-run.log)

OSError: libtorch_cuda.so: cannot open shared object file: No such file or directory

I fixed this by reinstalling torch and torchvision. No reinstall of torchaudio or melotts was necessary. (See 4-reinstall.log)
