torch, torchao, and torchvision are not a part of pyproject.toml. According to docs, it's done because "it is not currently possible to properly support both nightly and stable installs of PyTorch + torchao in pyproject.toml."

Small issue is that if torchao is installed and torch is not, the error still says torchao is not installed. May waste some time for developers who encounter with this issue.

Also, there's no check for the third package, torchvision.
