the version numbers are different, even though the package names are the same. A stable version will have a version number such as `1.13.0`, where as a nightly version will have the date in the version number, such as `2.0.0.dev20221230`. You can check this either with `pip list | grep torch` or via `python -c "import torch; print(torch.__version__)"` If you installed `torch` via the instructions to install the nightly version specifically, then you get the nightly version. By default, you get the stable version of `torch`.
