How can I install with pytorch bugfix without compile

1

For example, 2.0.1 update with bugfix on mps, but it is hard to use pip / conda to install the fixed version (since no update on registry)

Release PyTorch 2.0.1 Release, bug fix release · pytorch/pytorch · GitHub

If the fix touches purely Python files you could directly manipulate them in the installed folder of your binaries. To do so you can search for the corresponding files in torch.__path__.
However, if source files were changes which need to be compiled, such as .cpp files, you would need to rebuild PyTorch from source.
