The problem is that the file libtorch_python.so.* is specific to one 
python version, and cannot be shared between py3.11 and py3.12. One of 
them will break if we do setup.py for both versions.


Thanks a lot for giving this a shot. This means that all reverse 
dependencies of pytorch will have to support default Python only.


Best wishes,

I tried this and it turns to be a little bit complicated to support. The 
code change can be found in the git history, which was reverted by me.

Upstream is not interested to fix this since libtorch_python.so is 
already big enough (25MB).


I don't want to spend my time for simultaneously supporting multiple 
python versions anymore. And I don't see any problem by only supporting 
the default python version. A couple of lines of code change can limit 
reverse dependencies to a single python version.


Patch is appreciated if anybody can make it work. Make sure that both 
py3.11 and py3.12 `import torch` works correctly.
