Problem setting up in Windows venv

[Kncuk]

Hi, I am trying to do the build using the whl from release, in a venv.
I am using the cp313+cu13.2+torch2.11 whl, the system is on cu13.2.
I had the following when attempting to run python convert.py -h to test the installation

...\venv\Lib\site-packages\pydantic\_migration.py", line 314, in wrapper
raise AttributeError(f'module {module!r} has no attribute {name!r}')
AttributeError: module 'pydantic.typing' has no attribute 'Type'

I have encountered issues with:
flash_attn (seemingly fixed using existing wheel, as recommended by turboderp in discord )

xformers version mismatch (ended up using Facebook wheel)

triton (ended up install triton_windows before building)

If there's documentation on proper installation please let me know.

I've updated the readme a bit. I can't really do anything about the way xformers versions are coupled to Torch versions. Or at least I'm not sure how to address it.

The pydantic.typing issue comes from Formatron, I believe, or rather breaking changes in Pydantic that affect Formatron. One quick fix is to pin pydantic at version 2.11.0, or it might be fixed by upgrading formatron to 0.5.0. I'm investigating to see if I can find a real solution, but it's incredibly hard to keep up with breaking changes in dependencies.

Thanks. I have tested formatron 0.5.0 for the time being, and the same error is showing up.
Pinning Pydantic to 2.11.0 solved the issue, so that is likely the issue.
I will close this issue now. Thanks

I'll keep this open for the time being just so I don't lose track of it. Really needs a proper fix one way or another.
