[QST] Does it support Windows?

[Ian990466]

I tried #86 (comment) on Windows 10, but it is not working with version v25.08.00.
Does it support Windows now via pip install?
When I run the code on WSL2, it is slower than running it on native Ubuntu, but due to certain restrictions, I need to use this library on Windows.

Hi @Ian990466,

Was your issue also related to symbolic links as discussed here?

We unfortunately have not had time yet to add a windows wheel for pip

No, I think it seems like it doesn't find the CUDA toolkit when building the wheel.
