[SOLVED] compatiblity of pytorch and cuda in venv

In the official repo, e.g. python-pytorch-cuda is always compatible with cuda(v13.1).
But in venv pytorch is installed by pip,
pytorch installed  by

pip3 install torch torchvision --index-url https://download.pytorch.org/whl/cu130

Is it compatible with cuda 13.1 in the official repo?

Is it better to use conda to make torch and cuda always compatible?
Or what is the best practice to install pytorch with cuda support in venv?

`pip3 install torch torchvision --index-url https://download.pytorch.org/whl/cu130` will install cuda 13.0 in venv

Only if you use torch & cuda exclusively with conda.
Keep in mind conda is known to break archlinux functionality unless conda is blocked from interfering with system installed python .

uv in enough for me now,
and pytorch also doesn't support conda any more,
so I'll not use conda now.
