bitsandbytes forces non-dev version of PyTorch

[t-vi]

System Info

When I have a dev version of PyTorch installed, the ~=2.0 dependency appears to cause PyTorch to be downgraded, which might not be intended. Quite likely >=2.0<3 would work better.

From an installation log:

Requirement already satisfied: torch~=2.0 in /opt/hostedtoolcache/Python/3.10.16/x64/lib/python3.10/site-packages (from bitsandbytes==0.45.1->-r requirements/test.txt (line 20)) (2.7.0.dev20250124+cpu)
Collecting torch~=2.0 (from bitsandbytes==0.45.1->-r requirements/test.txt (line 20))
  Downloading torch-2.5.1-cp310-cp310-manylinux1_x86_64.whl.metadata (28 kB)

I should say that it's not necessarily unreasonable to expect ~= to keep 2.7.0.dev... as a dependency but apparently, it does not.

Reproduction

To reproduce install nightly, e.g.

pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu124

and then bitsandbytes.

Expected behavior

keep the installed version of PyTorch
