[MeyerBender]

Describe the bug
Running cellpose with PyTorch version 2.5.1.post303 leads to the following error:

    major_version, minor_version, _ = torch.__version__.split(".")
ValueError: too many values to unpack (expected 3)

Should be fairly easy to fix by simple replacing the corresponding line with something like this:

torch_version = torch.__version__.split(".")
major_version, minor_version = torch_version[0], torch_version[1]
