I have python 3.9.20 environment with PyTorch and CUDA installed.
cuda version :12.4

(monailabel) C:\Users\Administrator>python
Python 3.9.20 (main, Oct 3 2024, 07:38:01) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

import torch
print(torch.cuda.is_available())
True

But, I get the following error when running monailabel：

(monailabel) C:\Users\Administrator>monailabel

The issue is not that you use Windows11 but that you use Python-3.9.

I have run into the same issue. The problem was easy to fix (just use get method and tweak the sorting), but then when I noticed that there were further issues (SAM is not supported on Python 3.9) then I just gave up.

The error happens when you import MONAILabel, so it seems MONAILabel is not tested at all with Python-3.9 (or the failure is ignored), so I'm not sure if MONAILabel is supported on Python-3.9.

Try: pip install importlib_metadata==8.4.0
if works, then please share the existing package version details for the above.

is all good?

If it helps at all, for me, with Python-3.9 MONAILabel failed on this line:

MONAILabel/monailabel/config.py

Line 20 in 1fe0e8f

return name in sorted(x.name for x in distributions())

I've tried installing various importlib_metadata versions but in the end I've fixed the issue by changing the code to this:

return name in (x.metadata.get('Name') for x in distributions())

(It seems that I removed the sorting, I don't know why, maybe that was causing some issue, too, and you probably don't really need the sorting anyway)

Since then I decided to switch to Python-3.10, so I did not investigate Python-3.9 any further.
