Hi,
I am unable to use the Dental Segmentator module. I am using slicer 5.8, Pytorch version is 2.6.0 + cu118. I have tried manually downloading the weights and adding it to the Recources/ML folder. However, I am still getting the following error in the log:
2025/01/30 09:50:19.665 :: nnUNet is already installed (2.5.1) and compatible with requested version (nnunetv2).

2025/01/30 09:50:33.781 :: (1) In PyTorch 2.6, we changed the default value of the weights_only argument in torch.load from False to True. Re-running torch.load with weights_only set to False will likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source.
2025/01/30 09:50:33.781 :: (2) Alternatively, to load with weights_only=True please check the recommended steps in the following error message.

Could someone please look into the issue and recommend some possible workarounds?
