PyTorch module not found

[gleesoi]

Hi I tried to install and run but it's giving me errors below. Am using windows 10 and cpu and I pip installed it with and without PyTorch. Wondering if this is known issue and any solution? ChatGPT mentions that PyTorch on Windows often requires the Microsoft Visual C++ Redistributable package?? I will try again with different torch version maybe but it appears once I install total segmentation torch 2.4 comes in.

The error message you're encountering, OSError: [WinError 126] The specified module could not be found. Error loading "C:\Users\glees\Desktop\TotalSegmentator\totalseg\lib\site-packages\torch\lib\fbgemm.dll" or one of its dependencies., indicates that a required DLL file or one of its dependencies for PyTorch could not be loaded.

This can often be due to missing dependencies or incompatible versions

Unfortunately I am not familiar with windows details. My test installation on windows is working.

ok got this working. i think its a torch 2.4 issue and some forums recently talking about same thing! this torch version comes in naturally when pip installing TotalSegmentator for me. so below worked for me:

python -m venv venv venv\Scripts\activate python -m pip install --upgrade pip pip install TotalSegmentator this brings in torch 2.4 anyways pip uninstall torch and say yes to its other things pip install torch==2.1.0 i tried this version first..... i get errors about nnunet needs torch >=2.1.2 and I have 2.1.0 so….. pip uninstall torch 2.1.0 pip install torch==2.1.2

run my script(dicom ct) using fastest option 6mm resolution – took ~37minutes for 6 rois subset !!

seems far too long to be used practically . when i run within 3dslicer ,total task fast completes within 3mins....?

Great that it works now! Maybe 3d Slicer is using your GPU (if you have one) or it is using the --fast option or the --roi_subset option ?

[gleesoi]

I don't have a gpu and slicer seems much quicker even when doing lots more rois.used fast options for both. not sure why big difference

Hi, I ran into the same issue described above with the torch version, 2.4 is not compatible. I uninstalled and resintalled torch version 2.1.2 which worked. It would be useful if you modified the torch requirement so it gets installed properly

Thanks for the report. On Linux and Mac this error does not occur therefore I do not really want to not allow pytorch 2.4 for those users. But it will add a note somewhere such that users are aware.
