Hi,  
I’m having trouble applying the program ‘Total Segmentator’. I’ve tried every possible method below Mr Anish\_Raj’s question posted on December 22, 2022 but still encountered a failure about PyTorch as mentioned in the topic.  
Detailed error:  
Traceback (most recent call last):  
File “E:\Slicer 5.2.2\bin\Python\slicer\util.py”, line 2967, in tryWithErrorDisplay  
yield  
File “E:/Slicer 5.2.2/NA-MIC/Extensions-31382/TotalSegmentator/lib/Slicer-5.2/qt-scripted-modules/TotalSegmentator.py”, line 255, in onApplyButton  
self.logic.setupPythonRequirements()  
File “E:/Slicer 5.2.2/NA-MIC/Extensions-31382/TotalSegmentator/lib/Slicer-5.2/qt-scripted-modules/TotalSegmentator.py”, line 618, in setupPythonRequirements  
torch = torchLogic.installTorch(askConfirmation=True)  
File “E:/Slicer 5.2.2/NA-MIC/Extensions-31382/PyTorch/lib/Slicer-5.2/qt-scripted-modules/PyTorchUtils.py”, line 195, in installTorch  
import torch  
ModuleNotFoundError: No module named ‘torch’  
Please tell me which steps need to be corrected,  
Thanks.

Thanks a lot for your instructions, it turned out to be a problem with the modules of Python that I installed before, and the performance of my hardware was not good enough for some examples about image processing. I tried your steps again strictly in the lab for postgraduates and got the results successfully.
