Error in PyTorch installation

[Ben]

I am installing Totalsegmentation in Windows 10, after the installation, I continued to install the PyTorch, and got the error:

I already uninstall, restart, reinstall, and restart, there is no difference.

My setup is:
I7-10700CPU@2.90GHz
64GB RAM
Windows 10 Pro
NIVIDIA GeForce RTX 3060 Ti, Driver version 560.94
NIVIDIA GeForce Experience Version 3.28.0.417
3D Slicer Version 5.6.2

The details of the error are as follows:

Please advise.
Thanks.

Please check the application log, Python console, or the textbox under the Apply button in the TotalSegmentator module. There should be some more specific information about why light-the-torch installation fails.

Thanks for the reply.

@Ben

error: Application does NOT exists [C:/Users/User/AppData/Local/slicer.org/Slicer 5.6.2/bin/./python-real.exe]

This is an important message.

Does this file exist on your computer?

C:\Users\User\AppData\Local\slicer.org\Slicer 5.6.2\bin\python-real.exe

(I guess you need to replace User by your actual username)

Does your username contain special (non-ASCII) characters?

[jamesobutler (James Butler)]

Or has Windows Defender or other antivirus incorrectly quarantined python-real.exe making it no longer exist at that location?

[Ben]

Yes, thanks. I have Norton, it probably blocked some actions in the installation.
I can find the file in the folder.

I reinstalled Slicer 5.6.2, and PyTorch, giving it an exception for Norton’s blocking action
Can install PyTorch version 1.81
Uninstalled 1.81 and reinstall with “>1.12” in the version requirement
Again give an exception for Norton’s blocking action
Then I received the following error:
