I have installed pytorch using conda as well as pip command on ubuntu 19.10 with non-CUDA GPU. However, on attempting verification as metioned on the Get-Started page, Iget error messages which can be found below.
Please guide to resolve this issue.
Thank you.
Best Regards,
Amit.

Seems like you already have your conda environment loaded (as you can see the (base) on your command line prompt).
So you can just type python in the command line to get into the python REPL where you will be able to start using python command (like imports etc).
How to make it work from Default (base) commandline? Because I need to run TractSeg, which depends on pytorch. PFA TractSeg error log and help.
Thanks.

Amit.

Well pytorch seems properly installed in your main env. As you can see you can import it and use it.
But TrackSeg is a program. So you won’t be able to run that within python.
I don’t know what it is. Can you point to more information about it?
What is most likely happening is that it has a hardcoded version of python in there that is used instead of the conda one and pytorch is not available in that version of python.
You want to make sure that you installed this in the same environment as pytorch. Also this uses /usr/bin/env python which might not pick up the conda env
