I am running a virtual environment with python3.8. So when i call python, it’s actually runnin python3.8.

OK gotcha - here is a topic about building PyTorch for Python 3.8 that may be helpful:

Install PyTorch with Python 3.8 on Jetpack 4.4.1

Hey @dusty_nv, thank you for your quick response. With your help I was able to build PyTorch 1.7 for Python 3.8 on Jetpack 4.4.1 (Jetson Xavier). It actually helped to switch to the 1.7 branch of PyTorch. Here are the steps that worked for me: Easiest way: git clone --recursive --branch 1.7 http://github.com/pytorch/pytorch cd pytorch python3.8 -m pip install -r requirements.txt python3.8 setup.py install From where I was coming: git clone https://github.com/pytorch/pytorch.git cd pytorch gi…

But the issue is, some of the packages installed, downloaded and upgraded via these commands may cause my usb interfaces to stop working.
