Running on Jetpack #1944

Hi, I saw people back in Sep 2020 able to use python3.6 and torch 1.6 to run YOLOv5 on Jetpack(Linux18.04). I have issues in installing torch 1.7 to Jetpack with python3.8. I wonder if I can use two other ways:

1. use an older version of YOLOv5 with python3.6+torch1.7, which I have successfully installed but failed the YOLOv5 requirements installation.
2. try another combination - torch1.8 and python3.8 as someone claimed a success.

Does anyone know if it is possible to get an older version of YOLOv5 or prove that torch1.8 works? Thanks!
