Setup help required

Hi, I have made an object detection model using Yolov5 and tested it on my laptop all is working fine. Now I need to run its detect.py file on orange pi lite (ubuntu 16.04) as my input for the trained model is a USB cam attached to orange pi.

I need help running it on the orange pi as I have installed python 3.7 on it but there are a few errors coming while installing Pytorch and all given the os or the orange pi version. SO basically need help running it.
