We are using custom Ubuntu 20.04 and we just need a couple update in Jetson Nano for YOLOv5.
git clone https://github.com/ultralytics/yolov5.git
the custom ubuntu has a custom library too, so we just need some small tunning to run YOLOv5
copy and paste the custom req file to requirements.txt in YOLOv5 default folder.
pip3 install -r requirements.txt
after the installation completed, the check the detect.py
go to /krti/yolov5
python3 detect.py --weights yolov5s.pt --source 0
