Can you please tell me why i am getting this error .

I fixed this error by following the suggestions made by @Roggu92 in #42 (comment) - The TL;DR is that I needed the weight files and I was essentially able to remove all version from YOLOv4/requirements.txt

I also had the error return temporarily due to poor lighting.
