Training and Prediction command

 # train your custom detector! (uncomment %%capture below if you run into memory issues or your Colab is crashing)
 # %%capture
 └── !./darknet detector train training/obj.data training/yolov4-tiny.cfg training/yolov4-tiny.conv.29  -dont_show -map
 
 # run your custom detector with this command (upload an image to your google drive to test, thresh flag sets accuracy that detection must be in order to show it)
