YOLO custom object detector single epoch training for 3 days

Question

I am trying to implement YOLO object custom object detector. I have downloaded 1000 images for train data and 100 images for validation data seperately in colab. The code is running perfectly, except collab notebook takes almost one day to get single epoch.Below is the sample code. Also how can i use custom Human hand dataset of google open image like kaggle without downloading it on collab.
