title: Training on Google Colab Pro+ halted before completing all the epochs
body: <p>I was trying to train the YOLOv5x6 model with 300 epochs on a Google Pro+ instance. Unfortunately, after running for almost 20+ hours, the training halted at 250th epoch without indicating any error/information/warning. Any idea what went wrong? Before giving another try, I'd like to know what could have caused this issue. Is there a way to continue the training from where it left off?</p>
