Continue training model on new data

[mansi-aggarwal-2504]

Hello!
I have a fully trained model (75 epochs) on a certain dataset and I tested it on another dataset. I now want to further train my model on this test dataset. Should I just run:

python train_step1.py --weights 'path/to/best_75_epochs.pt' (Or should the training be continued using last.pt?)

Can I run this on fewer epochs or should it be the same as best.pt? And will this new model be considered to be trained with 75 epochs + new training epochs or just new training epochs on new data?

Also, train_step2.py will then use this new model's last.pt weights, right?

Thanks!
