WebSep 25, 2024 · Yep the problem was with third party optimizer. When I used keras' optimizer, then my training is working properly. Thanks a lot for the advice. I guess Hugging Faces' create_optimizer does not support apply gradient method for now. I will add this issue to their forum. Thanks a lot once again. dash system exit 1

Web2 days ago · My issue is that training takes up all the time allowed by Google Colab in runtime. This is mostly due to the first epoch. The last time I tried to train the model the first epoch took 13,522 seconds to complete (3.75 hours), however every subsequent epoch took 200 seconds or less to complete. Below is the training code in question.
