I am using CoLab Pro for few days. I was trying to Train a Deep Learning Model using TPU Runtime in CoLab Pro. But the Runtime is getting automatically disconnected after 12 hours of Training. I have configured 70 epochs for Training and it stops at around 43 - 52 epochs. I have used Keras/Tensorflow for developing my model. For the last three days I am Training the same model but I am no able to complete the Training Process. It is frustrating that even after opting for CoLab Pro, we are not able to train the model fully.
