MetaLearning-TF2.0: Training with custom data gets stuck on the first iteration.

When i am trying to train a model with my custom data, it is stuck with the following output:

No previous checkpoint found!
0it [00:00, ?it/s]

It stays like this until i interrupt the training. I can also see that the GPU is in use but i don’t see anything else happening. Is it normal? As far as i know, i should be able to see some logs like accuracy, loss, epoch count etc.
