When I was running train.py, I got

Traceback (most recent call last):
  File "train.py", line 147, in <module>
    train()
  File "train.py", line 52, in train
    model_systole = get_model()

    model.compile(optimizer=adam, loss='rmse')

I did not change anything in the code, including the loss function.

RMSE loss function is removed in the newest version of Keras. I just updated the code to include RMSE as a custom loss function - check model.py.

Solved. Thanks!
