DLS C4W2 Error: "Looks like the BatchNormalization units are not working"

Hello everyone.
I was trying to do DLS C4W2 assignment, and I have been stuck on this for too long. I have even seen many solutions online and still can’t get it right.

You are using an older version of the notebook.
Here’s the new function signature:

# UNQ_C1
# GRADED FUNCTION: identity_block

def identity_block(X, f, filters, initializer=random_uniform):

Posting solution code in a public topic is discouraged and can get your account suspended. It’s okay to share stacktrace on a public post and send code to a mentor via direct message. Don’t forget to clean up the post.

Please explain why you are setting the training parameter only for BatchNormalization. The test code explicitly manages the learning state via tf.keras.backend.set_learning_phase(True) and tf.keras.backend.set_learning_phase(False)

Sorry sir. Must’ve been a brain-fade moment from my side.
Thank you so much. All my doubts have been solved and I’ve successfully completed the assignment.
