Problem with assignment Residual_Networks - convolutional-neural-networks- " identity_block" function

It looks like you have a very old version of the notebook. Did you copy it from github or from someone else? It hasn’t looked like that on the course website for at least a year. Copying someone else’s work is a) cheating and b) doesn’t work if the version you are copying is not recent.

There should be no “training” parameter visible anywhere in the identity_block or convolutional_block APIs.

My suggestion is to get a clean copy of the notebook and start over.
