You seem to have changed certain cells which should’ve been left untouched.
For instance, this is the original code for the assignment:

if not "accuracy" in hist.model.metrics_names:
    print("Use 'accuracy' as metric when compiling your model.")
else:
    print("The metric was correctly defined.")

You have:

if not 'acc' in hist.model.metrics_names:
    print("Use 'acc' as metric when compiling your model.")
else:
    print("The metric was correctly defined.")

Please don’t add / remove:

  1. Notebook cells
  2. print statements
  3. Function parameters
  4. Imports

Don’t:

  1. Rename functions / change return type
  2. Rename global variables

Fill your code where instructed, using local variables when possible.
I recommend you try again by following instructions in Refresh your Lab Workspace section in this link.

There were 2 issues:

  1. The notebook didn’t have the right metadata. So, the workspace had to be refreshed.
  2. The loss was incorrect.
