Assigned workbook working perfect - passing all test unittest events , all results as expected such as stop at third epoch reaching 98% .
BUT submitting file ) I’ve submitted it 7 times always same 0 score of 100 - so nothing was accepted. but error log appears randomly on one of all three stage
create_and_compile_model
EarlyStoppingCallback
training_history
Submitted files was the same , I am sure it saved before supplied checking since second attempt. Restarted kernel and re-run each code couple times. nothing help
If that doesn’t help, please ensure that no global variables are used unless necessary. If grader still fails your submission, click my name and message your notebook as an attachment.
Please fix the function train_mnist using this hint in the notebook:
# Create a compiled (but untrained) version of the model
# Hint: Remember you already coded a function that does this!
Do not use the global variable untrained_model directly in the function as indicated in the hint. Invoke the function that creates and returns the model for you. Just made that change on your notebook and tried at my end. The grader awarded full score.
