C4W2 Exercise Submission Fail. "An unexpected error occurred. Please try again later"

[sekanti02]

I am submitting the C4W2 assignment however I don’t get any particular feedback for any exercise.

• I can run each exercise successfully in the unit test code cells.
• I have restarted the kernel and run every cell one by one to the end by saving models and variables etc.
• Because I am following the course on deeplearning.ai website(not coursera), I could not try the option where you could restart the exercise sheet.

I don’t know what else to try.

Please help!!

Sorry, the course is pretty new on the DLAI platform and I have never seen that particular syndrome from the grader. I’ll need to look at your notebook. We can’t do that on a public thread, but please check your DMs for a message from me about how to proceed.
