I have a problem:
I completed all the tasks, created the model, converted it to JSON, and uploaded all necessary files to Coucera.
The recommended version of TensorFlow 2.2 is not able to be installed in Colab by the provided code. Maybe here is the reason.
I need help understanding what I did wrong if I followed all the instructions.
The grading system needs to explain the reason.
All I see is: The model in your submission is invalid. Please try again!
