C3W1_Assignment: Submission result problem

I am getting above error after submitting the valid h5 file for Week-1 Assignment of course Advance computer vision with tensorflow.

I have cross validated and load the model file and it’s loading & working properly.

This happens when you did not build model. Please check whether the model is built or not.

I was having the same problem. I was using tf.keras.optimizers.experimental.SGD instead of tf.keras.optimizers.SGD, apparently it raises issues with the grading mechanism.
