After sending my assignment I have the the following evaluation in return:
Code Cell UNQ_C3: Function ‘unet_model’ is incorrect. Check implementation.
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors
But Code Cell UNQ_C3 passed the test well in the code. Could it be an error in evaluation?
