Course 4 - w3a2: Code Cell UNQ_C3 Error

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?

Thanks

Hi mpsica,

That your code passes the tests in the notebook does not ensure it will pass the final grader. The test cases used in the notebook are not comprehensive.

So I would suggest to try to find an issue in your implementation. If that does not work out, and you cannot find any useful comments in the discourse forum, feel free to ask again. Good luck!
