The Autograder gave me 0 , Despite passing all the tests in the notebook .
Passing the unit tests does not prove that your code is perfect. The grader contains other unique tests that are not in the notebook.
Note also that you can’t grade an incomplete notebook - you must complete all of the assignment (and replacing any “None” statements as instructed) before it can be graded.
i’ve solved the problem .
Actually , the only thing I have changed is in the GRU layer , instead of passing 128 as positional argument , i passed it as keyword argument . then i submitted it , and got the correct grading .
