{edited by mentor}
but the code works perfectly fine

Hello, @Yashjhota,

If you could run the 16th cell without any error reported, it could be that the autograder was looking at an earlier version of your assignment. I suggest you to try the notebook’s save button and then make another submission.

Cheers,
Raymond

PS: we shouldn’t share our work publicly, but please don’t worry as I am going to remove it for you.

Note that you cannot grade a notebook that has been renamed.

Here’s the template code that was given to you in alpaca_model:

base_model = tf.keras.applications.MobileNetV2(input_shape=None,
                                                   include_top=None, # <== Important!!!!
                                                   weights=base_model_path)

When you filled in the required parts, you also changed the close paren to be the equivalent of this (without your other changes):

base_model = tf.keras.applications.MobileNetV2(input_shape=None,
                                                   include_top=None, # <== Important!!!!
                                                   weights=base_model_path
)

That is legal python syntax, but it confuses the grader for some reason.

Also note that you added a bunch of unnecessary “import” statements. I don’t think those cause any problems, but they are a mistake. If something shows as not imported, that means you forgot to run the earlier cells in the notebook. You need to do that every time you restart or reopen the notebook.

@rmwkwok

If you could run the 16th cell without any error reported,

Note that the cell numbers in the grader feedback typically do not refer to the student’s notebook. They refer to a notebook that the grader uses to test the learner’s code.

[TMosh]

For the record, recently another student had a similar issue with this assignment. In that case it was due to the single ‘)’ being indented to align below the function parameters.

In that case, the error was regarding “unexpected indent”, instead of “unmatched )”.

It appears the grader does not correctly handle a close-paren that is preceded by whitespace.

Sir Very Very Thanks for helping me so smartly
