Strange error on unmatched ")"

Course Q&A Deep Learning Specialization Convolutional Neural Networks

I completed the assignment 2 (Alappaca) of Week 2 and all cells are working fine. However, when I submit to grader, I’m getting the strangest error. Here’s the text

Cell #UNQ_C2. Can't compile the student's code. Error: SyntaxError("unmatched ')'", ('/tmp/student_solution_cells/cell_16.py', 41, 5, '    )'))

If everything runs correctly for you, but fails the grader in that way, one possibility is that you did not do a “Save” before the “Submit” and the grader is seeing an older (and broken) version of your code.

Try this:

Kernel -> Restart and Clear Output
Cell -> Run All

Now scan through and make sure everything runs correctly. If so, then do this sequence:

Kernel -> Restart and Clear Output
Save
Submit Assignment

Let us know what happens.

For whatever reason, I think you are right. When I tried saving the code, it showed me this dialog. Looks like another session (I don’t know how) is opened somewhere trying to save my old code.

I did overwrite and then again Ran all cells to make sure, it’s all running smoothly. Doing that showed me that a new checkpoint was made for the notebook.

I’m still getting the same error. I really don’t know what to do to solve it. I’m literally stuck in my progress in this course due to this.

You seem to have had two copies of the notebook open in different browser windows. This confuses the Jupyter workspace manager.

You may deed to delete your notebook and start over.

I’ve seen the notebook and it turns out that the whole beginning section has just been deleted. Here’s what it looks like:

Why did you do that? It’s a mistake in general to modify things outside the “YOUR CODE HERE” segments. It’s not illegal, but you need to be careful when you do that. You must have trashed some of the JSON metadata that is not visible in the notebook, but which the grader depends on.

Please get a fresh copy and then copy over just your code from the “YOUR CODE HERE” segments and then try submitting to the grader again.

Please let us know if that resolves the problem for you.
