I don’t think it’s a good idea to work on a course notebook on Colab and then upload it back onto the course website. We have seen instances in which Colab rewrites some of the invisible “metadata” in the JSON files that are the notebooks in such a way that it no longer works with the Coursera graders.

My suggestion would be that you start with a clean copy of the notebook on the course website and then “copy/paste” over just your code from the “YOUR CODE HERE” sections from the uploaded Colab version and see if that helps. The point being that doing that would get you back to the Coursera version of the “metadata” in the notebook.

There is a topic on the DLS FAQ Thread about how to get a fresh copy.

Please try that and let us know what happens.
