There is a bunch of very strange stuff in the hidden “metadata” parts of your notebook. It looks like some of the metadata that the grader depends on has been removed somehow. Have you been running it on some other platform like Colab? Or maybe on your local computer, instead of on the course website? Or using some external tools to edit the notebook? I don’t think it would be possible to make the changes I see using the course website.

My suggestion would be to do the “Get a Clean Copy” process that is documented on the DLS FAQ Thread and then carefully “copy/paste” over just your completed code from the “YOUR CODE HERE” segments and see if that helps.

There is also a bunch of added code and other changes you’ve made, e.g. the cells at the end where you import “pickle” and create some files. But I tried deleting those cells and it still fails the grader.

Please try the “get a clean copy” and let us know whether that helps or not.
