Help! Error in Submitting My code

I completed week 1’s assignment, including the optional part but for some reason my submission received a grand total of ZERO points, with the following error message:

“Sorry, your submission was incorrect. Please try again. Invalid control character at: line 391 column 15 (char 16384)”

I have no idea how to fix this problem. Which line number is being referred to? How do I get to
char 16384.

Thanks for your help on this!

My guess is that this means your notebook is corrupted in some way. Did you use any external tools other than the course website to modify the notebook?

The first thing to try would be to get a clean copy of the notebook and then carefully “copy/paste” over just your completed lines of code from the “YOUR CODE HERE” sections. Here’s a DLS thread with instructions for how to get a clean copy. The instructions are generic and will work for GANs notebook as well.
