Testing cell not working (C1W3)

Hi, I found the first testing cell is not working , and it only shows " Reload the images in case you run this cell multiple times" I tried to reload the images and run the program from the beginning again, but it did not work.

Could someone help me with it?

Please update your post with stacktrace of the error.

Hi! Thanks for the reply. I just figured it out. I can choose to show the code. And it is good now.
