Your copy of the notebook is out-of date. There is a newer notebook since about two months ago.
You will also need the new version of the w1_unittest.py file.
Instructions for updating your notebook are in the “M4ML Resources FAQ” thread. You can find it by using the forum Search tool.
Also, in the future, please do not post your code on the forum. That’s not allowed by the Code of Conduct.
If a mentor needs to see your code, we’ll contact you with instructions.
You can post screen capture images that show any error messages or asserts. Those are very helpful.
