math_code_test_d module in google colab for interactive math courses doesn't exist

I’ve found the article about there is almost done interactive math courses exists by FCC. There is in the post links to certain chapters of the course in google colab.

But when I try to run any code test it got me with an error like this one: No module named 'math_code_test_d'

Screenshot for example:

Any workaround here to fix that or maybe the course moved to another place?
