Word neutralize error

this error came from the ungraded part

I did not encounter that problem. The error message is pretty clear, don’t you think? One of the arguments to that cosine_similarity call is “None”. So how did that happen? Is there perhaps some code you did not fill in?

Note that this section is “optional”, which just means it is not graded. But that doesn’t mean you don’t have some code to write. Take a closer look at the “YOUR CODE HERE” sections in neutralize.

Indeed. If you leave an Optional section incomplete, the grader may not be happy. The behavior varies between courses.

True, I did not notice that there is some work to do, i did it and worked
sorry to bother you
