c3Week3 fit_vectorizer gives AttributeError: 'NoneType' object has no attribute 'vocabulary_size

please post screenshot of the error without posting any grade cell codes. Also confirm if your query is from week 3 or week 2 the fit vectorizer required one to instantiate tokenizer class using TextVectorization function and use the standardize as well as assign MAX_LEN(max length) to the output sequence length, to make sure when the vectorizer was adapt to fit the sentences, the desired vocabulary size is selected.

remember when test result which you have got shows a different results than the expected, chances are that you might have used global variables instead of local variables.

Also remember you are only suppose to right codes as per instructions already given to you and not hard code the other to recall functions.
