# GRADED FUNCTION: preprocess_dataset

[Deepti_Prasad]

Hi @mallen

As you mentioned you have passed the previous unittest cell, I am only sharing solution for the grade cell you are currently having issue. In case it throws again any error after the correction than the previous grade cell codes need to be looked upon, let me know if that happens.

For now please refer the below comment(remember the max length is passed upon in the previous grade cell vectorizer code, that’s why I asked if your previous unittest cell passed or not) Max length code writing is not part of the preprocess data

C3W2 Expected output

In the preprocess data, basically there are 3 call arguments already assigned for this grade cell. one is dataset for you to preprocess next text_vectorizer which is function recall to convert your text data into vector and lastly label_encoder which you recalled in the previous grade cell will be used to encode data labels here in this cell, preparing your preprocess data to be model trained. You need to define this in single code line using map keys( ) to the argument dataset. Hope this r…
