Why cant i extract all vocabs?
Make sure that you follow the instructions and implement them accurately. For further help, you need to share your code with mentors (in private messages, not here!). However, try debugging your code first to find the problem yourself!
Hope it helps! Feel free to ask if you need further assistance.
Your code for Get the Vocabulary is incorrect.
Use get_vocabulary( ) function key to the sentence_vectorizer to get the right vocabulary.
