The wordnet lemmetizer is not working. I have tried a few words to get their base forms, but instead I am getting the words themselves without conversion to base form. I have tried installing wordnet both from pip and nltk downloader.
WordNer Lemmetizer not working
Hey @SanchitSayala, it is not necessary that these lemmatizers always give you good results. There are shortcomings of every model in ML. I request you to go through this once :
Stemming and Lemmatization Examples with code.
Check if your model lemmatizes some of the examples in this blog above.
I hope this helps ! 
Happy Learning !
