thank you for the effort.

not sure if its my fault, but i kept getting random errors during first run like

LookupError: ***********************************

  Resource stopwords not found.
  Please use the NLTK Downloader to obtain the resource:

  >>> import nltk
  >>> nltk.download('stopwords')

---

the fix is quite easy, just need to go into python repl and execute those.

after downloading the requisite resources, it works fine!
