Looks like some of the words or token do not have a value in word2idx

Use dict.get to prevent the error.

Ex:

X = [[word2idx.get(token, None) for token in d.split()] for d in desc]

Some of the token or words are not in the dictionary you are looking for. Ex the key `for` is not in dict `word2idx` – Rakesh Apr 13 '18 at 10:16
