UnpicklingError: invalid load key, '3'

Question

I am creating a chatbot. So, i need word2vec file in binary format. When i am loading bin file then i am getting this type of error.

import gensim

model = gensim.models.Word2Vec.load('GoogleNews-vectors-negative300.bin')

Traceback (most recent call last):

UnpicklingError: invalid load key, '3'.

If it is a binary file you need to mention it like this:

import gensim.models.keyedvectors as word2vec
model = word2vec.KeyedVectors.load_word2vec_format('GoogleNews-vectors-negative300.bin', binary=True)
