Import GoogleNews-vectors-negative300.bin

I am working on code using the gensim and having a tough time troubleshooting a ValueError within my code. I finally was able to zip GoogleNews-vectors-negative300.bin.gz file so I could implement it in my model. I also tried gzip which the results were unsuccessful. The error in the code occurs in the last line. I would like to know what can be done to fix the error. Is there any workarounds? Finally, is there a website that I could reference?

Thank you respectfully for your assistance!

The below commands work.

brew install wget
wget -c ""

This downloads the GZIP compressed file that you can uncompress using:

gzip -d GoogleNews-vectors-negative300.bin.gz

You can then use the below command to get wordVector.

from gensim import models
w = models.KeyedVectors.load_word2vec_format( '../GoogleNews-vectors-negative300.bin', binary=True)

you have to write the complete path.

use this path:

try this -

import gensim.downloader as api
wv = api.load('word2vec-google-news-300')
vec_king = wv['king']

Here is what worked for me. I loaded a part of the model and not the entire model as it's huge.

!pip install wget
import wget
url = '
filename = wget.download(url)
f_in = gzip.open('GoogleNews-vectors-negative300.bin.gz', 'rb')
f_out = open('GoogleNews-vectors-negative300.bin', 'wb')
f_out.writelines(f_in)
import gensim
from gensim.models import Word2Vec, KeyedVectors
from sklearn.decomposition import PCA
model = KeyedVectors.load_word2vec_format('GoogleNews-vectors-negative300.bin', binary=True, limit=100000)
