How to use GloVe word-embeddings file on Google colaboratory

Question

I have downloaded the data with wget

!wget http://nlp.stanford.edu/data/glove.6B.zip
 - ‘glove.6B.zip’ saved [862182613/862182613]

It is saved as zip and I would like to use glove.6B.300d.txt file from the zip file. What I want to achieve is :

embeddings_index = {}
with io.open('glove.6B.300d.txt', encoding='utf8') as f:
    for line in f:
        values = line.split()
        word = values[0]
        coefs = np.asarray(values[1:],dtype='float32')
        embeddings_index[word] = coefs

Of course I am having this error:

IOErrorTraceback (most recent call last)
<ipython-input-47-d07cafc85c1c> in <module>()
      1 embeddings_index = {}
----> 2 with io.open('glove.6B.300d.txt', encoding='utf8') as f:
      3     for line in f:
      4         values = line.split()
      5         word = values[0]

IOError: [Errno 2] No such file or directory: 'glove.6B.300d.txt'

How can I unzip and use that file in my code above on Google colab?

Answer 1

One more way you could do is as follows.

1. Download the zip file

!wget http://nlp.stanford.edu/data/glove.6B.zip

post downloading the zip file it is saved in the /content directory of google Collab.

2. Unzip it

!unzip glove*.zip

3. Get the exact path of where the embedding vectors are extracted using

!ls
!pwd

4. Index the vectors

print('Indexing word vectors.')

embeddings_index = {}
f = open('glove.6B.100d.txt', encoding='utf-8')
for line in f:
    values = line.split()
    word = values[0]
    coefs = np.asarray(values[1:], dtype='float32')
    embeddings_index[word] = coefs
f.close()

print('Found %s word vectors.' % len(embeddings_index))

5. Fuse with google - drive

!pip install --upgrade pip
!pip install -U -q pydrive
!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null

!apt-get -y install -qq google-drive-ocamlfuse fuse

from google.colab import auth
auth.authenticate_user()
# Generate creds for the Drive FUSE library.
from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()
import getpass
!google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass()
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}

!mkdir -p drive
!google-drive-ocamlfuse drive

6. Save the indexed vectors to google drive for re-use

import pickle
pickle.dump({'embeddings_index' : embeddings_index } , open('drive/path/to/your/file/location', 'wb'))

If you have already downloaded the zip file in the local system, just extract it and upload the required dimension file to google drive -> fuse gdrive -> give the appropriate path and then use it / make an index of it, etc.

also, another way would be if already downloaded in the local system via code in collab

from google.colab import files
files.upload()

select the file and use it as in step 3 onwards.

This is how you can work with glove word embedding in google collaboratory. hope it helps.
