embeddings 0.0.8

Installation

pip install embeddings  # from pypi
pip install git+https://github.com/vzhong/embeddings.git  # from github

Usage

Upon first use, the embeddings are first downloaded to disk in the form of a SQLite database. This may take a long time for large embeddings such as GloVe. Further usage of the embeddings are directly queried against the database. Embedding databases are stored in the $EMBEDDINGS_ROOT directory (defaults to ~/.embeddings). Note that this location is probably undesirable if your home directory is on NFS, as it would slow down database queries significantly.

from embeddings import GloveEmbedding, FastTextEmbedding, KazumaCharEmbedding, ConcatEmbedding

g = GloveEmbedding('common_crawl_840', d_emb=300, show_progress=True)
f = FastTextEmbedding()
k = KazumaCharEmbedding()
c = ConcatEmbedding([g, f, k])
for w in ['canada', 'vancouver', 'toronto']:
    print('embedding {}'.format(w))
    print(g.emb(w))
    print(f.emb(w))
    print(k.emb(w))
    print(c.emb(w))

Docker

If you use Docker, an image prepopulated with the Common Crawl 840 GloVe embeddings and Kazuma Hashimoto’s character ngram embeddings is available at vzhong/embeddings. To mount volumes from this container, set $EMBEDDINGS_ROOT in your container to /opt/embeddings.

For example:

docker run --volumes-from vzhong/embeddings -e EMBEDDINGS_ROOT='/opt/embeddings' myimage python train.py
