If you’re a frequent user of spacy and virtualenv you might well be all too familiar with the following:

<blockquote class="wp-block-quote">

If you&#8217;re lucky and you have a decent internet connection then great, if not it&#8217;s time to make a cup of tea.

Even if your internet connection is good. Did you ever stop to look at how much disk space your python virtual environments were using up? I recently found that about 40GB of disk space on my laptop was being used by spacy models I&#8217;d downloaded and forgotten about.

Fear not &#8211; spacy link offers you salvation from this wasteful use of disk space.

Spacy link essentially allows you to link your virtualenv copy of spacy to a copy of the model you already downloaded. Say you installed your desired spacy model to your global python3 installation &#8211; somewhere like** _/usr/lib/python3/site-packages/spacy/data_**** __**

Spacy link will let you link your existing model into a virtualenv to save redownloading (and using extra disk space). From your virtualenv you can do:

python -m spacy link ** _/usr/lib/python3/site-packages/spacy/data/<name\_of\_model> <name of model>_**

For example if we wanted to make the **en\_core\_web_lg** the default english model model in our virtualenv we could do 

python -m spacy link ** _/usr/lib/python3/site-packages/spacy/data/en\_core\_web_lg en_**

Presto! Now when we do **spacy.load(&#8216;en&#8217;)** inside our virtualenv we get the large model!
