Great tutorial, thanks!

Not sure why I'm getting the following error, working on macOS with Jupyter Lab, Python 2.7 and Spacy 2.0.9:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-2-090b6e832a74> in <module>()
      3 # It creates a list of unique words in the text
      4 tokens = list(set([w.text for w in doc if w.is_alpha]))
----> 5 print nlp.vocab['cheese'].vector

lexeme.pyx in spacy.lexeme.Lexeme.vector.__get__()

ValueError: Word vectors set to length 0. This may be because you don't have a model installed or loaded, or because your model doesn't include word vectors. For more info, see the documentation:

I was getting the same error. I fixed it by downloading a different language model for spaCy than what the instructions indicated (one that includes vectors). See spaCy documentation here: https://spacy.io/usage/models

So instead of running this from the command line:
python -m spacy download en
. . . and using this command in Jupyter:
nlp = spacy.load('en')

I ran this command in bash:
python -m spacy download en_core_web_md
. . . and did this in Jupyter
nlp = spacy.load('en_core_web_md')

Hope this helps!
