hi there.

Thank you for the great package. However when I try to run it I get a bunch of errors like that:

[nltk_data] Error loading punkt: <urlopen error [SSL:
[nltk_data] CERTIFICATE_VERIFY_FAILED] certificate verify failed:
[nltk_data] unable to get local issuer certificate (_ssl.c:1076)>

Hi @chapkovski,
Are you running it on Mac OS? Does this comment help? https://github.com/nltk/nltk/issues/2029#issuecomment-392426356
