I also encountered the same issue and found a workaround for this. I'm using Python 3.6 on Mac and here are the steps for Mac users to eliminate the error:

1. Open /Applications/Python 3.6.
2. Double-click "Install Certificates.command".

(See: Mac OSX python ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749))

It seems that the cause of the issue is not pynlpir but Python itself. Python 3.6 on Mac no longer uses the system's trusted certificate, so when pynlpir tries to download the latest license through HTTPS, Python cannot establish a secure connection over TLS/SSL and fails as a result (See: Tell HN: Python 3.6 on OS X requires a post-install step for SSL to work | Hacker News).

I think this fact should be noted in README.

Hope this helps :)
