Hi team I am using python 3.6.6 in windows 10 os (64 bit version). I am able to successfully install snips_nlu using pip but downloading en laguage package is causing openssl failure. Here is the complete stack trace :

Could you create a new virtualenv, pip install pyopenssl requests inside it, and then run python -c "import requests;data = requests.get('https://raw.githubusercontent.com/rc0r/afl-fuzz/master/dictionaries/jpeg.dict');print(data.content)" and see if that works? I did this on a Windows machine just now and it worked fine.

I tried this but it didn't work, I got the same error.

Unfortunately, to be able to help further we'll need a way to reproduce it locally.
