error at first start
Hi,
I just installed it and this is what I got at the launch (python3.6 -m nbmanager)

Sounds like it's getting a non-JSON response back when it expects JSON. You could stick a print(r.content) in the code just before it calls r.json() to see what data it's getting.
It's not getting JSON, but html. I have the same problem here on windows 10 and Python 3 (anaconda install)

Make sure you're using an up-to-date version from git - that HTML looks like it might be getting an older version which didn't send the authentication token.
Hi @takluyver , yes I confirm I am using latest version from master at e45dad3007
