Hi there forlks, just installed plotly python on Ubuntu 15.10

i’ve installed numpy and of course installed plotly via pip
my current plotly version is 1.12.9 , if I print on screen pip show plotly. The problem is that when I try to import plotly via python i gets this error:

python

Someone has any idea what is going on? Just can get out of this !! I even cannot log in with my API key!

Seems to have resolved the issuee after hours of head hacheee!!
The problem was in a file .local/lib/python2.7/site-packages/requests/packages/urllib3/contrib/pyopenssl.py
i changed permission to all the folder, and change the line 171 in the file, substituting extension with Extensions
now seems to import plotly, i’ll tell you if it is gonna work! :slight_smile:

EDIT:
Nope… this seems not to work!! Why it has just worked feww minutes ago, and now is not going!! :S

Finally maneged to resolve completely the issue.
The problem was with the python module cryptography, which was not updated.

just typed:

sudo pip install cryptography --update

and worked! :smiley:
