What version of requests do you have installed?

[raphadasilva]

I've just checked : 2.4.3 for Python 3 (I just tested the previous code with this Python version) and requests 2.12.1 for Python 2 !

[gboeing]

Make sure you have the most recent version of requests in both environments, with: pip install requests --upgrade

[raphadasilva]

Yes, I've got the most recent version on Python 3.4 available with pip --upgrade ! It's always 2.4.3, no changes.

For Python 2.7 upgrade didn't work, but I didn't use it for these particular case.

[gboeing]

Ok. Try upgrading OSMnx to its latest beta version: 0.1b2:

pip install osmnx --upgrade --pre

I added a new piece of code that should let it work with old versions of requests, include v2.4.x.

[raphadasilva]

That's nice, thank you very much !

I used also sudo pip3 install --ignore-installed requests command, because I found an "owed by OS" message very strange.

By curiosity, which requests version do you have ? I'm quite sure that 2.4.3 is the most recent on my system !

Now I've got OSMnx 0.1b2 version (just checked it), so I ran the same command but... new error :-/...

Do you prefer that I open a new issue with that and close this one ?

Thank you again for your time and advices !

[gboeing]

I'm using requests 2.12.1 in both my Python (3.5 and 2.7) environments.

Regarding the NetworkXPointlessConcept, there's an open issue for that right now: #8. Would you comment on that issue with your details as I'm working on it there?
