Example of "Plot Pair" contours

[MCruzReyes]

I'm trying to reproduce this example plot given on the GitHub

The code is made to plot confidence contours, however if I copy and paste the code in my computer I get the following error:

ArviZ version: 0.11.2
matplotlib version: 3.4.2

Maybe i'm using an old version of arviz?

Can you install latest github version

pip install git+https://github.com/arviz-devs/arviz

We are working for a new release in a near future.

@ ahartikainen I already installed the latest github version, however I get the same error.

I am using Python 3.7.11

[ahartikainen]

Are you sure that the code is run on latest github version?

If on jupyter, remember to restart the notebook. Also could it be that pip is referring to some other python?

Easiest way to fix this is to call pip with python

python -m pip install git+https://github.com/arviz-devs/arviz

Now is working, maybe I was referring to other python version, thank you for your help.
