I made some test and it is an OSX problem only with Python 3.7
It works well with Python 3.6
$ conda create -n pythran python=3.6
$ conda activate pythran
$ conda install -yq ipython matplotlib pythran -c conda-forge
$ ipython

Hi Pierre,
It is a strange error, I don't have a Mac so I am not 100% sure. I followed
what you did on Linux
with a small variation:
In [1]: %matplotlib
Using matplotlib backend: TkAgg
And it works well. This is not a solution, but could you try a different
matplotlib backend
(https://matplotlib.org/tutorials/introductory/usage.html?#backends ;
<https://matplotlib.org/tutorials/introductory/usage.html?#backends>)?
Cheers,
Ashwin
