Error on using info command of MontePython to analyse chains

[nouicer]

I am facing an strange issue while using info to produce analyzes and plots of my txt outputs.
I suspected that it was the version of numpy that was not the right one (because of "normed" and "density" for the histograms). But I couldn't find a solution. Here is my error message and hope someone can help me.

Thank you so much

Dear user,
Your are raising issues on the old MontePython v1 and v2 repository (active in 2013-2018).
As clearly stated on this wiki, issue #55: since April 2018 and v3, the MontePython repository has moved to https://github.com/brinckmann/montepython_public
Please go there to clone a recent, working and maintained version of the code. Then, if necessary, please raise your issues in that repository.
(In this particular case, you are re-raising issue brinckmann#318 . This has been fixed on the devel branch and will be pushed public in the next version, in the meantime the issue provides the solution: anywhere in analyze.py where 'normed' is used for histogram or histogram2d it should use 'density' instead)
Best,
Thejs
