Modelicares import fails in python

December 19, 2022

I want to use Modelicares to open my Dymola results in python but the import fails.

from modelicares.simres import SimRes

Gives the following error:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: cannot import name 'iterable' from 'matplotlib.cbook' (C:\ProgramData\Miniforge3\envs\main\lib\site-packages\matplotlib\cbook\__init__.py)

I tried DyMat and Buildingspy but I would prefer to use Modelicares. Because Buildingspy makes use of DyMat which is quiet old and seems unmaintained.

>Solution :

I also had this issue.

I fixed this in my fork of modelicares here: https://github.com/sede-fa/ModelicaRes

I basically replaced any reference to matplotlib.cbook to numpy to get the iterable function as shown here: https://github.com/kdavies4/ModelicaRes/issues/42

You can install this via pip by doing: pip install git+https://github.com/sede-fa/ModelicaRes.git
