Model failed to draw due to matplotlib issue

[alicia-krause]

Hi!

First time running GADMA and I've been able to succesfully run the model. However, I'm getting the message 'failed to draw model due to the following exception: module 'matplotlib.cbook' has no attribute 'MatplotlibDeprecationWaring." My advisor and I believe this could be due to recent updates in matplotlib due to some community posts we've been seeing about other modeling programs having issues with recent matplotlib updates. For reference I'm running gadma ver. 2.0.3 and matplotlib 3.7.2. At completion I'm able to get the AFS plots but not the blue demographic model plot.

In hopes of trouble shooting this my advisor and I tried running an older matplotlib ver. 3.6.3 with gadma 2.0.3 but we are running into a new coding issue message: "Error occurred during caching: MaskedArray.array_wrap() takes from 2 to 3 positional arguments but 4 were given. Got vector [] of type <class 'gadma.utils.utils.WeightedMetaArray'>. Please, send this warning to ekaterina.e.noskova@gmail.com."

Any advice or troubleshooting help is appreciated!

Looking at past issues now and I'm going to try out 'pip install "matplotlib<=3.7.5"' which previously was used to fix this issue. Thanks!

Hi @alicia-krause,

Thank you very much for your feedback! You are absolutely right: the last versions of matplotlib cause matplotlib.cbook error. You need to install the following version to avoid the error:

pip install "matplotlib<=3.7.5"

Regarding the second error about MaskedArray. Unfortunately, that is a recent error that I am aware and plan to fix it in the next GADMA update. That error is due to the latest versions of moments package. I recommend to use moments 1.3.1:

pip install moments-popgen==1.3.1

That should solve the issue.

Best,
Ekaterina

Hi Ekaterina,

Thanks for your help. I'm now working with matplotlib ver. 3.7.5 and gadma is still coming back with an error saying that grid_b is not recognized (hopefully this isn't a case of inexperience on my end for troubleshooting).

Hi @alicia-krause,

If you try to draw model using moments (I think grid_b error is for that), then you need even older version of matplotlib as moments was not updated for newer releases. I would try to install "matplotlib<3.5". Hope that help!

Best,
Ekaterina
