Expected Behavior

Running d01 on TIGRE for Python in a nightly build of 12/11.

Actual Behavior

An Expection was thrown, the traceback as follows:

Code to reproduce the problem (If applicable)

d01.
Tried matplotlib versions of 3.8, 3.7 and 3.6. None worked.

Specifications

• MATLAB/python version: 3.11
• OS: Ubuntu 22.04 LTS
• CUDA version: 12.2

Hi @ChemEng227 , I have not changed anything in TIGRE plotting in months, so something else in your nightly must have changed. You say that its not matplotlib, but must be something else then.

It looks like it has to do with the graphic engine being used. Can you let me know which matplotlib renderer does your system use?

matplotlib.get_backend() returns 'QtAgg' in my environment.

[AnderBiguri]

Thanks! AFAIK QtAgg should support this, so I am not sure what is going on. I will try to investigate but its hard without being able to reproduce it. I would suggest not running d01 in your builds for now, in particular plot_geometry is not a critical function to use TIGRE.

same problem.

[reginaoli]

Hello! I had the same problem. But the error disappeared when I wrote in the beginning of the script these lines: import matplotlib matplotlib.use('QtAgg') However, the figure freezes and it does not appear. Anyone can help me overcome this problem? Thank you in advance!

[AnderBiguri]

@reginaoli can you tell me more about which machine are you running this on?

[reginaoli]

So, I changed the code editor (from spyder to vscode) and upgraded the versions of all the libraries and I can see the plots and graphics now. Thanks!!
