How to build calibration curve for multiclass ML model?

[Akhmetzhan]

Hi David,
I am struggling with plotting a reliablity (calibration) curve for my machine learning model. I have searched Internat for multiclass model calibration, and it seems only your package can help me with my issue. I am novel Python user. Please could you provide an example Python code (notebook) for plotting calibration curve with your package?
Great thanks in advance
Sincerely, Akhmetzhan
