BUG: shap summary plot for 3 group classification

[myeonggyukim0513]

Issue Description

I ran the same code to reproduce the SHAP summary plot for the 3-group classification that I ran before. However, instead of the bar graph for the 3 groups, an interaction plot has been appearing for the past few days. Has there been any change in the source code?

Below is my code for SHAP plot.

explainer = shap.TreeExplainer(model) shap_values = explainer.shap_values(X) shap.summary_plot(shap_values, X, plot_type="bar", class_names=['Cat1', 'Cat2','NC+Cat3'], class_inds='original')

Previous result

Now,

Minimal Reproducible Example

explainer = shap.TreeExplainer(model)
shap_values = explainer.shap_values(X)
shap.summary_plot(shap_values, X, plot_type="bar", class_names=['Cat1', 'Cat2','NC+Cat3'], class_inds='original')

Traceback
