I am encountering a compatibility issue between the SHAP (SHapley Additive exPlanations) library and NumPy in my Python environment. The issue arises when I attempt to use SHAP to compute SHAP values for my machine learning model.
When I execute the following code:
import shap
explainer = shap.TreeExplainer(rf_classifier)
shap_values = explainer.shap_values(X_test)
shap.summary_plot(shap_values, X_test)
I encounter the following error:
TypeError: 'numpy._DTypeMeta' object is not subscriptable
The error message seems to be related to the shap.utils module and the NumPyArrayGeneric variable.
I have reinstalled SHAP to ensure a clean installation, which installed a version of NumPy. I have verified the compatibility of SHAP and NumPy versions, but I'm still encountering this error.
SHAP version: 0.44.1
NumPy version: 0.22 (I believe)
