shap：SystemError：_internal 的初始化失败但未引发异常

Question

我正在使用 SVC 来预测目标。我正在尝试使用 shap 来获取功能重要性。但它失败了。

这是我从 shap 的官方文档复制的简单代码：

import shap
svc_linear = SVC(C=1.2, probability=True)
svc_linear.fit(X_train, Y_train)
explainer = shap.KernelExplainer(svc_linear.predict_proba, X_train)
shap_values = explainer.shap_values(X_test)
shap.force_plot(explainer.expected_value[0], shap_values[0], X_test)

但我明白了：

我不知道为什么？有谁知道为什么？

根据 Hiran 在问题中的评论，它也对我有用。 卸载后重新安装 shap。

pip 卸载 shap

pip 安装 shap
