图片[1]-Error in confusionMatrix,default(as.factor(y pred label)reference = as.factorly label): The data must contain some levels that overlap the reference…-决策链社区论坛

【报错原因】

DCA绘图里：
y_pred_label <- as.numeric(y_pred_score > thresh)
cm <- confusionMatrix(as.factor(y_pred_label), reference = as.factor(y_label))$table

【解决方法】

这样必须是0-1标签了，字符串类别出现问题
