本文简要介绍python语言中 sklearn.metrics.ConfusionMatrixDisplay 的用法。 用法: class sklearn.metrics.ConfusionMatrixDisplay(confusion_matrix, *, display_labels=None) 混淆矩阵可视化。 建议使用 from_estimator 或from_predictions 创建ConfusionMatrixDisplay 。所有参数都存储为属性。 在用户指南中阅读更多信息。
FutureWarning: Function plot_confusion_matrix is deprecated; Function `plot_confusion_matrix` is deprecated in 1.0 and will be removed in 1.2. Use one of the class methods: ConfusionMatrixDisplay.from_predictions or ConfusionMatrixDisplay.from_estimator. warnings.warn(msg, category=FutureWarning) ...
