cannot import name 'plot_confusion_matrix' from 'sklearn.metrics' [图片]

这个错误通常是因为你的 Scikit-learn 版本太旧了。`plot_confusion_matrix` 是 Scikit-learn 0.22 版本中新增的 API，如果你的版本低于这个版本，就无法使用它。

你可以通过以下命令升级 Scikit-learn：

pip install --upgrade scikit-learn

如果你已经使用了虚拟环境，请确保在虚拟环境中执行上述命令。如果你没有使用虚拟环境，请使用管理员权限运行终端或 PowerShell 窗口，以确保升级的是全局环境中的 Scikit-learn。

cannot import name plot_confusion_matrix from sklearn.metrics

The error "cannot import name plot_confusion_matrix from sklearn.metrics" usually occurs when the version of scikit-learn you are using is outdated and does not support the plot_confusion_matrix function. This function was introduced in version 0.22, so you need to make sure you are using at least that version.

You can check the version of scikit-learn you are using with the following code:

import sklearn

If your version is lower than 0.22, you can upgrade it by running the following command in your terminal:

pip install --upgrade scikit-learn

Once you have upgraded scikit-learn, you should be able to import the plot_confusion_matrix function without any issues.
