怎么解决cannot import name 'plot_confusion_matrix' from 'sklearn.metrics'

这个错误通常是因为scikit-learn的版本太低而导致的。你可以通过升级scikit-learn来解决这个问题。具体来说，可以使用以下命令升级scikit-learn:

pip install --upgrade scikit-learn

如果您已经安装了最新版本的scikit-learn，您还可以尝试卸载和重新安装scikit-learn来解决此问题:

pip uninstall scikit-learn
pip install scikit-learn

如果这些方法都没有解决您的问题，请检查您的代码是否正确导入了sklearn.metrics中的plot_confusion_matrix函数。您可以按如下方式导入sklearn.metrics中的plot_confusion_matrix函数:

from sklearn.metrics import plot_confusion_matrix

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name plot_confusion_matrix from sklearn.metrics" usually occurs when the version of scikit-learn you are using is outdated and does not support the plot_confusion_matrix function.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
print(sklearn.__version__)

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.

cannot import name 'plot_confusion_matrix' from 'sklearn.metrics'

The error message "cannot import name 'plot_confusion_matrix' from 'sklearn.metrics'" usually occurs when you are trying to use the "plot_confusion_matrix" function from the "sklearn.metrics" module but it is not available in your version of scikit-learn.

The "plot_confusion_matrix" function was added in scikit-learn version 0.22, so if you are using an older version of scikit-learn, you will need to upgrade to version 0.22 or higher to use this function.

To upgrade scikit-learn, you can use pip, the Python package installer, by running the following command in your terminal or command prompt:

pip install --upgrade scikit-learn

After upgrading scikit-learn, you should be able to import the "plot_confusion_matrix" function from the "sklearn.metrics" module without any issues.
