这个问题通常是由于sklearn版本不兼容导致的。您可以尝试更新sklearn版本或者使用其他版本的sklearn。如果您已经更新了sklearn版本但仍然遇到此问题,则可能需要卸载并重新安装sklearn。以下是解决此问题的步骤:
1.卸载sklearn:
```shell
pip uninstall scikit-learn
```
2.重新安装sklearn:
```shell
pip install -U scikit-learn
```
3.如果您仍然遇到问题,请尝试使用conda安装sklearn:
```shell
conda install scikit-learn
```
4.如果您仍然遇到问题,请尝试手动安装plot_confusion_matrix:
```shell
pip install matplotlib
pip install scikit-learn==0.22.2.post1
```
请注意,这里的版本号是0.22.2.post1,您可以根据您的实际情况进行更改。

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name plot_confusion_matrix from sklearn.metrics" usually occurs when the version of scikit-learn you are using is outdated and does not support the plot_confusion_matrix function.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