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name plot_confusion_matrix from sklearn.metrics" usually occurs when the version of scikit-learn you are using is outdated and does not support the plot_confusion_matrix function.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