CategoricalNB should be present from Scikit-learn 0.22. If that is installed (check sklearn.__version__), then you’ve confused your environments or something. We really aren’t able to help resolving such issues, but suggest uninstalling and reinstalling, and checking that the environment you’re running in is the same that you’re installing into.
