Good morning,
I’m trying to make the taxonomy of my samples, but I have this problem … can you help me?
thanks

Plugin error from feature-classifier:

The scikit-learn version (0.20.2) used to generate this artifact does not match the current version of scikit-learn installed (0.21.2). Please retrain your classifier for your current deployment to prevent data-corruption errors.

The new version of qiime is using a different version of scikit-learn so you’ll have to retrain your classifiers. Alternatively you can look for pre-trained classifiers such as these I made for silva database, or the official ones, which also includes green genes.
