Hi @lwcoding!  
I was able to find a few other instances of this error by [searching the forum](https://forum.qiime2.org/search?q=scikit%20learn%20version). Give those suggestions a try. Please let me know if you are continuing to get no output on the other blocks, but I am hopeful that fixing this error will resolve the rest.

> Plugin error from feature-classifier: The scikit-learn version (0.23.1) used to generate this artifact does not match the current version of scikit-learn installed (0.24.2). Please retrain your classifier for your current deployment to prevent data-corruption errors. Debug info has been saved to /tmp/qiime2-q2cli-err-953fotk6.log my qiime2 is2021.4 What can I do to make it work ?
