Plug in error- qiime feature-classifier classify-sklearn

[zeineldn (Mohamed zeineldin)]

Hello,

Iam just running new data but this the first time to experinse this error during the taxonomic analysis.
Plugin error from feature-classifier:

The scikit-learn version (0.19.1) used to generate this artifact does not match the current version of scikit-learn installed (0.20.2). Please retrain your classifier for your current deployment to prevent data-corruption errors.

Debug info has been saved to /var/folders/cg/l_hcc6js1zz035s7m04kwyxdjyd_1j/T/qiime2-q2cli-err-c5zkfw_e.log

I dont know how to deal with it. I just use the code in the tutorial.
qiime feature-classifier classify-sklearn
–i-classifier gg-13-8-99-515-806-nb-classifier.qza
–i-reads rep-seqs.qza
–o-classification taxonomy.qza

Could you please advice?
Thank you

Hey there @zeineldn!

This error means that you have an old version of the greengenes pre-trained classifier on hand. The fix is to download again from the 2019.1 docs:

https://docs.qiime2.org/2019.1/data-resources/

Keep us posted!

Thank you Matthew,

You are right. but what is the case if I would like to work on ITS. I downloaded the UNITE database file in fasta format then convertwed it to .qza file using qiime import tool
qiime tools import --type ‘FeatureData[Sequence]’ -input-path UNITE_public_10.10.2017.fasta --output-path UNIT_2017_database.qza
I did that and got the same error.
What do you think?

Thank you again for your help !

Hi!
Not sure, but:

1. If you are using Qiime2 2019, you can use 2018 version and proceed with your classifier;
2. Or you can train classifier yourself and use 2019 version for it.
