Hi! I have the same error. I can successfully perform the classification with “gg-13-8-99-515-806-nb-classifier.qza”; however, if I run the same command with “silva-138-99-515-806-nb-classifier.qza” the following error is shown:
There was a problem with the command:
(1/1) Invalid value for ‘–i-classifier’: ‘silva-138-99-515-806-nb-classifier.qza’ is not a QIIME 2 Artifact (.qza)
This is the command I used:
qiime feature-classifier classify-sklearn
I have all files in the same folder and I also have enough free space (<300 Gb) in my hard disk. I donwloaded the SILVA database from the QIIME2 website.
Can you help me?
