Thank you for developing the Cyanoseq database, which is very helpful for aquatic microbial research. I want to use Cyanoseq database on my 16S rRNA gene amplicon sequencing data. I downloaded CyanoSeq_1.2_SILVA138.1_QIIME2_classifier.qza and found it is a trained database. So, I run these codes in Qiime2:
qiime feature-classifier classify-sklearn
--i-reads zotus.fa.qza
--i-classifier CyanoSeq_1.2_SILVA138.1_QIIME2_classifier.qza
--o-classification taxonomy.qza
But there is an error: Plugin error from feature-classifier: 0.
Here are messages in debug log file:

Qiime2 works well when using other reference database with the same data. So, I think there may be some problems with the file CyanoSeq_1.2_SILVA138.1_QIIME2_classifier.qza. Can you fix this?
Thank you very much for your reply and suggestions.
