When I was running
qiime feature-classifier fit-classifier-naive-bays --i-reference-reads ref-seqs.qza --i-reference-taxonomy ref-taxonomy.qza --o-classifier gg_study1_classifier.qza
The following error came:
Plugin error from feature-classifier:

Hi @wym199633,
3GB is usually not enough memory for training a classifier with most reference sequence databases. You should increase the amount of memory available (and move to a separate machine if necessary). You can check out other threads on this forum, e.g., the link I supplied above, for other advice on addressing this problem.
You can also try one of the other classifiers, e.g., classify-consensus-blast, which are less memory-intensive.
