Plugin error from feature-classifier

Hello QIIME2 communit,

As I am new and still learning bioinformatic and QIIME2 , 2019.1 in particular, using Virtualbox, I ran into this problem:
qiime feature-classifier classify-sklearn \

–i-classifier gg-13-8-99-nb-classifier.qza
–i-reads rep-seqs.qza
–o-classification taxonomy.qza

Plugin error from feature-classifier:

Debug info has been saved to /tmp/qiime2-q2cli-err-l9b_6vro.log

and when I run this command
less /tmp/qiime2-q2cli-err-l9b_6vro.log
this happend:

other.ravel(), result.ravel())

I tried to Train feature classifiers with q2-feature-classifier
this one was successful but did not fix the issue

I hope you can help…

Hi @hitham_Almughram,
See the line at the bottom of the error:

This is a memory error, and is a common problem with this method. Use the search bar to read how to troubleshoot this problem:

hint: try a different classifier (e.g., greengenes) or use the reads-per-batch parameter.

Good luck!
