Unite dynamic classifier

Hi to all!
I have the latest release of QIIME2+Virtualbox (2019.4+6.0) and downloaded the UNITE classifiers from Link. When I try to use the dynamic classifier I got this message:

qiime feature-classifier classify-sklearn \

--i-classifier unite-ver8-dynamic-classifier.qza
--i-reads rep-seqs-merged.qza
--o-classification taxonomy-merged97-99.qza
Plugin error from feature-classifier:

Debug info has been saved to /tmp/qiime2-q2cli-err-lq2zdcox.log

qiime2-q2cli-err-lq2zdcox.txt (4.3 KB)

However, when I use the 99% classifier everything seem fine, even though I found myself trapped into this situation :wink: Link2.

Any idea? Thank in advance

Hi @Esteban_Ceriani,

Welcome to the forum! Looks like you ran into the ever common, MemoryError on VirtualBox when classifying reads. Have you had a chance to increase the memory of your virtual machine? Or are you already at the limit of your host computer?

You may have also just gotten unlucky with the memory usage at the time (perhaps too many tabs open on the host computer) which is why the dynamic classifier failed even though the 99% seemed to have enough room.

You were right! Changed from 4Gb to 9Gb ram...and worked perfectly.
