error in feature-classifier

[Jing]

Dear all:

I am running the following command on qiime2-2020.2(VM RAM 4096MB)

time qiime feature-classifier classify-sklearn
–i-classifier silva-132-99-515-806-nb-classifier.qza
–i-reads rep-seqs.qza
–o-classification taxonomy.qza

The process stops midway and I get the following message, suggesting a memory error.

I don’t know if there is too little RAM for the VM to run feature-classifier.

Thankss!

You need to allocate more memory in VM settings or use a stronger machine

I’m going to recommend you check out this topic about memory errors, because it’s a frequency problem!
