Error feature classifier fit classifier naive bayes

qiime feature-classifier fit-classifier-naive-bayes --i-reference-reads silva132-ref-seqs.qza --i-reference-taxonomy silva132-ref-taxonomy.qza --o-classifier silva132-classifier.qza

After increasing the memory of the VM (35GB) I ran the command like above and got the following error. What is happening? Any comments and solutions are very welcomed!!!
