No space left on device

Hi Qiime team

I got one error that showed Errno 28 when I was creating a classifier. The command I used is “qiime feature-classifier fit-classifier-naive-bayes --i-reference-reads ref-seqs_805.qza --i-reference-taxonomy ref-taxonomy.qza --o-classifier classifier_805.qza --verbose”

The error infor is

/opt/miniconda3/envs/qiime2-2017.12/lib/python3.5/site-packages/q2_feature_classifier/ UserWarning: The TaxonomicClassifier artifact that results from this method was trained using scikit-learn version 0.19.1. It cannot be used with other versions of scikit-learn. (While the classifier may complete successfully, the results will be unreliable.)

OSError: [Errno 28] No space left on device

Plugin error from feature-classifier:

[Errno 28] No space left on device

See above for debug info.

I have referred to several previous threads, but still did not solve the problem. Hope you can help!


Some supplementary information: I am using a server based on a University and the version of qiime is 2017.12. We have checked there should be plenty of space on the server.

I imagine you ran out of temp dir space - check out the topics in this search for some recommendations:
