I was attempting to import single end sequences using a manifest file (Qiime version 2020.6). Here is the command:
qiime tools import \ --type 'SampleData[SequencesWithQuality]' \ --input-path level36_manifest \ --output-path L3L6-demux.qza \ --input-format SingleEndFastqManifestPhred33V2
This produced the following error:
/opt/nesi/CS400_centos7_bdw/QIIME2/2020.6/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: compiletime version 3.7 of module 'mtrand' does not match runtime version 3.6 return f(*args, **kwds) Segmentation fault
I then tried with version 2020.2, and it worked fine. Qiime2 was installed as a module on our national server (New Zealand). I have requested them to install latest version (2020.8), but would be good to know how this bug arose.
