Warnings from matplotlib in output
When using the Shellb3 from ftp://ftp/pub/shellb3/ShellB3-Linux-x86_64-CentOS6-20170801-rGIT8dfd19cb-py3-portable-core-cspp.tar.xz , AIT_FW_Quicklooks repeatedly generates this warning:
/home/adesmet/data/tmp/cspp-geo-aitf-1.0.3beta/lib/ShellB3/lib/python3.6/site-packages/matplotlib-2.0.2-py3.6-linux-x86_64.egg/matplotlib/ticker.py:1685: UserWarning: Steps argument should be a sequence of numbers
increasing from 1 to 10, inclusive. Behavior with
values outside this range is undefined, and will
raise a ValueError in future versions of mpl.
warnings.warn('Steps argument should be a sequence of numbers\n'
It seems like either there is a bug that should be fixed or a warning that should be suppressed.
