'openmc' has no attribute 'SourceBase'

[BorKos]

Hey Jonathan, I've been playing around with your handy OpenMC tools, specifically the plotters. I've encountered this error with both the standalone source plotter and the OpenMC plot utility. Both were installed with pip. Should I be using a different version of OpenMC? I'm currently running version 0.13.3 (I dumped the version info at the end of the email. Thanks, Bor

ah sorry about that, it probably needs the current development branch of openmc

version 0.14.0 of openmc is looking like it will be released on conda in a few days.

perhaps we can wait for that release and then I can add some python code that checks the version is at least 0.14.0

many thanks for reporting
