[Smtk-developers] Help

[Yumin Yuan]

Hi Indu,

Are you using the latest smtk (https://github.com/Kitware/SMTK.git), or
some older build from CMB ? The module name should be called
"smtkCorePython" now with lower case "smtk". We changed the class name of
'smtk::attribute::Manager'  to 'smtk::attribute::System' a while back, so
older version of smtk will not have 'System' class.
