Thanks Yumin. Can you suggest me the path of System attribute so that I can manually check it?  It seems I do have right version.

Hi Indu,

Yes I am using the same build. Do you suggest to use import smtkCorePython instead of just smtk?

No, what I meant is, in the latest smtk build, there should be no "SMTKCorePython" lib anymore, instead you should have a "smtkCorePython" lib. The fact that you error message says "AttributeError: type object 'SMTKCorePython.smtk.attribute' has no attribute 'System'" suggests that this is an older version of smtk, because the latest smtk should have said "AttributeError: type object 'smtkCorePython.smtk.attribute' has no .....".

I tried that, but it is giving me build errors. I have installed shiboken as well but in the link it says to ignore shiboken warnings.

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.

David,

I simplified the script even further. But still get this error.

Error:
Traceback (most recent call last):
  File "<string>", line 5, in <module>
  File "/Users/indushukla/Documents/workspace/ADH_Test_Today/source/Root/Test/MetXL.py", line 8, in <module>
    asys = smtk.attribute.System()
AttributeError: type object 'SMTKCorePython.smtk.attribute' has no attribute 'System'

Thanks!

Indu

Hi Inda,

It looks like you call "import smtk" twice. This is not an error, however, the variables asys and mmgr are populated at lines 25 and 26 only if the second import attempt fails. Since it is not failing, there are probably statements below that try to call methods on undefined variables.
