Error: 'Meta' object has no attribute 'model_dimension'

[jmlorenzi]

Hey Max,

This is regarding current state of the develop branch:

I suddenly started to get this error.

AttributeError: 'Meta' object has no attribute 'model_dimension'

This happened when I tried to export an .xml file that was generated earlier (with my backend-otf branch).

Do you have an idea what this could be related to? Did the 'model_dimension' property got moved from meta to somewhere else?

Some extra info:
As far I know, everything is consistent if you generate the .xml, export and run with the same code snapshot... I.e. regenerating the .xml from the render script solves the issue.

I had previously exported the .xml I mentioned first (with code from my backend-otf branch). I could run this model with the current state of the develop branch (but, as I said before, could not export it again).

I installed 'amos' in my Mac running El Capitan. When I execute the line kmos.cli.main('export myfirst_kmc.xml') inside my ipython (invoked as sudo ipython), then I get the same error as above :
AttributeError: 'Meta' object has no attribute 'model_dimension'

How do I run the model?

correction autotype, above 'amos' is 'kmos'

Hi,
In my experience this error occurs when there is some discrepancy among different Python versions. I have experienced it for example if I installed kmos using one version of Python and then tries to run a model using another version of Python.
It could also be the case that the xml file you are trying to export has been created using a different Python version than what you have installed.

Yes. I reinstalled macports and now this error has vanished.
