Python model persistence without pickling Are there any Python machine learning libraries, which allow model persistence without pickling?

More specifically, I want to avoid problems (and time sinks) that could arise upon sharing models with others. (In my case: academic collaborators in non-computational research fields.)
One option is to export the model to Predictive Model Markup Language (PMML) format.

In scikit-learn, sklearn2pmml can be used.
