AttributeError with model.save related to TMCPPShim object

[rhyolight]

Original report: https://discourse.numenta.org/t/attributeerror-with-model-save-related-to-tmcppshim-object/2434

model = createModel()
model.enableInference({"predictedField": "cpu1"})
model.save(fullpath)

fullpath refers to the full string path to the directory where I wish to save the model.
createModel() is largely based on the OPF example code, though the parameters in my .yaml file are more like the ones seen in Matt's post here.

The exact error is:

AttributeError: ("'TMCPPShim' object has no attribute 'saveToFile'", u'occurred at index 0')

Environment: MAC
