Description

The Python module's type validation fails on my model. It is unclear why this fails, but when using _check_input_type and _check_return_type to bypass the type validation, I find that there are times where it is still attempting to validate. I tracked this down to model_utils.mustache. It appears that the _check_type flag is not being passed into 'attempt_convert_item'. I do not know if this is by design, but passing this parameter along solved my issue. I will submit a PR with the update.
