Model Definition Injection
Both the python and R runners support an optional parameter for the init function. Normally, the init function is defined with 0 arguments, but if a single argument is defined, the runner will populate that argument with a ‘model definition’ object. In python, this object is a dictionary. In R, this object is a list. In both cases, the object has two keys. There will be a ‘rawJson’ key that contains the unparsed json string that contains either the job or the deployedModel object in its serialized form. There will also be either a ‘job’ or a ‘deployedModel' key, the value of which will either be a deserialized job or deployedModel object. In python, the deserialized job or deployedModel will be the result of calling json.loads() on the contents of the ‘rawJson’ field. In R, it will be the result of calling the jsonlite fromJSON function.

print(model_def$deployedModel)
