model_storage_output.py
-----------------------

This example shows defining a custom model that stores additional data.


.. code-block:: python

    import tempfile
    
    from modelrunner import make_model, open_storage
    
    
    def multiply(a, b=2, storage=None):
        storage["data"] = {"additional": "information"}
        return a * b
    
    
    with tempfile.NamedTemporaryFile(suffix=".yaml") as fp:
        # create an instance of the model defined by the function
        model = make_model(multiply, {"a": 3}, output=fp.name)
        # run the instance and store the data
        model.write_result()
    
        # read the file and check whether all the data is there
        with open_storage(fp.name) as storage:
            print("Stored data:", storage["storage/data"])
            print("Model result:", storage["result"])
