ZnTrack
-------
The ZnTrack :code:`zɪŋk træk` package provides a Python ORM for DVC.

For more information on DVC visit their `homepage <https://dvc.org/doc>`_.

Example
========
ZnTrack allows you to convert most Python classes into a DVC stage, including
parameters, dependencies and all DVC output types.

.. code-block:: py

    from zntrack import Node, DVC
    from random import randrange


    @Node()
    class HelloWorld:
        """Define a ZnTrack Node"""
        # parameter to be tracked
        max_number = DVC.params()   
        # parameter to store as output
        random_number = DVC.result()  

        def __call__(self, max_number):
            """Pass tracked arguments"""
            self.max_number = max_number

        def run(self):
            """Command to be run by DVC"""
            self.random_number = randrange(self.max_number)

This stage can be used via

.. code-block:: py

    hello_world = HelloWorld()
    hello_world(max_number=512)

which builds the DVC stage and can be used e.g., through :code:`dvc repro`.
The results can then be accessed easily via :code:`HelloWorld(load=True).random_number`.
