DVC
===

DVC is a Version Control System for Machine Learning Projects.

Previously we have added a dataset to dvc.
Now we make use of the second feature of DVC - *Reproducibility*.

You can create stages to execute a command and track their dependencies and outputs.

A stage is simply created by this command:

.. prompt:: bash

  dvc run \
      -n NAME_OF_THE_STAGE \
      -d DEPENDENCY_1 \
      -d DEPENDENCY_2 \
      -o OUTPUT_1 \
      -o OUTPUT_2 \
      COMMAND

DVC will automatically create a :file:`dvc.yaml` and :file:`dvc.lock` file,
to track your dependencies and outputs.

A :file:`dvc.yaml` file could look like this:

.. code:: yaml

  stages:
      NAME_OF_THE_STAGE:
      cmd: COMMAND
      deps:
      - DEPENDENCY_1
      - DEPENDENCY_2
      outs:
      - OUTPUT_1
      - OUTPUT_2

.. admonition:: Your Task

  Create dvc stages for training and testing.
