MLflow Internal Prototype
=========================

Installing
----------
MLflow requires ``conda`` to be on the ``PATH`` for the projects feature.

We recommend installing MLflow in its own virtualenv for development, as follows::

    virtualenv env
    source env/bin/activate
    pip install -r dev-requirements.txt
    pip install -r tox-requirements.txt
    pip install -e .


Running a Sample App With the Tracking API
------------------------------------------
The programs in ``example`` use the MLflow Tracking API. For instance, run::

    python example/test.py

This program will use MLflow log API, which stores tracking data in ``./mlruns``, which can then be viewed with the Tracking UI.


Launching the Tracking UI
-------------------------

Development Mode
~~~~~~~~~~~~~~~~
If you installed MLflow for development (e.g. via ``pip install -e .``), ``npm`` is required to
build and run the UI. You can verify that ``npm`` is on the PATH by running ``npm -v``, and
`install npm <https://www.npmjs.com/get-npm>`_ if needed.

We recommend `Running the Javascript Dev Server`_ - otherwise, the tracking frontend will request
files in the ``mlflow/server/js/build`` directory, which is not checked into Git.
Alternatively, you can generate the necessary files in ``mlflow/server/js/build`` as described in
`Building a Distributable Artifact`_.

Starting the UI
~~~~~~~~~~~~~~~
The MLflow Tracking UI will show runs logged in ``./mlruns`` at `<http://localhost:5000>`_.
Start it with::

    mlflow ui


Running a Project from a URI
----------------------------
The ``mlflow run`` command lets you run a project packaged with a MLproject file from a local path
or a Git URI::

    mlflow run example/project -P num_dimensions=5

    mlflow run git@github.com:databricks/mlflow-example.git -P num_dimensions=5

See ``example/project`` for a sample project with an MLproject file.


Saving and Serving Models
-------------------------
To illustrate managing models, the ``mlflow.sklearn`` package can log Scikit-learn models as
MLflow artifacts and then load them again for serving. There is an example training application in
``example/test_sklearn.py`` that you can run as follows::

    $ python example/test_sklearn.py
    Score: 0.666
    Model saved in run RUN_ID

    $ mlflow sklearn serve -r RUN_ID model

    $ curl -d '[{"x": 1}, {"x": -1}]' -H 'Content-Type: application/json' -X POST localhost:5000/invocations


Tests and Lint
--------------
.. code::

    pytest
    ./lint.sh

Install Node Modules
--------------------
Before running the Javascript dev server or building a distributable wheel, install Javascript
dependencies via:

.. code::

   cd mlflow/server/js
   npm install
   cd - # go back to root repository directory

If modifying dependencies in mlflow/server/js/package.json, run `npm update` within mlflow/server/js
to install the updated dependencies.

Running the Javascript Dev Server
---------------------------------
`Install Node Modules`_, then run the following:

In one shell:

.. code::

   mlflow ui

In another shell:

.. code::

   cd mlflow/server/js
   npm start

The MLflow Tracking UI will show runs logged in ``./mlruns`` at `<http://localhost:3000>`_.

Building a Distributable Artifact
---------------------------------
`Install Node Modules`_, then run the following:

Generate JS files in ``mlflow/server/js/build``:

.. code::

   cd mlflow/server/js
   npm run build

Build a pip-installable wheel in ``dist/``:

.. code::

   cd -
   python setup.py bdist_wheel


Writing Docs
-------------
Make sure you have the requirements from ``dev-requirements.txt`` installed. Then run

.. code::

   cd docs
   make livehtml



Now Go With the Flow!
