An open source binding to, the public BigML API

Project description

BigML Python Bindings

`BigML <>`_ makes machine learning easy by taking care
of the details required to add data-driven decisions and predictive
power to your company. Unlike other machine learning services, BigML
`beautiful predictive models <>`_ that
can be easily understood and interacted with.

These BigML Python bindings allow you to interact with
` <>`_, the API
for BigML. You can use it to easily create, retrieve, list, update, and
delete BigML resources (i.e., sources, datasets, models and,
predictions). For additional information, see
the `full documentation for the Python
bindings on Read the Docs <>`_.

This module is licensed under the `Apache License, Version
2.0 <>`_.


Please report problems and bugs to our ` issue
tracker <>`_.

Discussions about the different bindings take place in the general
`BigML mailing list <>`_. Or join us
in our `Campfire chatroom <>`_.


Python 2.7 and Python 3 are currently supported by these bindings.

The basic third-party dependencies are the
`requests <>`_,
`poster <>`_,
`unidecode <>`_ and
`requests-toolbelt <>`_
libraries. These
libraries are automatically installed during the setup. Support for Google
App Engine has been added as of version 3.0.0, using the `urlfetch` package
instead of `requests`.

The bindings will also use ``simplejson`` if you happen to have it
installed, but that is optional: we fall back to Python's built-in JSON
libraries is ``simplejson`` is not found.

Additional `numpy <>`_ and
`scipy <>`_ libraries are needed in case you want to use
local predictions for regression models (including the error information)
using proportional missing strategy. As these are quite heavy libraries and
they are so seldom used, they are not included in the automatic installation
dependencies. The test suite includes some tests that will need these
libraries to be installed.

Also in order to use local `Topic Model` predictions, you will need to install
`pystemmer <>`_. Using the `pip install`
command for this library can produce an error if your system lacks the
correct developer tools to compile it. In Windows, the error message
will include a link pointing to the needed Visual Studio version and in
OSX you'll need to install the Xcode developer tools.


To install the latest stable release with
`pip <>`_

.. code-block:: bash

$ pip install bigml

You can also install the development version of the bindings directly
from the Git repository

.. code-block:: bash

$ pip install -e git://

Running the Tests

The test will be run using `nose <>`_ ,
that is installed on setup, and you'll need to set up your authentication
via environment variables, as explained
below. With that in place, you can run the test suite simply by issuing

.. code-block:: bash

$ python nosetests

Some tests need the `numpy <>`_ and
`scipy <>`_ libraries to be installed too. They are not
automatically installed as a dependency, as they are quite heavy and very
seldom used.

Importing the module

To import the module:

.. code-block:: python

import bigml.api

Alternatively you can just import the BigML class:

.. code-block:: python

from bigml.api import BigML


All the requests to must be authenticated using your username
and `API key <>`_ and are always
transmitted over HTTPS.

This module will look for your username and API key in the environment
variables ``BIGML_USERNAME`` and ``BIGML_API_KEY`` respectively. You can
add the following lines to your ``.bashrc`` or ``.bash_profile`` to set
those variables automatically when you log in:

.. code-block:: bash

export BIGML_USERNAME=myusername
export BIGML_API_KEY=ae579e7e53fb9abd646a6ff8aa99d4afe83ac291

With that environment set up, connecting to BigML is a breeze:

.. code-block:: python

from bigml.api import BigML
api = BigML()

Otherwise, you can initialize directly when instantiating the BigML
class as follows:

.. code-block:: python

api = BigML('myusername', 'ae579e7e53fb9abd646a6ff8aa99d4afe83ac291')

**Note** that the previously existing ``dev_mode`` flag:

.. code-block:: python

api = BigML(dev_mode=True)

that caused the connection to work with the Sandbox ``Development Environment``
has been **deprecated** because this environment does not longer exist.
The existing resources that were previously
created in this environment have been moved
to a special project in the now unique ``Production Environment``, so this
flag is no longer needed to work with them.

Quick Start

Imagine that you want to use `this csv
file <>`_ containing the `Iris
flower dataset <>`_ to
predict the species of a flower whose ``petal length`` is ``2.45`` and
whose ``petal width`` is ``1.75``. A preview of the dataset is shown
below. It has 4 numeric fields: ``sepal length``, ``sepal width``,
``petal length``, ``petal width`` and a categorical field: ``species``.
By default, BigML considers the last field in the dataset as the
objective field (i.e., the field that you want to generate predictions


sepal length,sepal width,petal length,petal width,species

You can easily generate a prediction following these steps:

.. code-block:: python

from bigml.api import BigML

api = BigML()

source = api.create_source('./data/iris.csv')
dataset = api.create_dataset(source)
model = api.create_model(dataset)
prediction = api.create_prediction(model, \
{'petal length': 2.45, 'petal width': 1.75})

You can then print the prediction using the ``pprint`` method:

.. code-block:: python

>>> api.pprint(prediction)
species for {"petal width": 1.75, "petal length": 2.45} is Iris-setosa

The ``iris`` dataset has a small number of instances, and usually will be
instantly created, so the ``api.create_`` calls will probably return the
finished resources outright. As BigML's API is asynchronous,
in general you will need to ensure
that objects are finished before using them by using ``api.ok``.

.. code-block:: python

from bigml.api import BigML

api = BigML()

source = api.create_source('./data/iris.csv')
dataset = api.create_dataset(source)
model = api.create_model(dataset)
prediction = api.create_prediction(model, \
{'petal length': 2.45, 'petal width': 1.75})

This method retrieves the remote object in its latest state and updates
the variable used as argument with this information. Note that the prediction
call is not followed by the ``api.ok`` method. Predictions are so quick to be
generated that, unlike the
rest of resouces, will be generated synchronously as a finished object.

You can also generate an evaluation for the model by using:

.. code-block:: python

test_source = api.create_source('./data/test_iris.csv')
test_dataset = api.create_dataset(test_source)
evaluation = api.create_evaluation(model, test_dataset)

If you set the ``storage`` argument in the ``api`` instantiation:

.. code-block:: python

api = BigML(storage='./storage')

all the generated, updated or retrieved resources will be automatically
saved to the chosen directory.
You can also check other simple examples in the following documents:

- `model 101 <docs/101_model.html>`_
- `logistic regression 101 <docs/101_logistic_regression.html>`_
- `ensemble 101 <docs/101_ensemble.html>`_
- `cluster 101 <docs/101_cluster>`_
- `anomaly detector 101 <docs/101_anomaly.html>`_
- `association 101 <docs/101_association.html>`_
- `topic model 101 <docs/101_topic_model.html>`_
- `time series 101 <docs/101_ts.html>`_

Additional Information

We've just barely scratched the surface. For additional information, see
the `full documentation for the Python
bindings on Read the Docs <>`_.
Alternatively, the same documentation can be built from a local checkout
of the source by installing `Sphinx <>`_
(``$ pip install sphinx``) and then running

.. code-block:: bash

$ cd docs
$ make html

Then launch ``docs/_build/html/index.html`` in your browser.
