pipInstalling Zipline via pip is slightly more involved than the average
Python package.
There are two reasons for the additional complexity:
Zipline ships several C extensions that require access to the CPython C API.
In order to build the C extensions, pip needs access to the CPython
header files for your Python installation.
Zipline depends on numpy <https://www.numpy.org/>, the core library for
numerical array computing in Python. Numpy depends on having the LAPACK <https://www.netlib.org/lapack> linear algebra routines available.
Because LAPACK and the CPython headers are non-Python dependencies, the correct
way to install them varies from platform to platform. If you'd rather use a
single tool to install Python and non-Python dependencies, or if you're already
using Anaconda <https://www.anaconda.com/distribution/>_ as your Python distribution,
you can skip to the :ref:Installing with Conda <conda> section.
Once you've installed the necessary additional dependencies (see below for your particular platform), you should be able to simply run
.. code-block:: bash
$ pip install zipline
If you use Python for anything other than Zipline, we strongly recommend
that you install in a virtualenv <https://virtualenv.readthedocs.org/en/latest>. The Hitchhiker's Guide to Python provides an excellent tutorial on virtualenv <https://docs.python-guide.org/en/latest/dev/virtualenvs/>_.
GNU/Linux
On `Debian-derived`_ Linux distributions, you can acquire all the necessary
binary dependencies from ``apt`` by running:
.. code-block:: bash
$ sudo apt-get install libatlas-base-dev python-dev gfortran pkg-config libfreetype6-dev hdf5-tools
On recent `RHEL-derived`_ derived Linux distributions (e.g. Fedora), the
following should be sufficient to acquire the necessary additional
dependencies:
.. code-block:: bash
$ sudo dnf install atlas-devel gcc-c++ gcc-gfortran libgfortran python-devel redhat-rpm-config hdf5
On `Arch Linux`_, you can acquire the additional dependencies via ``pacman``:
.. code-block:: bash
$ pacman -S lapack gcc gcc-fortran pkg-config hdf5
There are also AUR packages available for installing `ta-lib
<https://aur.archlinux.org/packages/ta-lib/>`_, an optional Zipline dependency.
Python 2 is also installable via:
.. code-block:: bash
$ pacman -S python2
OSX
~~~
The version of Python shipped with OSX by default is generally out of date, and
has a number of quirks because it's used directly by the operating system. For
these reasons, many developers choose to install and use a separate Python
installation. The `Hitchhiker's Guide to Python`_ provides an excellent guide
to `Installing Python on OSX <https://docs.python-guide.org/en/latest/>`_, which
explains how to install Python with the `Homebrew`_ manager.
Assuming you've installed Python with Homebrew, you'll also likely need the
following brew packages:
.. code-block:: bash
$ brew install freetype pkg-config gcc openssl hdf5
Windows
~~~~~~~
For windows, the easiest and best supported way to install zipline is to use
:ref:`Conda <conda>`.
.. _conda:
Installing with ``conda``
-------------------------
Another way to install Zipline is via the ``conda`` package manager, which
comes as part of Continuum Analytics' `Anaconda
<https://www.anaconda.com/distribution/>`_ distribution.
The primary advantage of using Conda over ``pip`` is that conda natively
understands the complex binary dependencies of packages like ``numpy`` and
``scipy``. This means that ``conda`` can install Zipline and its dependencies
without requiring the use of a second tool to acquire Zipline's non-Python
dependencies.
For instructions on how to install ``conda``, see the `Conda Installation
Documentation <https://conda.io/projects/conda/en/latest/user-guide/install/index.html>`_
Once ``conda`` has been set up you can install Zipline from the ``conda-forge`` channel:
.. code-block:: bash
conda install -c conda-forge zipline
.. _`Debian-derived`: https://www.debian.org/derivatives/
.. _`RHEL-derived`: https://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux_derivatives
.. _`Arch Linux` : https://www.archlinux.org/
.. _`Hitchhiker's Guide to Python` : https://docs.python-guide.org/en/latest/
.. _`Homebrew` : https://brew.sh
.. _managing-conda-environments:
Managing ``conda`` environments
It is recommended to install Zipline in an isolated conda environment.
Installing Zipline in conda environments will not interfere your default
Python deployment or site-packages, which will prevent any possible conflict
with your global libraries. For more information on conda environment, see
the Conda User Guide <https://conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html>_.
Assuming conda has been set up, you can create a conda environment:
.. code-block:: bash
$ conda create -n env_zipline python=3.6
Now you have set up an isolated environment called env_zipline, a sandbox-like
structure to install Zipline. Then you should activate the conda environment
by using the command
.. code-block:: bash
$ conda activate env_zipline
You can install Zipline by running
.. code-block:: bash
(env_zipline) $ conda install -c conda-forge zipline
.. note::
The ``conda-forge`` channel so far only has zipline 1.4.0+ packages for python 3.6.
Conda packages for previous versions of zipline for pythons 2.7/3.5/3.6 are
still available on Quantopian's anaconda channel, but are not being updated.
They can be installed with:
.. code-block:: bash
(env_zipline35) $ conda install -c Quantopian zipline
To deactivate the conda environment:
.. code-block:: bash
(env_zipline) $ conda deactivate
.. note::
conda activate and conda deactivate only work on conda 4.6 and later versions. For conda versions prior to 4.6, run:
* Windows: ``activate`` or ``deactivate``
* Linux and macOS: ``source activate`` or ``source deactivate``
