Installing with pip

Installing Zipline via pip is slightly more involved than the average Python package.

There are two reasons for the additional complexity:

  1. 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.
  2. Zipline depends on numpy, the core library for numerical array computing in Python. Numpy depends on having the 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 as your Python distribution, you can skip to the Installing with Conda section.

Once you’ve installed the necessary additional dependencies (see below for your particular platform), you should be able to simply run

$ pip install zipline

If you use Python for anything other than Zipline, we strongly recommend that you install in a virtualenv. The Hitchhiker’s Guide to Python provides an excellent tutorial on virtualenv.


On Debian-derived Linux distributions, you can acquire all the necessary binary dependencies from apt by running:

$ sudo apt-get install libatlas-base-dev python-dev gfortran pkg-config libfreetype6-dev

On recent RHEL-derived derived Linux distributions (e.g. Fedora), the following should be sufficient to acquire the necessary additional dependencies:

$ sudo dnf install atlas-devel gcc-c++ gcc-gfortran libgfortran python-devel redhat-rep-config

On Arch Linux, you can acquire the additional dependencies via pacman:

$ pacman -S lapack gcc gcc-fortran pkg-config

There are also AUR packages available for installing ta-lib, an optional Zipline dependency. Python 2 is also installable via:

$ pacman -S python2


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, 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:

$ brew install freetype pkg-config gcc openssl


For windows, the easiest and best supported way to install zipline is to use Conda.

Installing with conda

Another way to install Zipline is via the conda package manager, which comes as part of Continuum Analytics’ Anaconda 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

Once conda has been set up you can install Zipline from our Quantopian channel:

conda install -c Quantopian zipline

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

Assuming conda has been set up, you can create a conda environment:

  • Python 2.7:
$ conda create -n env_zipline python=2.7
  • Python 3.5:
$ conda create -n env_zipline python=3.5

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

$ source activate env_zipline

You can install Zipline by running

(env_zipline) $ conda install -c Quantopian zipline

To deactivate the conda environment:

(env_zipline) $ source deactivate
