PySIT has the following dependencies:

  • Python 3.7
  • NumPy 1.7 (or greater)
  • SciPy 0.12 (or greater)
  • matplotlib 1.3 (or greater)
  • PyAMG 2.05 (or greater)
  • ObsPy 0.85 (or greater)

For optional parallel support, PySIT can depend on:

  • MPI4Py 1.3.1 (or greater)

Installing Python and PySIT Dependencies

On all platforms (Linux, Windows 7 or greater, and MacOS X), we recommend a preassembled scientific python distribution, such as Continuum IO’s Anaconda or Enthought’s Canopy. These collections already include compatible (and in some cases accelerated) versions of most of PySIT’s dependencies. Download and follow the appropriate instructions for your operating system/distribution.

On Linux systems, you can also install Python and (many of) the dependencies from your package manager. For dependencies that are not available, you can download them and install them from source.

PySIT uses setuptools for packaging and is configured to automatically download and install the most up-to-date version of its dependencies from PyPI, if a satisfactory version is not already installed.

Installing PySIT

Install with pip

The most recent stable version PySIT is available on PyPI and can be installed by running:

pip install pysit --pre


The --pre option is absolutely necessary while the first release of pysit is still in a beta mode. As soon as this mode stabilizes, this will no longer be necessary.

To upgrade PySIT using pip:

pip install pysit --upgrade

Installing from source

PySIT uses C++ extensions, so you will need a functioning C++ compiler to install from source. For Windows users, if you are using one of the pre-built scientific Python distributions, one should be included, otherwise you will need to install an approprate version of MinGW. MacOS X users will need to install XCode.

From Git clone

This is the recommended way to install from source, as it will make it easiest to keep up with the latest bug fixes.


If you are planning on developing for PySIT, please see the Developer’s Guide.


This section assumes that you have git installed for your system.

  1. Clone PySIT from the master repository, hosted on github:

    git clone
  2. From the root of directory of your PySIT clone, run:

    python install
