Level of Support

We are releasing this code to the public as a tool we expect others to use. Questions concerning bugs and related issues are welcomed. We expect to address them promptly, pull requests will vetted by our staff before inclusion.


bmtk requires Python 2.7 or 3.5+, plus additional python dependicies. To install with base requirements from a command-line:

 $ git clone
 $ cd bmtk
 $ python install

There are examples of building models and running simulations located in docs/examples/. Some of the simulation engines may require additonal requirements to run.


There are a collection of unit-tests in bmtk.tests which can be run using pytest

  $ cd bmtk
  $ py.test
