Development quickstart

Source Code

NIPY uses github for our code hosting. For immediate access to the source code, see the nipy github site.

Checking out the latest version

To check out the latest version of nipy you need git:

git clone git://

There are two methods to install a development version of nipy. For both methods, build the extensions in place:

python build_ext --inplace

Then you can either:

  1. Create a symbolic link in your site-packages directory to the inplace build of your source. The advantage of this method is it does not require any modifications of your PYTHONPATH.

  2. Place the source directory in your PYTHONPATH.

With either method, all of the modifications made to your source tree will be picked up when nipy is imported.

Getting data files

See data_files.


We have adopted many developer guidelines in an effort to make development easy, and the source code readable, consistent and robust. Many of our guidelines are adopted from the scipy / numpy community. We welcome new developers to the effort, if you’re interested in developing code or documentation please join the nipy mailing list and introduce yourself. If you plan to do any code development, we ask that you take a look at the following guidelines. We do our best to follow these guidelines ourselves:

Submitting a patch

The preferred method to submit a patch is to create a branch of nipy on your machine, modify the code and make a patch or patches. Then email the nipy mailing list and we will review your code and hopefully apply (merge) your patch. See the instructions for Making patches.

If you do not wish to use git and github, please feel free to file a bug report and submit a patch or email the nipy mailing list.

Bug reports

If you find a bug in nipy, please submit a bug report at the nipy bugs github site so that we can fix it.
