PySIT Extension Development Guide


Any methods or algorithms from the literature that are not patent or license restricted can be included directly within the PySIT Core package. If any part of your extension fits these criteria (must be BSD licensed) and you think that it will be useful to the rest of the community, we strongly encourage you to do so. For example, if you add support for a new acquisition geometry or a new gallery problem, submit these as a pull request to the core package, rather than releasing them through your extension.

To move existing research code into a PySIT extension:

  1. Clone or fork the example PySIT Extension package from BitBucket.
  2. Rename the example to the name of your extension.
  3. Update the configuration in
  4. Update the licenses/license.rst file.
  5. Copy your new script files to the pysit_extensions-<extname>/pysit_extensions directory. It is requested that you follow the PySIT package structure wherever possible: e.g., new solvers go in the solvers directory and new objective functions go in the objective_functions directory.
  6. Copy any demo or example scripts into the examples directory.
  7. Setup the configuration to build any C, C++, fortran, or Cython extensions.
  8. If releasing publically, configure and upload to PyPI.
