pipnest

pipnest packages your NEST extension modules into pip installable packages. This is a benefit when you're distributing a Python model for the NEST simulator and have a dependency on an extension module. Instead of having to provide installation instructions to your end-users you can have pip download and build the extension module into the target machine's nest installation.

Usage

Project structure

• Prepare a folder with 1 subfolder that contains a NEST extension modules.
• The source code of the extension module can not be in the root repository.
• The name of your module should be the name of your folders plus "module".

Your project structure should look like this:

- my_module
  - my_module
    - my_file1.cpp
    - my_file2.cpp
    - ...

In this example your NEST module should be called the my_modulemodule.

Initialize project

Run the pipnest init command from the root folder and fill in the requested metadata:

cd my_module
pipnest init .

This should create a setup.py and README.md, be sure to edit the latter. Check that your module is present under the packages keyword argument in setup.py.

Package

Create the source distribution:

python setup.py sdist

Test your package locally

• Remove any already installed versions from the $NEST_INSTALL_DIR/lib/nest folder
• Run pip install dist/*. (If an MPI error occurs, restart your terminal and try again)

Upload to PyPI

Use twine to upload your package:

twine upload dist/* --skip-existing
