What is Subzero?

The goal of subzero is to allow simple and rapid deployment of frozen Python applications with minimal additional effort and developer time. In contrast to other solutions, subzero’s philosophy is that having a working application, quickly is more important than optimizing for size or other factors and that generating your end product (be it an MSI, or other installer) should take only a few minutes to set up. Subzero builds on the extensive development work of other projects, and doesn’t re-invent the wheel. Rather, it ties everything together in a simple and intuitive manner.

How do I use it?

In your setup file, replace the default setup import with the followng:

from subzero import setup, Executable

Then run the following command:

python bdist_msi

Subzero will the build executables specified in the entry_points and scripts sections and then create an installer that contains those executables.


        'gui_scripts': [
                    'gui = app.__main__:gui',
        'console_scripts': [
            'console = app.__main__:console',
        'build_exe': {
            [os.path.join(os.path.dirname(PyQt5.__file__), 'Qt', 'bin')],
            [datafile, '.')],
        'bdist_msi': {
            'upgrade_code': '84b31ed7-3985-46ad-9d07-eb4140a6d44a',
            'shortcuts': ['My Program = gui'],

Options are applied first globally from the options dictionary passed to setup, and then for each executable if the Executable class is present for that particular entry_point or script.

The full array of options for build_exe is available in the PyInstaller documentation. Providing an upgrade code is strongly recommended for the bdist_msi command. A license agreement will be added to the installer if there is a license text file in the same directory as

Extended import discovery (In beta)

In case PyInstaller cannot discover all of your dependencies, you can set optimize_imports=False, as shown below. This option may discover certain imports previously not found but it may also make your application larger. Note that you must add your package requirements in install_requires for this option to work!

'build_exe': {
    'optimize_imports': False


Cython modules can also be built because Subzero executes the builtin build command before calling PyInstaller. Just add your modules to the ext_modules key:

from setuptools import find_packages, Extension
from subzero import setup
