- PyInstaller hooks typically will need to import the package which they are written for but doing so may manipulate
- globals such as :data:`sys.path` or :data:`os.environ` in ways that affect the build. For example, on Windows,
- Qt's binaries are added to then loaded via ``PATH`` in such a way that if you import multiple Qt variants in one
- session then there is no guarantee which variant's binaries each variant will get!
- To get around this, PyInstaller does any such tasks in an isolated Python subprocess and ships a
- :mod:`PyInstaller.isolated` submodule to do so in hooks. ::
- from PyInstaller import isolated
- This submodule provides:
- * :func:`isolated.call() <call>` to evaluate functions in isolation.
- * :func:`@isolated.decorate <decorate>` to mark a function as always called in isolation.
- * :class:`isolated.Python() <Python>` to efficiently call many functions in a single child instance of Python.
