 This Python module, named `portable_lib`, provides a set of functions and classes for loading and executing bundled programs. To install it, run the fullowing command:

 You can link the runtime against some backends to make sure a delegated or partitioned model can still run by Python module successfully:
 
 ```bash
-EXECUTORCH_BUILD_PYBIND=ON \
