Save the module.

Save the module to a directory or a file.

We also save the dependency versions, so that the loaded model can check if there is a version mismatch on critical dependencies or DSPy version.

Parameters:

Name Type Description Default
path str

Path to the saved state file, which should be a .json or .pkl file when save_program=False, and a directory when save_program=True.

 required
save_program bool

If True, save the whole module to a directory via cloudpickle, otherwise only save the state.
