dspy.streaming.StatusMessageProvider

dspy.streaming.StatusMessageProvider

Provides customizable status message streaming for DSPy programs.

This class serves as a base for creating custom status message providers. Users can subclass and override its methods to define specific status messages for different stages of program execution, each method must return a string.

Example: 

class MyStatusMessageProvider(StatusMessageProvider):
    def lm_start_status_message(self, instance, inputs):
        return f"Calling LM with inputs {inputs}..."

    def module_end_status_message(self, outputs):
        return f"Module finished with output: {outputs}!"

program = dspy.streamify(dspy.Predict("q->a"), status_message_provider=MyStatusMessageProvider())
