Support multiple callbacks per step type in step_callbacks dict by albertvillanova · Pull Request #1517 · huggingface/smolagents (original) (raw)

Support multiple callbacks per step type in step_callbacks dict.

This PR enhances the step_callbacks parameter in MultiStepAgent to support registering multiple callbacks for the same step type when using the dictionary format.

Note:

• Previously, the dictionary format only supported mapping each step type to a single callback function.
• Now users can specify multiple callbacks for the same step type by passing a list.
• Maintains full backward compatibility with existing code.
