langchain.callbacks.aim_callback.AimCallbackHandler

class langchain.callbacks.aim_callback.AimCallbackHandler(repo: Optional[str] = None, experiment_name: Optional[str] = None, system_tracking_interval: Optional[int] = 10, log_system_params: bool = True)

Bases: BaseMetadataCallbackHandler, BaseCallbackHandler

Callback Handler that logs to Aim.

Parameters

• repo (str, optional) – Aim repository path or Repo object to which Run object is bound. If skipped, default Repo is used.

• experiment_name (str, optional) – Sets Run’s experiment property. ‘default’ if not specified. Can be used later to query runs/sequences.

• system_tracking_interval (int, optional) –

  Sets the tracking interval in seconds for system usage metrics (CPU, Memory, etc.). Set to None

  to disable system metrics tracking.

• log_system_params (bool, optional) – Enable/Disable logging of system params such as installed packages, git info, environment variables, etc.

This handler will utilize the associated callback method called and formats the input of each callback function with metadata regarding the state of LLM run and then logs the response to Aim.

Initialize callback handler.
