To learn more about prompt engineering and the callback please refer to this Report which explains both alongside the resultant dashboards you can expect to see.View Report Note: the WandbCallbackHandler is being deprecated in favour of the WandbTracer . In future please use the WandbTracer as it is more flexible and allows for more granular logging. To know more about the WandbTracer refer to the agent_with_wandb_tracing.html notebook or use the following colab notebook.
