wandb

Utility to flatten a nest run object into a list of runs. :param run: The base run to flatten. :return: The flattened list of runs.

Utility to truncate a list of runs dictionaries to only keep the specified keys in each run. :param runs: The list of runs to truncate. :param keep_keys: The keys to keep in each run. :return: The truncated list of runs.

Utility to modify the serialized field of a list of runs dictionaries. removes any keys that match the exact_keys and any keys that contain any of the partial_keys. recursively moves the dictionaries under the kwargs key to the top level. changes the "id" field to a string "_kind" field that tells WBTraceTree how to visualize the run. promotes the "serialized" field to the top level. :param runs: The list of runs to modify. :param exact_keys: A tuple of keys to remove from the serialized field. :param partial_keys: A tuple of partial keys to remove from the serialized field. :return: The modified list of runs.

Builds a nested dictionary from a list of runs. :param runs: The list of runs to build the tree from. :return: The nested dictionary representing the langchain Run in a tree structure compatible with WBTraceTree.

Arguments for the WandbTracer.

Callback Handler that logs to Weights and Biases.

This handler will log the model architecture and run traces to Weights and Biases. This will ensure that all LangChain activity is logged to W&B.
