param memories: Dict[str, Any] = {}

async aclear() → None

Async clear memory contents.

Return type:

None

async aload_memory_variables(inputs: dict[str, Any]) → dict[str, Any]

Parameters:

inputs (dict[str, Any]) – The inputs to the chain.

Returns:

A dictionary of key-value pairs.

Return type:

dict[str, Any]

async asave_context(inputs: dict[str, Any], outputs: dict[str, str]) → None

Async save the context of this chain run to memory.

Parameters:

• inputs (dict[str, Any]) – The inputs to the chain.

• outputs (dict[str, str]) – The outputs of the chain.

Return type:

None

clear() → None

Nothing to clear, got a memory like a vault.

Return type:

None

load_memory_variables(inputs: Dict[str, Any]) → Dict[str, str]

Return key-value pairs given the text input to the chain.

Parameters:

inputs (Dict[str, Any]) – The inputs to the chain.
