langchain.memory.buffer.ConversationStringBufferMemory

class langchain.memory.buffer.ConversationStringBufferMemory(*, human_prefix: str = 'Human', ai_prefix: str = 'AI', buffer: str = '', output_key: Optional[str] = None, input_key: Optional[str] = None, memory_key: str = 'history')

Bases: BaseMemory

Buffer for storing conversation memory.

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

param ai_prefix: str = 'AI'

Prefix to use for AI generated responses.

param buffer: str = ''

param human_prefix: str = 'Human'

param input_key: Optional[str] = None

param output_key: Optional[str] = None

clear() → None

Clear memory contents.

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

Return history buffer.

save_context(inputs: Dict[str, Any], outputs: Dict[str, str]) → None

Save context from this conversation to buffer.

to_json() → Union[SerializedConstructor, SerializedNotImplemented]

to_json_not_implemented() → SerializedNotImplemented

validator validate_chains  »  all fields

Validate that return messages is not True.

property lc_attributes: Dict

Return a list of attribute names that should be included in the serialized kwargs. These attributes must be accepted by the constructor.

property lc_namespace: List[str]

Return the namespace of the langchain object. eg. [“langchain”, “llms”, “openai”]

property lc_secrets: Dict[str, str]

Return a map of constructor argument names to secret ids. eg. {“openai_api_key”: “OPENAI_API_KEY”}

property lc_serializable: bool

Return whether or not the class is serializable.

property memory_variables: List[str]

Will always return list of memory variables. :meta private:
