Memory refers to state in Chains. Memory can be used to store information about past executions of a Chain and inject that information into the inputs of future executions of the Chain. For example, for conversational Chains Memory can be used to store conversations and automatically add them to future model prompts so that the model has the necessary context to respond coherently to the latest input. Example: ```python class SimpleMemory(BaseMemory): memories: dict[str, Any] = dict() @property def memory_variables(self) -> list[str]: return list(self.memories.keys()) def load_memory_variables(self, inputs: dict[str, Any]) -> dict[str, str]: return self.memories def save_context( self, inputs: dict[str, Any], outputs: dict[str, str] ) -> None: pass def clear(self) -> None: pass ``` T)arbitrary_types_allowedcy)z;The string keys this memory class will add to chain inputs.Nselfs [/var/www/auto_recruiter/arenv/lib/python3.12/site-packages/langchain_classic/base_memory.pymemory_variableszBaseMemory.memory_variables?cy)zReturn key-value pairs given the text input to the chain.
