Module contents

Import all environment related modules in the package.

class agentscope.environment.Event(name: str, args: dict | None = None, returns: Any | None = None)

基类：object

A class representing the information of an event.

It contains the name of the event, the arguments of the event, and the returns of the event.

__init__(name: str, args: dict | None = None, returns: Any | None = None) → None

property name: str

Return the name of the event.

property args: dict

Return the arguments of the event.

property returns: Any

Return the returns of the event.

agentscope.environment.event_func(func: Callable) → Callable

A decorator to register an event function in Env and its subclasses.

备注

This decorator is only available in the subclasses of Env. If a function is decorated with @event_func, at the end of the function, all listeners bound to the function will be triggered automatically.

参数:

func (Callable) – The event function.

返回:

The decorated event function.

返回类型:

Callable

class agentscope.environment.Env(*args: tuple, **kwargs: dict)

基类：ABC

The Env Interface. Env is a key concept of AgentScope, representing global data shared among agents.

Each env has its own name and value, and multiple envs can be organized into a tree structure, where each env can have multiple children envs.

Different implementations of envs may have different event functions, which are marked by @event_func. Users can bind EventListener to specific event functions, and the listener will be activated when the event function is called.

abstract add_listener(target_event: str, listener: EventListener) → bool

Convert current object into its distributed version.

参数:

• host (str, defaults to “localhost”) – Hostname of the rpc agent server.

• port (int, defaults to None) – Port of the rpc agent server.

• max_pool_size (int, defaults to 8192) – Only takes effect when host and port are not filled in. The max number of agent reply messages that the started agent server can accommodate. Note that the oldest message will be deleted after exceeding the pool size.

• max_expire_time (int, defaults to 7200) – Only takes effect when host and port are not filled in. Maximum time for reply messages to be cached in the launched agent server. Note that expired messages will be deleted.

• max_timeout_seconds (int, defaults to 5) – Max timeout seconds for the rpc call.

• local_mode (bool, defaults to True) – Only takes effect when host and port are not filled in. Whether the started agent server only listens to local requests.

• retry_strategy (RetryBase, defaults to _DEAFULT_RETRY_STRATEGY) – The retry strategy for the async rpc call.

返回:

the wrapped agent instance with distributed functionality

返回类型:

RpcObject

class agentscope.environment.BasicEnv(*args: tuple, **kwargs: dict)
