agentscope.environment.env module

The env module.

agentscope.environment.env.trigger_listener(env: Env, event: Event) → None[source]

Trigger the listener bound to the event.

Parameters:

  • env (Env) – The env that trigger the listener.

  • event (Event) – The event information.

agentscope.environment.env.event_func(func: Callable) → Callable[source]

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

Note

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.

Parameters:

func (Callable) – The event function.

Returns:

The decorated event function.

Return type:

Callable

class agentscope.environment.env.EventListener(name: str)[source]

Bases: ABC

A base class representing a listener for listening the event of an environment. The actions of the listener should be implemented in the __call__ method.

Parameters:

  • env (Env) – The environment instance who trigger the listener.

  • event (Event) – The event information, which contains the event

  • (name (function name) – str), the arguments of the event function

  • (args – dict), and the return value of the event function

  • (returns – Any).

Note

EventListener can only be bound to event functions (decorated with @event_func).

__init__(name: str) → None[source]

Init a EventListener instance.

Parameters:

name (str) – The name of the listener.

class agentscope.environment.env.Env(*args: tuple, **kwargs: dict)[source]

Bases: 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.

Returns:

The name of the env.

str

abstract describe(**kwargs: Any) → str[source]

Describe the current state of the environment.

to_dist(host: str = 'localhost', port: int | None = None, max_pool_size: int = 8192, max_expire_time: int = 7200, max_timeout_seconds: int = 5, local_mode: bool = True, retry_strategy: ~agentscope.rpc.retry_strategy.RetryBase = <agentscope.rpc.retry_strategy.RetryFixedTimes object>) → Any

Convert current object into its distributed version.

Parameters:

  • 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.

the wrapped agent instance with distributed functionality

Return type:

RpcObject

class agentscope.environment.env.BasicEnv(*args: tuple, **kwargs: dict)[source]
