返回类型:

bool

delete_all_agent() → bool

Delete all agents on the server.

download_file(path: str) → str

Download a file from a remote server to the local machine.

参数:

path (str) – The path of the file to be downloaded. Note that it is the path on the remote server.

str

get_agent_list() → Sequence[dict]

Get the summary of all agents on the server as a list.

返回:

list of agent summary information.

Sequence[str]

get_agent_memory(agent_id: str) → list[Msg] | Msg

Get the memory usage of the specific agent.

get_server_info() → dict

Get the agent server resource usage information.

is_alive() → bool

stop() → bool

Stop the agent server.

update_result(task_id: int, retry: ~agentscope.rpc.retry_strategy.RetryBase = <agentscope.rpc.retry_strategy.RetryFixedTimes object>) → str

Update the value of the async result.

备注

DON’T USE THIS FUNCTION IN ThreadPoolExecutor.

参数:

• retry (RetryBase) – Retry strategy. Defaults to RetryFixedTimes(10, 5).

返回:

Serialized value.

返回类型:

bytes

class RpcMeta(name: Any, bases: Any, attrs: Any)

基类：ABCMeta

The metaclass for all classes that can use to_dist and other distributed related functionality.

备注

The RpcMeta will automatically add the to_dist method and initialization parameter to its subclasses. And it will also detect all public functions and register them into the _info attribute of the class.

static get_class(cls_name: str) → Any

Get the class based on the specific class name.

参数:

cls_name (str) – the name of the class.

抛出:

ValueError – class name not exits.

返回:

the class

返回类型:

Any

static register_class(cls: type) → bool

Register the class into the registry.

参数:

cls (Type) – the class to be registered.

返回:

whether the registration is successful.

返回类型:

bool

static to_dist(self: ~typing.Any, 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.

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 _DEFAULT_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 RpcObject(cls: type, oid: str, host: str, port: int, connect_existing: bool = False, 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 | dict = <agentscope.rpc.retry_strategy.RetryFixedTimes object>, configs: dict | None = None)

基类：ABC

A proxy object which represent an object located in an Rpc server.

备注

When to_dist is called on an object or when using the to_dist parameter to create an object, the object is moved to an Rpc server, and an RpcObject instance is left behind in the local process. The RpcObject will automatically forward all public method invocations to the original object in the rpc server.

create(configs: dict) → None

create the object on the rpc server.

stop() → None

Stop the RpcAgent and the rpc server.

async_func(func: Callable) → Callable

A decorator for async function.

In distributed mode, async functions will return a AsyncResult immediately.

参数:

func (Callable) – The function to decorate.

sync_func(func: Callable) → Callable

A decorator for sync function.

In distributed mode, sync functions will block the current thread until the result is ready.

In most cases, you don’t need to use this decorator. RpcMeta will treat all public functions without async_func as sync_func. However, for magic methods (e.g. __str__ and __getitem__, which are started with __), you can use sync_func to mark them as sync.

参数:

func (Callable) – The function to decorate.
