Python Pysyft联合学习，WebSocket错误

我正在尝试运行一个从pysyft（）开始的联合学习，它创建远程工作者并通过websockets连接到他们。然而，我在执行评估步骤时遇到了一个错误

future: <Task finished coro=<WebsocketServerWorker._producer_handler() done, defined at C:\Users\Public\Anaconda\lib\site-packages\syft\workers\websocket_server.py:95> exception=AttributeError("'dict' object has no attribute 'owner'")>

    register_response_function = register_response_functions[attr_id]
KeyError: 'evaluate'

During handling of the above exception, another exception occurred:
