Pysyft Federated learning, Error with Websockets

Question

我正在尝试从pysyft(https://github.com/OpenMined/PySyft/blob/dev/examples/tutorials/advanced/websockets-example-MNIST-parallel/Asynchronous-federated-learning-on-MNIST.ipynb(运行一个联合学习，该学习创建远程工作者并通过websockets连接到他们。 但是我在评估步骤中遇到错误。

future: <Task finished coro=<WebsocketServerWorker._producer_handler() done, defined at C:UsersPublicAnacondalibsite-packagessyftworkerswebsocket_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:

他们的论坛没有明确的答案。 有没有人知道这个脚本中的问题是什么。

我的syft版本：

syft : 0.2.3a1
syft-proto : 0.1.1a1.post12
torch : 1.4.0
