我正在尝试从 pysyft 运行联合学习（https://github.com/OpenMined/PySyft/blob/dev/examples/tutorials/advanced/websockets-example-MNIST-parallel/Asynchronous-federated-learning-on-MNIST .ipynb）创建远程工作人员并通过 websockets 连接到他们。但是我在执行评估步骤时遇到错误。
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'")>

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。
