Hi @fairyto2, 可否贴一下完整的代码？

Hi @fairyto2 , 能否试着在一个干净的python3.8环境安装secretflow来执行程序，目前看上去是python的问题。我推荐使用anaconda。 感谢。

Hi @fairyto2 , I have confirmed this issue and would update here later. However, you could continue to check other examples or evaluate with official docker image.

Hi @fairyto2， 看起来是因为multiprocessing这个库在mac上面的问题，请参考https://stackoverflow.com/questions/72766345/attributeerror-cant-pickle-local-object-in-multiprocessing。 我们将会switch到[multiprocess](https://pypi.org/project/multiprocess/)以解决这个问题。 同时，我们非常感谢你发现的这一issue。Have a nice day~

Hi @bubkoo , Your attention is appreciated. Putting a svg is a good idea here.

Hi @YIYEYIYE , 1. 请查阅我们的文档：https://spu.readthedocs.io/en/beta/reference/mpc_status.html 2. spu的计算是基于mpc协议（即你前面提到的aby3等协议）。请参阅相关论文和资料了解mpc是如何计算的，以及不同协议的secret sharing schema和明密文转化流程。 3. 另外，如果你想进行同态计算，请使用secretflow的另一个子项目-heu：https://secretflow.readthedocs.io/zh_CN/latest/developer/design/heu.html

Hi @data-alexpan, We need the code and detailed outputs from your run in order to understand what has happened. Thanks.
