[lmx-code]

目前定位到这一块有问题，能帮忙看看这个错误是因为啥吗？

[mh739025250]

@lmx-code 你跑的是哪个example

[lmx-code]

@mh739025250 横向联邦学习任务

[mh739025250]

你是用delta-all-in-one跑的吗？你运行的是哪个版本的呢？
你这个问题，看起来是一个我在0.8.1版本已经修复了的bug。

[lmx-code]

我用的是这个命令： git clone --depth 1 --branch v0.8.1 https://github.com/delta-mpc/delta-all-in-one.git拉取的，后续步骤按照文档操作的

[mh739025250]

@lmx-code
你在docker-compose up -d启动之后，
运行一下命令，docker exec -it dashboard bash，可以进入dashboard容器内的终端，
然后输入命令pip list | grep delta，把输出给我看看。

[lmx-code]

[mh739025250]

嗯，我知道了，这是deltaboard镜像里delta-task包版本的问题。
我会出再发一个小版本来修复这个问题。

[lmx-code]

好的，出完版本后跟我说下，谢谢

[mh739025250]

@ssyyxx17410103151207 你的问题和 @lmx-code 是一样的吗？我看你的日志没给出报错的位置。

[mh739025250]

@lmx-code 0.8.3版本已经发布了，修复了你提到的问题，你可以试一下

[zhaosiyu-alt]

您好，我在8.3版本中进行了无区块链网络搭建，尝试运行横向联邦学习任务，在日志中仍然显示ERROR而且最后的运行状态是异常，请问是为什么？（是不是因为只有两个delta-node节点，而minst数据集被分为三份，需要三个delta-node节点？）

以下是日志内容：

用delta-all-in-one的0.8.3版本跑横向联邦学习任务还是有这个问题
