采样组件运行失败

[1998zxn]

任务流如下：

样本表输入为：
泰坦尼克号遇难名单的训练集。
报错提示：

本地随意构造的数据集作为样本表的输入，反而能够正确执行。

看报错并不是由于数据规范导致失败，采样组件是否对数据有一定的要求？

[1998zxn]

数据集中存在空值无法处理。后续还有一个错误是自动设别字段时识别错误，float字段类型设置为int导致失败。

使用的是哪个版本呢？

嗯～～为什么不在数据对齐后再做采样呢。是否考虑过随机采样后求交结果可能为空呢

[1998zxn]

为什么不在数据对齐后再做采样呢==》从我的角度讲，我之前并没有很多相关经验，同时没有看到组件对输入有做相关要求（例如规范化、数据对齐等），所以直接将原始数据放了进去。
是否考虑过随机采样后求交结果可能为空呢==》对于随机采样我也没有做过了解，求交是随机采样后必须的步骤吗？当然我也在后面设置了隐私求交来获取垂直表，不过提示assert device.world_size == 2, 'only 2pc is allowed.'断言失败，还没有去调试。
