pythonluigi意外死亡，退出代码为11

Question

我有一个带有luigi的数据管道，如果我把一个worker放到任务中，它就可以正常工作。但是，如果我放置了>；1个worker，那么它将在一个包含2个依赖项的阶段中死亡（意外地退出代码为-11）。代码相当复杂，因此很难给出最小的示例。问题的要点是我正在用gensim做以下事情：

1. 从一些文本中建立词典。在
2. 根据所述文本和词典建立语料库（需要（1））。在
3. 从语料库和词典中训练LDA模型（需要（1）和（2））。在

由于某些原因，每次我放置多个工人时，步骤（3）都会崩溃，即使（1）和（2）已经完成。。。在

任何帮助将不胜感激！在

编辑：这里是一个日志记录信息的示例。TrainLDA是任务（3）。之后还有两项任务需要TrainLDA。所有先前的任务都正确完成。我用TrainLDA的参数替换了...，这样输出就更可读了。附加信息只是print我们用来帮助我们知道发生了什么的声明。在
