我正在尝试部署引擎。我正在关注文档。所以我：

  • 创建应用程序，
  • 下载引擎，
  • 更新应用程序名称engine.json，
  • 建造它：pio build --verbose,
  • 然后训练：pio train --verbose。

一切正常，构建成功完成。但是，训练总是失败并出现错误：

[ERROR] [CreateWorkflow$] WorkflowConfig is empty. Quitting

我尝试下载另一个引擎，但错误是一样的。互联网上没有关于WorkflowConfig. 有谁知道可能出了什么问题？

我在下面附上了 pio.log 内容。

这是一个已知问题，并在下一个版本中修复。在此处查看 JIRA 票证：https ://predictionio.atlassian.net/browse/PDIO-636

你现在只需要省略 --verbose 。
