PredictionIO 0.12.1-未找到发动机。您的生成可能已失败。流产

我已经使用二进制发行版安装了PredictionIO 0.12.1，我已经成功地启动了pio。之后，我使用了快速入门-电子商务推荐引擎模板。在生成时，我收到错误消息“[Error][Engine$]未找到引擎。您的生成可能已失败。正在中止。”

在与二进制发行版斗争之后，我下载了源代码并构建了具有所需依赖性的二进制文件

这是一个许可问题。我正在使用Ubuntu18.04，我需要提供对特定模板文件夹的读取权限（在本例中为MyeCommerceRecommension）

在得到许可后，它工作得很好

谢谢，

您可以在部署时指定引擎实例id，在培训完成后通过灰显EngineInstaceId可以获得该id。

您是否错过了下载引擎和设置

引擎.json

的步骤？它的源代码托管在GitHub的某个地方，具体取决于您使用的引擎。Nope。我已经正确下载了引擎。
