在 H2O 蒸汽预测服务生成器中使用 MOJOS
Using MOJOS in H2O Steam Prediction Service Builder
在 h2o 的 Steam 预测服务生成器文档中，here, it says that the service builder can compile both h2o pojos (.java files) and mojos (downloaded from h2o flow in my case as a .zip (version 3.10.5.2), which I have been using in the manner shown here)。但是，做这样的事情：
出现此错误：
Problem accessing /makewar. Reason:
Compilation of pojo failed exit value 1 warning: [options] bootstrap class path not set in conjunction with -source 1.6
error: Class names, 'drf_denials_v4.zip', are only accepted if annotation processing is explicitly requested
1 error
1 warning
那么如何在 servicec 构建器中使用 mojo 文件呢？我是否需要使用 h2o flow 中的 "exported" 模型文件而不是 "downloaded" zip 文件？我需要使用 mojos 而不是 .java pojos 的原因是我的模型太大而不适合从 [=19= 下载的 pojo ].
更新:
正在尝试通过以下命令使用 CLI：
$ curl -X POST --form mojo=@drf_denials_v4.zip --form jar=@h2o-genmodel.jar localhost:55000/makewar > drf_denials_v4.war

cli pojo example 有效，但尝试使用我的 mojo zip 无效。
遗憾的是，UI 尚未针对 mojo 功能进行更新。但是，您可以使用命令行使用 mojos 构建 war 文件。
运行 来自您的命令行：
curl -X POST --form mojo=drf_denials_v4.zip --form jar=h2o-genmodel.jar localhost:55000/makewar > example.war
然后 运行 以正常方式 war 文件。
