在h2o
的Steam预测服务构建器文档here中,它表示服务构建器可以编译h2o
pojo
s(。 java文件)和mojo
s(在我的情况下从h2o flow
下载为.zip(版本3.10.5.2),我一直以here所示的方式使用)。但是,做这样的事情:
给出了这个错误:
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 builder中使用mojo文件呢?我是否需要使用"导出"来自h2o flow
的模型文件而不是"已下载的" zip文件?我需要使用mojo
而不是.java pojo
的原因是我的模型太大而无法放入pojo
可从h2o flow
下载。
更新:
尝试使用CLI命令:
$ 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不会。
答案 0 :(得分:1)
不幸的是,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。
从命令行运行:
{{1}}
然后以正常方式运行war文件。
