Azure ML ModelManagement Web服务更新

NOTICE: Azure Machine Learning Workbench (Preview) is deprecated. The workflow for deploying models, images and services has been updated since this question was posted.

我一直在使用Azure机器学习工作台（预览版）为Azure机器学习服务开发机器学习模型 . 我成功地将模型部署为Web服务，如Azure Machine Learning Documentation (Preview)中所述 . 我已设法启动并运行服务，并且模型，清单和图像都已正确配置 . 到现在为止还挺好 .

但现在我已经到了我希望能够使用新配置更新服务的阶段 . 这就是我发现自己有更多问题而不是答案的地方 .

我发现我可以

• 配置新模型

• 配置指向该模型的新清单

• 配置指向该清单的新图像

• 更新现有（或创建新）服务以指向新图像

这似乎足够合理 . 但是如果我只需要更新清单，是否可以跳过新模型的配置（1），并从上面的（2）开始更新，并让它指向现有模型而不是新模型一？

我当然通过从CLI调用以下内容来尝试这一点，并且我遇到了以下输出：

}

如果我尝试回滚到上一个清单，则没有错误消息，一切正常 . 这让我觉得我的新清单和/或图像有问题 . 但是，创建它们时没有警告或错误 .

我试过搜索错误消息，但我一无所获 .
