产品定位：大数据／机器学习平台
面向的用户：开发者／算法工程师
这次主要研究的是深度学习平台。
支持的框架：Tensorflow, Mxnet, Caffe
这次使用https://help.aliyun.com/document_detail/50654.html?spm=a2c4g.11186623.6.591.zC378V 平台提供的代码和数据进行了测试，按照文档可以运行起来。
但是问题是：训练产生的模型放在哪里？
训练生成的模型如何发布？
发布后，如何调用？如果做推理。
继续研究
但是出错了，具体信息如下：（需要找人看一下）

提交了工单，原来是文档描述错误，需要把代码和数据放置在目录 'oss://bucketname/'下，并且在数据源选择时 选到目录这一级。
又试了一下，运行没有问题了。
那就说明是训练是结束了，但是这个模型应该如何发布呢？或者，我想要测试一下这个模型的效果。
