[jira] [Created] (MXNET-689) Add DataDesc to MXNet Scala pkg

Qing Lan created MXNET-689:
------------------------------

             Summary: Add DataDesc to MXNet Scala pkg
                 Key: MXNET-689
                 URL: https://issues.apache.org/jira/browse/MXNET-689
             Project: Apache MXNet
          Issue Type: New Feature
            Reporter: Qing Lan


Depreciate the `provideData` and `provideLabel` functions to provide `DataDesc` type instead of `ListMap[String, Shape]` type.

 

There were several issues regarding to this since v0.12 on Scala. Several users reported that the `implicit def ListMap2Descs` helps to do some downcasting job however missing information during this process (layout property).

MXNet Python language has already change this part into `DataDesc`. In that case, I plan to add two more methods that will take `DataDesc` and depreciate the functions that mentioned above. The downcasting method `ListMap2Descs` will also be depreciated and not to be used in current MXNet Scala code base.
