> 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.
