This task opens a deep learning label raster given an input URI.
            This task is part of ENVI Deep Learning, which requires a separate license and installation.
            Examples
            
            e = ENVI(/HEADLESS)
             
            
            
            File = Filepath('LabelRasterContainers.dat', $
              Subdir=['data','deep_learning'], Root_Dir=e.Root_Dir)
             
            
            Task = ENVITask('ExtractDeepLearningLabelRasterFromFile')
             
            
            Task.INPUT_URI = File
             
            
            Task.Execute
            Print, Task.OUTPUT_RASTER[0], /IMPLIED_PRINT
            Syntax
            Result = ENVITask('ExtractDeepLearningLabelRasterFromFile')
            Input properties (Set, Get): INPUT_URI, MASK_BAND
            Output properties (Get only): OUTPUT_RASTER
            Properties marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Properties marked as "Get" are those whose values you can retrieve but not set.

            DISPLAY_NAME
            NAME
            REVISION
            See the ENVITask topic in ENVI Help for details. 
            This task also contains the following properties:
            INPUT_URI (required)
            Specify a fully qualified URI to an ENVIDeepLearningLabelRaster file.
            MASK_BAND (optional)
            Label rasters should have metadata that specifies which band is the mask band, but if they don't, this parameter will allow you to specify it.
            OUTPUT_RASTER (required)
            This is the ENVIDeepLearningLabelRaster extracted from the URI.
