MPSCNNLossDataDescriptor(3)				 MetalPerformanceShaders.framework			       MPSCNNLossDataDescriptor(3)

NAME
       MPSCNNLossDataDescriptor

SYNOPSIS
       #import <MPSCNNLoss.h>

       Inherits NSObject, and <NSCopying>.

   Instance Methods
       (nonnull instancetype) - init

   Class Methods
       (nullable MPSCNNLossDataDescriptor *) + cnnLossDataDescriptorWithData:layout:size:

   Properties
       MPSDataLayout layout
       MTLSize size
       NSUInteger bytesPerRow
       NSUInteger bytesPerImage

Detailed Description
       This depends on Metal.framework.  The MPSCNNLossDataDescriptor specifies a loss data descriptor. The same descriptor can be used to
       initialize both the labels and the optional weights data.

Method Documentation
   + (nullable MPSCNNLossDataDescriptor*) cnnLossDataDescriptorWithData: (NSData *__nonnull) data(MPSDataLayout) layout(MTLSize) size
       Make a descriptor loss data. The bytesPerRow and bytesPerImage are automatically calculated assuming a dense array. If it is not a dense
       array, adjust bytesPerRow and bytesPerImage to the right value by changing properties.

       Parameters:
	   data The per-element loss data. The data must be in floating point format.
	   layout The data layout of loss data.
	   size The size of loss data.

       Returns:
	   A valid MPSCNNLossDataDescriptor object or nil, if failure.

   - (nonnull instancetype) init
Property Documentation
   - bytesPerImage [read],  [write],  [nonatomic],  [assign]
       Slice bytes of loss data.  This parameter specifies the slice bytes of loss data.

   - bytesPerRow [read],  [write],  [nonatomic],  [assign]
       Row bytes of loss data.	This parameter specifies the row bytes of loss data.

   - layout [read],  [nonatomic],  [assign]
       Data layout of loss data. See MPSImage.h for more information.  This parameter specifies the layout of loss data.

   - size [read],  [nonatomic],  [assign]
       Size of loss data: (width, height, feature channels}.  This parameter specifies the size of loss data.
