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.
