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.
