.SH "Detailed Description"
.PP 
This depends on Metal\&.framework\&.  The \fBMPSCNNLossDataDescriptor\fP specifies a loss data descriptor\&. The same descriptor can be used to initialize both the labels and the optional weights data\&. 
.SH "Method Documentation"
.PP 
.SS "+ (nullable \fBMPSCNNLossDataDescriptor\fP*) cnnLossDataDescriptorWithData: (NSData *__nonnull) data(\fBMPSDataLayout\fP) 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\&. 
.PP
\fBParameters:\fP
.RS 4
\fIdata\fP The per-element loss data\&. The data must be in floating point format\&. 
.br
\fIlayout\fP The data layout of loss data\&. 
.br
\fIsize\fP The size of loss data\&.

\fBReturns:\fP
.RS 4
\fBA\fP valid \fBMPSCNNLossDataDescriptor\fP object or nil, if failure\&.

.SS "\- bytesPerImage\fC [read]\fP, \fC [write]\fP, \fC [nonatomic]\fP, \fC [assign]\fP"
Slice bytes of loss data\&.  This parameter specifies the slice bytes of loss data\&. 
.SS "\- bytesPerRow\fC [read]\fP, \fC [write]\fP, \fC [nonatomic]\fP, \fC [assign]\fP"
Row bytes of loss data\&.  This parameter specifies the row bytes of loss data\&. 
.SS "\- layout\fC [read]\fP, \fC [nonatomic]\fP, \fC [assign]\fP"
Data layout of loss data\&. See MPSImage\&.h for more information\&.  This parameter specifies the layout of loss data\&. 
.SS "\- size\fC [read]\fP, \fC [nonatomic]\fP, \fC [assign]\fP"
Size of loss data: (width, height, feature channels}\&.  This parameter specifies the size of loss data\&.
