MPSNNStateNode
SYNOPSIS
#import <MPSNNGraphNodes.h>
Inherits NSObject.
Inherited by MPSNNBinaryGradientStateNode, MPSNNGradientStateNode, and MPSNNLabelsNode.
Instance Methods
(nonnull instancetype) - init
Properties
id< MPSHandle > handle
BOOL exportFromGraph
BOOL synchronizeResource
Detailed Description
A placeholder node denoting the position in the graph of a MPSState object Some filters need additional information about an image in
order to function. For example a max-pooling gradient filter needs to know which position the max result came from in the original pooling
filter in order to select the right data for gradient computation. In other cases, state may be moved into a MPSState object in order to
keep the filter itself immutable. The MPSState object typically encapsulates one or more MTLResource objects.
Method Documentation
- (nonnull instancetype) init
Property Documentation
- (BOOL) exportFromGraph [read], [write], [nonatomic], [assign]
Tag a state node for view later Most state nodes are private to the graph. These alias memory heavily and consequently generally have
invalid state when the graph exits. When exportFromGraph = YES, the image is preserved and made available through the [MPSNNGraph encode...
resultStates:... list.
CAUTION: exporting an state from a graph prevents MPS from recycling memory. It will nearly always cause the amount of memory used by the
graph to increase by the size of the state. There will probably be a performance regression accordingly. This feature should generally be
used only when the node is needed as an input for further work and recomputing it is prohibitively costly.
Default: NO
- (id<MPSHandle>) handle [read], [write], [nonatomic], [retain]
MPS resource identification See MPSHandle protocol reference. Default: nil
- (BOOL) synchronizeResource [read], [write], [nonatomic], [assign]
Set to true to cause the resource to be synchronized with the CPU Ignored on non-MacOS.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

hi,
I am searching for a native tool on MacOS that can increase the resolution of a group of image files whose aspect ratios (file width versus height) vary widely. There are numerous files so I don't wish to do this manually. Someone suggested the sips command with the resampling option but... (5 Replies)

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
