Detailed Description

Layer for loading Record from DataShard.

It is derived from DataLayer.

Member Function Documentation

void singa::ShardDataLayer::ComputeFeature	(	int	flag,
		Metric *	perf
	)

overridevirtual

Compute features of this layer based on connected layers.

Parameters

perf	pointer to Metric obj for collect and aggregate performance

Implements singa::Layer.

void singa::ShardDataLayer::Setup	(	const LayerProto &	proto,
		int	npartitions
	)

overridevirtual

Setup layer properties.

Setup the shapes for data and parameters, also setup some properties based on the layer configuration and connected layers.

Parameters

proto	layer configuration.
npartitions	num of total partitions of the original layer. This layer should be setup as one partition.

Reimplemented from singa::Layer.
