Member Function Documentation

void singa::MnistLayer::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.
