virtual |
Setup layer properties.
Setup the shapes for data and parameters, also setup some properties based on the layer configuration and connected src layers.
srclayers | layers connecting to this layer |
Implements singa::Layer.
|
virtual |
Setup the layer properties except shape.
The shape is already set and passed in to set other properties. properties are set according to shapes of itself and connected layers, and configuration. this should not change the current shape_( shape check is done outside the function).
Implements singa::Layer.
