getOutputType
public InputType getOutputType(int layerIndex, InputType inputType)
Description copied from class:Layer
For a given type of input to this layer, what is the type of the output?- Specified by:
getOutputType
in classLayer
- Parameters:
layerIndex
- Index of the layerinputType
- Type of input for the layer- Returns:
- Type of output from the layer
-

- Null if no preprocessor is required, otherwise the type of preprocessor necessary for this layer/input combination
-
getMemoryReport
public LayerMemoryReport getMemoryReport(InputType inputType)
Description copied from class:Layer
This is a report of the estimated memory consumption for the given layer- Specified by:
getMemoryReport
in classLayer
- Parameters:
inputType
- Input type to the layer. Memory consumption is often a function of the input type- Returns:
- Memory report for the layer
-
setNIn
public void setNIn(InputType inputType, boolean override)
Description copied from class:Layer
Set the nIn value (number of inputs, or input channels for CNNs) based on the given input type- Overrides:
setNIn
in classNoParamLayer
- Parameters:
inputType
- Input type for this layeroverride
- If false: only set the nIn value if it's not already set. If true: set it regardless of whether it's already set or not.
