Detailed Description
Layer type for shuffling data.
This class shuffles data by applying in sequence: a transpose operation, a reshape operation and a second transpose operation. The dimension types of the output are those of the reshape dimension.
The layer has an optional second input. If present, it must be a 1D Int32 shape tensor, and the reshape dimensions are taken from it.
- Warning
- Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
Member Function Documentation
◆ getFirstTranspose()
|
pure virtual |
Get the permutation applied by the first transpose operation.
- Returns
- The dimension permutation applied before the reshape.
- See also
- setFirstTranspose
◆ getReshapeDimensions()
|
pure virtual |
Get the reshaped dimensions.
- Returns
- The reshaped dimensions.
If there is a second input, returns Dims with nbDims == -1.
◆ getSecondTranspose()
|
pure virtual |
Get the permutation applied by the second transpose operation.
- Returns
- The dimension permutation applied after the reshape.
- See also
- setSecondTranspose
◆ setFirstTranspose()
|
pure virtual |
Set the permutation applied by the first transpose operation.
- Parameters
-
permutation The dimension permutation applied before the reshape.
The default is the identity permutation.
- See also
- getFirstTranspose
◆ setInput()
|
pure virtual |
Relaxes ILayer::setInput to allow appending a second input.
Like ILayer::setInput, but additionally works if index==1, nbInputs()==1, and there is no implicit batch dimension, in which case nbInputs() changes to 2.
When there is a 2nd input, the reshapeDimensions are taken from it, overriding the dimensions supplied by setReshapeDimensions.
Implements nvinfer1::ILayer.
◆ setReshapeDimensions()
|
pure virtual |
Set the reshaped dimensions.
- Parameters
-
dimensions The reshaped dimensions.
Two special values can be used as dimensions.
Value 0 copies the corresponding dimension from input. This special value can be used more than once in the dimensions. If number of reshape dimensions is less than input, 0s are resolved by aligning the most significant dimensions of input.
Value -1 infers that particular dimension by looking at input and rest of the reshape dimensions. Note that only a maximum of one dimension is permitted to be specified as -1.
The product of the new dimensions must be equal to the product of the old.
If there is a second input, i.e. reshape dimensions are dynamic, calling setReshapeDimensions() is an error and does not update the dimensions.
◆ setSecondTranspose()
|
pure virtual |
Set the permutation applied by the second transpose operation.
- Parameters
-
permutation The dimension permutation applied after the reshape.
The default is the identity permutation.
The permutation is applied as outputDimensionIndex = permutation.order[inputDimensionIndex], so to permute from CHW order to HWC order, the required permutation is [1, 2, 0].
