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.
|
pure virtual |
Get the permutation applied by the first transpose operation.
|
pure virtual |
Get the reshaped dimensions.
If a second input is present and non-null, or setReshapeDimensions has not yet been called, this function returns Dims with nbDims == -1.
|
pure virtual |
Get the permutation applied by the second transpose operation.
|
pure virtual |
Get meaning of 0 in reshape dimensions.
|
pure virtual |
Set the permutation applied by the first transpose operation.
permutation | The dimension permutation applied before the reshape. |
The default is the identity permutation.
|
pure virtual |
Append or replace an input of this layer with a specific tensor.
index | the index of the input to modify. |
tensor | the new input tensor Sets the input tensor for the given index. The index must be 0 for a static shuffle layer. A static shuffle layer is converted to a dynamic shuffle layer by calling setInput with an index 1. A dynamic shuffle layer cannot be converted back to a static shuffle layer. |
For a dynamic shuffle layer, the values 0 and 1 are valid. The indices in the dynamic case are as follows:
Index | Description 0 | Data or Shape tensor to be shuffled. 1 | The dimensions for the reshape operation, as a 1D Int32 shape tensor.
If this function is called with a value 1, then the function getNbInputs() changes from returning 1 to 2.
Implements nvinfer1::ILayer.

pure virtual |
Set the reshaped dimensions.
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 the second input is set, it is reset to null.
|
pure virtual |
Set the permutation applied by the second transpose operation.
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].

Set meaning of 0 in reshape dimensions.
If true, then a 0 in the reshape dimensions denotes copying the corresponding dimension from the first input tensor. If false, then a 0 in the reshape dimensions denotes a zero-length dimension.
Default: true
