Returns
List of input tensors.

Implements tvm::te::OperationNode.

◆ num_outputs()

int tvm::te::ScanOpNode::num_outputs ( ) const
finalvirtual
Returns
number of outputs

Implements tvm::te::OperationNode.

◆ output_dtype()

DataType tvm::te::ScanOpNode::output_dtype ( size_t  i) const
finalvirtual

Get data type. i-th output tensor.

Parameters
iThe output index.
Returns
type of i-th output.

Implements tvm::te::OperationNode.

◆ output_shape()

Parameters
iThe output index.
Returns
shape of i-th output.

staticconstexpr

◆ init

Array<Tensor> tvm::te::ScanOpNode::init

the initialization tensors

◆ inputs

Array<Tensor> tvm::te::ScanOpNode::inputs

the inputs to the scan, these are optionally provided But they can be helpful to provide hints to speedup get of scan body.

◆ scan_axis

IterVar tvm::te::ScanOpNode::scan_axis

IterVar to scan over.

◆ spatial_axis_

Array<IterVar> tvm::te::ScanOpNode::spatial_axis_

Spatial axis to indicate spatial dimension of each output. They corresponds to flattened spatial axis of the outputs.

[output[0].axis[1], output[0].axis[2]... output[k].axis[j]...] These are auxiliary data structure for storing result of bound inference. They do not corresponds to splittable iterations, thus the name comes with underscore.

◆ state_placeholder

Array<Tensor> tvm::te::ScanOpNode::state_placeholder

The placeholder to refer as states in update.

◆ update

Array<Tensor> tvm::te::ScanOpNode::update

the update function represented by tensor
