Compute gradients from this tensor to the source tensors.

Declaration

Swift

public func backward<S: Sequence>(to tensors: S, streamContext: StreamContext? = nil)
where S.Element: DynamicGraph.AnyTensor

Parameters

`to`	The source tensors to this tensor.
`streamContext`	The stream context to perform such operation.


                    
                    
                    backward(to:streamContext:)

Compute gradients from this tensor to the source tensor.

Declaration

                    permuted(_:)

Create a new tensor variable with dimensions permuted.

Declaration

Swift

public func permuted(_ indices: Int...) -> Self

Parameters


                                indices

The indices for dimensions from the original tensor. For example, a [2, 3, 4] tensor with [2, 0, 1] indices will permute to a [4, 2, 3] tensor.

Return Value

The new tensor variable with dimensions permuted.

  strides: TensorShape? = nil
) -> Self


                    
                    
                    reshaped(_:offset:strides:)

Create a new tensor representing the same variable but with different sizes.

Declaration

Swift

public func reshaped(
  _ shapeFormat: TensorShapeFormat, offset: TensorShape? = nil, strides: TensorShape? = nil
) -> Self

Parameters

`shapeFormat`	New format and shape for the tensor.
`offset`	Whether offset on each shape.
`strides`	The stride on each shape.

                    as(of:)

Explicitly cast the underlying storage to a specific type. It is a helper function than doing DynamicGraph.Tensor(something). Less code change required if we change this from tensor to group.

Declaration
