Constructors

TensorNDIterator(TensorNDIterator)

Returns a copy of another TensorNDIterator.

Declaration
public TensorNDIterator(TensorNDIterator other)
Parameters
Type Name Description
TensorNDIterator other

TensorNDIterator(TensorShape)

Initializes and returns an instance of TensorNDIterator with a given shape.

Declaration
public TensorNDIterator(TensorShape shape)
Parameters
Type Name Description
TensorShape shape

TensorNDIterator(TensorShape, Int32)

Initializes and returns an instance of TensorNDIterator with a given shape, and uses a given index in the flattened 1D version of the shape.

Declaration
public TensorNDIterator(TensorShape shape, int index)
Parameters
Type Name Description
TensorShape shape
Int32 index

Fields

index

The 1D flattened index.

Declaration
public int index
Field Value
Type Description
Int32

Properties

Item[Int32]

Gets or sets the iterator at a given axis.

Declaration
public int this[int axis] { get; set; }
Parameters
Type Name Description
Int32 axis
Property Value
Type Description
Int32

shape

The shape that is iterated over.

Declaration
public readonly TensorShape shape { get; }
Property Value
Type Description
TensorShape

Methods

Broadcast(TensorShape)

Creates a new iterator by broadcasting this iterator on a given shape following the broadcast rule.

Declaration
public TensorNDIterator Broadcast(TensorShape shapeToBroadcast)
Parameters
Type Name Description
TensorShape shapeToBroadcast
Returns
Type Description
TensorNDIterator

CopyNDIndex(TensorNDIterator)

Copies the dimension indices from another iterator. If the shapes of the iterators are not the same the final flattened index may be different.

Declaration
public void CopyNDIndex(TensorNDIterator other)
Parameters
Type Name Description
TensorNDIterator other

HasNext()

Whether the iterator is yet to reach the end of the shape.

Declaration
public bool HasNext()
Returns
Type Description
Boolean

HasNext(Int32)

Whether the iterator is yet to reach the end of the shape on a given axis.

Declaration
public bool HasNext(int axis)
Parameters
Type Name Description
Int32 axis
Returns
Type Description
Boolean

MoveNext()

Increments the flattened index by one.

Declaration
public void MoveNext()

MoveNextAxis(Int32)

Increments the index at a given axis by one.

Declaration
public void MoveNextAxis(int axis)
Parameters
Type Name Description
Int32 axis

RemoveDim(Int32)

Creates a new iterator by skipping an axis of this iterator.

Declaration
public TensorNDIterator RemoveDim(int axis)
Parameters
Type Name Description
Int32 axis
Returns
Type Description
TensorNDIterator

Reset()

Resets the iterator to the start of the shape.

Declaration
public void Reset()

ToString()

Returns a string that represents the TensorNDIterator.

Declaration
public override string ToString()
Returns
Type Description
String
Overrides

Transpose()

Creates a new iterator by transposing this iterator reversing the axes.

Declaration
public TensorNDIterator Transpose()
Returns
Type Description
TensorNDIterator

Transpose(Int32[])

Creates a new iterator by transposing this iterator using the given permutations.

Declaration
public TensorNDIterator Transpose(int[] permutations)
Parameters
Type Name Description
Int32[] permutations
Returns
Type Description
TensorNDIterator
