Remarks

A tensor is a multi-dimensional array of values. An 8-bit unsigned integer tensor is a tensor of 8-bit unsigned integer values.

The layout of tensors is row-major, with tightly packed contiguous data representing each dimension. The total size of a tensor is the product of the size of each dimension.

Windows Server

To use this API on Windows Server, you must use Windows Server 2019 with Desktop Experience.

Thread safety

This API is thread-safe.

Properties

Kind

The kind of the feature.

Shape

Returns the count and size of each dimension.

TensorKind

Returns the data type of the tensor.

Methods

Close()

If there are no outstanding IMemoryBufferReference objects created from this object, Close will dispose of the object and destroy its associated resources. Otherwise, Close will detach itself from its associated resources and they will be destroyed when the last IMemoryBufferReference is closed.

Create()

Creates an 8-bit unsigned integer tensor object without allocating a buffer.

Create(IIterable<Int64>)

Creates an 8-bit unsigned integer tensor object and allocates a buffer of size shape.

CreateFromArray(IIterable<Int64>, Byte[])

Creates an 8-bit unsigned integer tensor object, allocates a buffer of size shape, and copies all of data into it.

CreateFromBuffer(Int64[], IBuffer)

Creates an 8-bit unsigned integer tensor object with the given shape and uses the underlying buffer in buffer for subsequent evaluation.

CreateFromIterable(IIterable<Int64>, IIterable<Byte>)

Creates an 8-bit unsigned integer tensor object, allocates a buffer of size shape, and copies all of data into it.

CreateFromShapeArrayAndDataArray(Int64[], Byte[])

Creates an 8-bit unsigned integer tensor object, allocates a buffer of size shape, and copies all of data into it.

CreateReference()

Returns an IMemoryBufferReference representation of the buffer backing the 8-bit unsigned tensor object.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

GetAsVectorView()

Returns a read-only view of the data.
