Constructors

UnsafeArrayTensorData(int)

Create UnsafeArrayTensorData with new array

Declaration
public UnsafeArrayTensorData(int count)
Parameters
Type Name Description
int count

element count to reserve

UnsafeArrayTensorData(float[], int, int, bool)

Create UnsafeArrayTensorData from supplied array

Declaration
protected UnsafeArrayTensorData(float[] data, int offset = 0, int count = -1, bool isReadonly = false)
Parameters
Type Name Description
float[] data

data
int offset

offset in data
int count

element count
bool isReadonly

read-only flag

UnsafeArrayTensorData(ArrayTensorData)

Create UnsafeArrayTensorData and use shared array

Declaration
public UnsafeArrayTensorData(ArrayTensorData sharedArray)
Parameters
Type Name Description
ArrayTensorData sharedArray

shared array

UnsafeArrayTensorData(SharedArrayTensorData)

Create UnsafeArrayTensorData and use shared array

Declaration
public UnsafeArrayTensorData(SharedArrayTensorData sharedArray)
Parameters
Type Name Description
SharedArrayTensorData sharedArray

shared array

UnsafeArrayTensorData(TensorShape)

Create UnsafeArrayTensorData with new array

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

shape

Methods

Dispose()

Dispose

Declaration
public override void Dispose()
Overrides

Download(TensorShape)

Returns an array filled with the values of a tensor. Depending on the implementation and underlying device this array might be a copy or direct reference to the tensor values. This is a blocking call, unless data from device was requested via ScheduleAsyncDownload beforehand and has already arrived.

Declaration
public override float[] Download(TensorShape shape)
Parameters
Type Name Description
TensorShape shape

the TensorShape (and thus length) of the data to copy
Returns
Type Description
float[]

Tensor data as float arrary
Overrides

~UnsafeArrayTensorData()

Finalizer

Declaration
protected ~UnsafeArrayTensorData()

Reserve(int)

Reserve uninitialized memory.

Declaration
public override void Reserve(int count)
Parameters
Type Name Description
int count

element count to reserve
Overrides

ToString()

Summary

Declaration
public override string ToString()
Returns
Type Description
string

summary
Overrides

Upload(float[], TensorShape, int)

Initialize with data. shape is the TensorShape (and thus length) of the data to copy. managedBufferStartIndex is the offset where to start the copy in the data

Declaration
public override void Upload(float[] data, TensorShape shape, int managedBufferStartIndex = 0)
Parameters
Type Name Description
float[] data

data as float array
TensorShape shape

Tensor shape
int managedBufferStartIndex

managed buffer start index
