Interface ITensorData
Interface for device dependent representation of Tensor data.
Syntax
public interface ITensorData : IDisposable
Methods
Download(Int32)
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.
count is the number of elements to readback. count can be less or equal to the number of elements in a specific tensor.
Declaration
float[] Download(int count)
Parameters

| Int32 |
count |

Returns
GetMaxCount()
Return the maximum number of element this tensorData can contain.
Declaration
Returns
Reserve(Int32)
Reserve uninitialized memory.

| Int32 |

ScheduleAsyncDownload(Int32)
Schedule an asynchronous download from device memory.
count is the number of element to readback.
returns false until data from device arrives to CPU and is ready for access.
Declaration
bool ScheduleAsyncDownload(int count)
Parameters

| Int32 |

Returns
SharedAccess(out Int32)
Returns an array filled with the values of multiple tenors that share the same tensorData on device.
This function outputs offset from the beginning of the array to location of values for specific tensor. offset paramater is specified in float elements.
Depending on the implementation and underlying device this array might be a copy or direct reference to tensor values.
This is a blocking call, unless data from device was requested via ScheduleAsyncDownload beforehand and has already arrived.
Declaration
float[] SharedAccess(out int offset)
Parameters
| Type |
Name |
Description |
| Int32 |
offset |
|
Returns
Upload(Single[], Int32, Int32)
Initialize with data.
offset is the offset where to start the copy in the data
count is the number of element to copy. If count is -1 (default) number of element will be (data.length - offset).
Declaration
void Upload(float[] data, int offset = 0, int count = -1)
