Class TensorShort

Represents data in a multidimensional array-like structure.

Ownership and lifetime:

  • Disposed needs to be called on the main thread.
  • Ownership is always to the owner of the object.

Data Representation:

  • TensorShape represents the data layout of the tensor
  • Data is held by a tensorData (ITensorData) which can be on a given backend
  • Data is stored in a flattened row major format
  • Data can be pending (ie computation is being done in parallel)
    • call CompleteAllPendingOperations for a blocking call to finish computing the tensor's data
    • call CompleteOperationsAndDownloadAsync/ReadbackRequest for a non blocking call to finish computing the tensor's data Data can be in a non readable type (GPU/NPU)
    • Call CompleteOperationsAndDownload to make the tensor readable (this will fetch the data on the backend and convert it to a readable format)
    • CompleteOperationsAndDownload is a blocking call if called on its own. for a non blocking call, make sure that CompleteOperationsAndDownloadAsync/ReadbackRequest have been called previously you can check that with IsReadbackRequestDone

Data manipulation

  • ToReadOnlyArray returns a copy of the tensor's data
  • dataOnBackend can be manipulated directly to avoid a unnecessary copy see ComputeTensorData/BurstTensorData for info
