nvidia.dali.fn.cast — NVIDIA DALI (original) (raw)

nvidia.dali.fn.cast(__input, /, *, bytes_per_sample_hint=[0], dtype, preserve=False, device=None, name=None)#

Cast a tensor to a different type.

This operator allows sequence inputs and supports volumetric data.

Supported backends

• ‘cpu’
• ‘gpu’

Parameters:

__input¶ (TensorList) – Input to the operator.

Keyword Arguments:

• bytes_per_sample_hint¶ (int or list of int, optional, default = [0]) –
  Output size hint, in bytes per sample.
  If specified, the operator’s outputs residing in GPU or page-locked host memory will be preallocated to accommodate a batch of samples of this size.
• dtype¶ (nvidia.dali.types.DALIDataType) – Output data type.
• preserve¶ (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
