nvidia.dali.fn.experimental.peek_image_shape#
- nvidia.dali.fn.experimental.peek_image_shape(__input, /, *, adjust_orientation=True, bytes_per_sample_hint=[0], dtype=DALIDataType.INT64, image_type=DALIImageType.RGB, preserve=False, seed=-1, device=None, name=None)#
Obtains the shape of the encoded image.
- Supported backends
‘cpu’
- Parameters:
__input (TensorList) – Input to the operator.
- Keyword Arguments:
adjust_orientation (bool, optional, default = True) – Use the EXIF orientation metadata when calculating the shape.
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
, optional, default = DALIDataType.INT64) – Data type, to which the sizes are converted.image_type (
nvidia.dali.types.DALIImageType
, optional, default = DALIImageType.RGB) – Color format of the image.preserve (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
seed (int, optional, default = -1) –
Random seed.
If not provided, it will be populated based on the global seed of the pipeline.
