nvidia.dali.fn.peek_image_shape#

nvidia.dali.fn.peek_image_shape(__input, /, *, bytes_per_sample_hint=[0], dtype=DALIDataType.INT64, 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:

  • 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.

  • 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.

  • type (nvidia.dali.types.DALIDataType) –

    Warning

    The argument type is a deprecated alias for dtype. Use dtype instead.
