Save images in batch to disk in PPM format.

Useful for debugging.

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.

:keyword input_layout : layout str, optional, default = ‘HWC’: Layout of input images. :keyword preserve: Prevents the operator from being removed from the

graph even if its outputs are not used.

Keyword Arguments:

  • seed (int, optional, default = -1) –

    Random seed.

    If not provided, it will be populated based on the global seed of the pipeline.

  • suffix (str, optional, default = ‘’) – Suffix to be added to output file names.
