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.

  • input_layout (layout str, optional, default = ‘HWC’) – Layout of input images.

  • preserve (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.

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