nvidia.dali.fn.noise.gaussian — NVIDIA DALI (original) (raw)

nvidia.dali.fn.noise.gaussian(__input, /, *, bytes_per_sample_hint=[0], mean=0.0, preserve=False, seed=-1, stddev=1.0, device=None, name=None)#

Applies gaussian noise to the input.

The shape and data type of the output will match the input.

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.
• mean¶ (float or TensorList of float, optional, default = 0.0) – Mean of the distribution.
• 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 set, one will be assigned automatically.
• stddev¶ (float or TensorList of float, optional, default = 1.0) – Standard deviation of the distribution.
