nvidia.dali.fn.noise.gaussian¶
-
nvidia.dali.fn.noise.
gaussian
(*inputs, **kwargs)¶ 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 provided, it will be populated based on the global seed of the pipeline.
stddev (float or TensorList of float, optional, default = 1.0) – Standard deviation of the distribution.
