- nvidia.dali.fn.batch_permutation(*inputs, **kwargs)¶
Produces a batch of random integers which can be used as indices for indexing samples in the batch.
- Supported backends
- Keyword Arguments:
allow_repetitions (bool, optional, default = False) – If true, the output can contain repetitions and omissions.
bytes_per_sample_hint (int or list of int, optional, default = ) –
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.
no_fixed_points (bool, optional, default = False) – If true, the the output permutation cannot contain fixed points, that is
out[i] != i. This argument is ignored when batch size is 1.
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) –
If not provided, it will be populated based on the global seed of the pipeline.
