- nvidia.dali.fn.permute_batch(*inputs, **kwargs)¶
Returns a batch of tensors constructed by selecting tensors from the input based on indices given in
out_tensor[i] = in_tensor[indices[i]]
- Supported backends
input (TensorList) – Input to the operator.
- Keyword Arguments:
indices (int or list of int or TensorList of int) –
List of indices, matching current batch size, or a batch of scalars representing indices of the tensors in the input batch.
The indices must be within
[0..batch_size)range. Repetitions and omissions are allowed.
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.
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.
