- nvidia.dali.fn.sequence_rearrange(*inputs, **kwargs)¶
Rearranges frames in a sequence.
Assumes that the outermost dimension represents the frame index in the sequence. If the input has a non-empty layout description, it must start with
This operator allows sequence inputs.
- Supported backends
input (TensorList) – Input to the operator.
- Keyword Arguments:
new_order (int or list of int or TensorList of int) –
List that describes the new order for the elements in each sample.
Output sequence at position
iwill contain element
new_order[i]from input sequence:
out[i, ...] = in[new_order[i], ...]
Elements can be repeated or dropped, but empty output sequences are not allowed. Only indices in
[0, input_outermost_extent)are allowed to be used in
new_order. Can be specified per sample as 1D tensors.
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.
