- nvidia.dali.fn.cat(*inputs, **kwargs)¶
Joins the input tensors along an existing axis.
The shapes of the inputs must match in all dimensions except the concatenation axis.
- Supported backends
input0 (TensorList) – Input to the operator.
input[1..998] (TensorList, optional) – This function accepts up to 998 optional positional inputs
- Keyword Arguments:
axis (int, optional, default = 0) –
Axis along which the input tensors are concatenated.
Accepted range is [-ndim, ndim-1]. Negative indices are counted from the back.
axis_name (str, optional) –
Name of the axis along which the tensors are concatenated.
This argument is mutually exclusive with
axis. This argument requires that at least one input has a non-empty layout and that all non-empty input layouts match.
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.
