Stack

cvcuda.stack(src: list[nvcv.Tensor], *, stream: Optional[nvcv.cuda.Stream] = None) → nvcv.Tensor

Executes the Stack operation on the given cuda stream. This takes input tensors and combines them into a N(HWC/CHW) tensor.

See also

Refer to the CV-CUDA C API reference for the Stack operator for more details and usage examples.

Parameters

src (List[nvcv.Tensor]) – Input tensors containing one or more samples each images all tensors must be N(HWC/CHW) or HWC/CHW and have the same data type and shape.
stream (nvcv.cuda.Stream, optional) – CUDA Stream on which to perform the operation.

Returns

The output tensor containing the stacked input tensors.

Return type

nvcv.Tensor

Caution

Restrictions to several arguments may apply. Check the C API references of the CV-CUDA operator.

cvcuda.stack_into(dst: nvcv.Tensor, src: list[nvcv.Tensor], *, stream: Optional[nvcv.cuda.Stream] = None) → nvcv.Tensor

Executes the Stack operation on the given cuda stream. This takes input tensors and combines them into a N(HWC/CHW) tensor.
