Description

Is this a new feature, an improvement, or a change to existing functionality?

New Feature

How would you describe the priority of this feature request

Should have (e.g. Adoption is possible, but the performance shortcomings make the solution inferior).

Please provide a clear description of problem this feature solves

Hi,

I was wondering why DALI did not accept complex numbers dtypes? It would great to load data directly in complex dtype! To circumvent I append a channel dimension with length 2.

Thanks :)
