Hi @south-ocean,

Thank you for reaching out. I see that the offending lines are redundant and can be safely removed (https://github.com/NVIDIA/DALI/pull/5653). Also, they are wrapped around by #ifdef __CUDA_ARCH__ that should evaluate to false for the host code. Can you tell me more about your development environment (host and CUDA compiler versions)?

Hello @south-ocean There's something very nonstandard in your setup. The offending #include is guarded with #ifdef __CUDA_ARCH__. __CUDA_ARCH__ should not be defined in a translation unit types.cc, which should not be compiled with NVCC.
