Problem running with AMD CPU icd

[malakudi]

Trying to run with AMD CPU icd for some test on my Ryzen 1700X. I get the following error:

Code:

./hashcat64.bin --opencl-platform=2 -b  hashcat (v4.0.1) starting in benchmark mode... Benchmarking uses hand-optimized kernel code by default. You can use it in your cracking session by setting the -O option. Note: Using optimized kernel code limits the maximum supported password length. To disable the optimized kernel code in benchmark mode, use the -w option. OpenCL Platform #1: NVIDIA Corporation, skipped or no OpenCL compatible devices found.

Any hint?
