GPU 4090 error：unsupported gpu architecture 'compute_89'

As your picture shows, you use CUDA 11.3, which doesn't support sm89 compile, so you need to use sm86 instead.

Open CMakelists.txt and modify

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} 
  -gencode arch=compute_$ENV{CUDASM},code=compute_$ENV{CUDASM}
)

to

set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} 
  -gencode arch=compute_86,code=compute_86
)
