Unknown CUDA arch (8.9) or GPU not supported1

When I installed the “mmcv” library, the following error occurred. How do I solve this problem? [Graphics card: rtx4070; CUDA: 11.8;]" raise ValueError(“Unknown CUDA arch ({}) or GPU not supported”.format(arch))
ValueError: Unknown CUDA arch (8.9) or GPU not supported
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
