compute capability mismatch for device 0: wanted 7.5, have 8.6

[xlhuang132]

hello,
I run "CUDA_ARCH=86 pip install libKMCUDA" successfully but when I try to run the program it tells me this:

compute capability mismatch for device 0: wanted 7.5, have 8.6
>>>> you may want to build kmcuda with -DCUDA_ARCH=86 (refer to "Building" in README.md)
compute capability mismatch for device 1: wanted 7.5, have 8.6
>>>> you may want to build kmcuda with -DCUDA_ARCH=86 (refer to "Building" in README.md)
python-BaseException

ValueError: No such CUDA device exists
Backend TkAgg is interactive backend. Turning interactive mode on. 

so it does not support 8.6? or I need to use these commands:

git clone https://github.com/src-d/kmcuda
cd src
cmake -DCMAKE_BUILD_TYPE=Release -D DISABLE_R-y -D CUDA_ARCH=86 . && make

I tried these commands

git clone https://github.com/src-d/kmcuda
cd src
cmake -DCMAKE_BUILD_TYPE=Release -D DISABLE_R-y -D CUDA_ARCH=86 . && make

and got this
