failing to build wheel on 312

[Ryang20718]

hitting some issues with trying to build the latest wheel 2.3.6 on python 3.12 on cuda 12.2 with arch 6.1 when trying to build the wheel locally. Wondering if you had any insights here?

error: calling a __device__ function("__expf") from a __host__ __device__ function("fast_exp") is not allowed

Have you solved this problem now？ @Ryang20718

I met the same problem and finally solved. Check you cumm version, it should not be higher than 0.4.11. Meanwhile, cumm(v0.4.11) can't support latest cuda. I recommend you use cumm cuda 11.8, cumm v0.4.11, which I have tested on Ubuntu 22.04. @Ryang20718 @TaylorThunderboltLethers
