Configuration information： NVIDIA GeForce RTX 4060 Ti cuda 11.8 pytorch 2.1 At first, I thought it was due to the environment, but I switched to the same environment as the author.But the same error occurred。 NVIDIA GeForce RTX 2080 Ti
cuda 11.0 pytorch 1.7 After reviewing others' issues, I recompiled pointops (https://github.com/POSTECH-CVLab/point-transformer), but the problem still persists Help!
