CUDA kernel failed: an illegal memory access was encountered

[cherryjm]

Hi! Thank you for your work! I met a cuda error:

CUDA kernel failed : an illegal memory access was encountered

void group_points_kernel_wrapper(int, int, int, int, int, const float*, const int*, float*) at L:43 in _ext_src/src/group_points_gpu.cu

It happens randomly. I have tried many solutions on google, but the error still exists. I don't what's wrong. Do you have any ideas about this problem?

Sorry for my delay reply and thanks for your interest in our work.
The problem may be that the GPU memory is not enough. Can you reduce the batch size and try again?

Hi @zeliu98 ! I set the batch size to 1, but the problem still exists.

Hi @cherry-ing. That's weird, can you tell me your environment like python, CUDA and pytorch version?
