[BUG] cooperative_groups/scan.h not in cuda11.X

[MichoChan]

how to fix it?

[MichoChan]

use cub ？

Hi @MichoChan , can you elaborate the CUDA version at which the header file is missing? If you use NGC container, e.g., nvcr.io/nvidia/pytorch:22.12-py3 with CUDA 11.8, there is no such problem:

cuda 11.2 in my env

Hi @MichoChan , if you have to use cuda 11.2, it is good for you to leverage cub or thrust.

/usr/local/cuda/include# find -name "*scan*h"
./thrust/scan.h
...
./cub/agent/agent_scan.cuh
...
