Contribution

I fix a problem with wrong cur_geom_feats address in file of bev_pool_cuda.cu.

Problem

The result is different between the output of function QuickCumsumCuda and the output of function QuickCumsum in file bev_pool.py and another repo.

the reason is the wrong implement of file bev_pool_cuda.cu and another repo

Reproduce

To reproduce the wrong different result, you can follow the instruction of file README.md https://github.com/ZouJiu1/bevPool/blob/master/README.md

step 1

reproduce the problem

download the file bev_pool_cuda.cu

mv bev_pool/src/bev_pool_cuda.cu bev_pool/src/bev_pool_cuda_tmp.cu

git clone https://github.com/ZouJiu1/bevPool.git

cd bevPool

pip install -e .

cd bev_pool

python3 bev_pool.py

by checking or debuging or printing the variables like error, errorMean, www, tmp, tmp2 in file bev_pool.py, you can reproduce the problem

step 2

fix the problem

mv bev_pool/src/bev_pool_cuda_tmp.cu bev_pool/src/bev_pool_cuda.cu

cd bevPool

pip install -e .

cd bev_pool

python3 bev_pool.py

by checking variables in file bev_pool.py, you will find the problem is fixed.
