ImportError: cannot import name 'VoxelGenerator' from 'spconv.utils #34

Closed Soodep closed 1 year ago

Soodep commented 1 year ago

python -m pcdet.datasets.kitti.painted_kitti_dataset create_kitti_infos tools/cfgs/dataset_configs/painted_kitti_dataset.yaml gives me the following error:

in transform_points_to_voxels from spconv.utils import VoxelGenerator ImportError: cannot import name 'VoxelGenerator' from 'spconv.utils' (/home/UNT/sd0570/anaconda3/envs/pointpainting/lib/python3.8/site-packages/spconv/utils/init.py)

I am getting this import error. Is it because of the mismatch in spconv version? I just wanted to know which version of spconv you are using because openpcdet has special requirements. Could you please specify the version of following:

  1. CUDA
  2. Pytorch
  3. spconv
  4. cudatoolkit

This was because I was using spconv2.x, but for this project we have to strictly use spconv1.2.1. Once i installed the spconv1.2.1, this problem was solved.
