@chasingw Sorry, i did not get how to solve this issue. Could you please be more clear ?

Thank you.

@traveller59 I also encountered the same issue. I checked the branch whose commit id=a6ae896, then it was found to be the branch of spconv.1.1. How can I use VoxelGeneratorV2 in spcon.2.x ? Now I'm using PyPI version of spconv. Should I do git clone ~~/spconv and add it to pip manually ?

Thank you.

I occasionally find it is enough to just copy&paste the older "VoxelGenerator" into the newer code, since VoxelGenerator is just an independent class.

You are right. I successfully pasted the previous versions of the "VoxelGenerator" and "VoxelGeneratorV2" classes into the new version. thank you
