Hi,

You mentioned before that the point poillar implementation in this repo is an unofficial implementation. Could you point out what are the main differences or deviations?

PointPillars have a SSD Head while this repo replace it with 1 layer 1x1 conv. This modification is proposed by @nutonomy.

Any posts that I can refer to regarding this?
