OpenPCDet, spconv version issue #3

Closed Minwookk closed 2 years ago

Minwookk commented 2 years ago

In instruction, you recommended spconv 2.x version . but, given checkpoint trained pcdet version ==0.3.0. Which one is correct?

yukang2017 commented 2 years ago

Hi, spconv 2.x is correct. We can also use spconv 2.x in pcdet==0.3.0 version.

Minwookk commented 2 years ago

In OpenPCDet official github, pcdet version ==0.3.0 should be matched to spconv 1.x version. do you ignore it? and your github provides pcdet version 0.5.2, isn't it?

yukang2017 commented 2 years ago

There is not so much difference in usage between spconv 2.x and spconv 1.x. Because spconv 2.x is easy to install, I change the version of spconv to 2.x in pcdet==0.3.0 when preparing the checkpoints, following this doc.

Thank you for you answer! but your github provides pcdet==0.5.2, is right?

Yes. I have also merged it into the newest OpenPCdet official version.
