Reduce the learning rate?
Where to find learning rate in code? Any links
@xmyqsh Kindly help. @poodarchu
made div_factor=100,10000 from 10.0. Still nan Values . Plesae hekp @xmyqsh , @poodarchu
Please install nuscene-devkit following the installation and create data again. Official nuscenes-devkit will lead to this phenomenon.
So is this a bug in the offical nuscenes-devkit or you just revise some code for your dataset? @a157801
refer this https://github.com/poodarchu/Det3D/issues/19
@a157801 It is better to give a benchmark of group class balancing on KITTI or a subset of nuScene. Most of us are CPU urging.

It is not a bug, we add velocity as an element of box when applying get_boxes function.
refer this #19 Please install the nuscenes-devkit following install.md

Group class balancing aims to overcome the imbalance among a large number of categories, so it does not work on KITTI.
Kindly help all values are naN . Iam using single GPU
