[jyothsna-phd22]

Hi,

While I was training any model on kitti dataset, I am getting floating point exception at epoch 0 and terminated training. How to resolve this issue??

Kindly help me....

Same here. I am training cfgs/nuscenes_models/cbgs_pp_multihead.yaml on the nuScenes mini dataset. @jyothsna-phd22 : were you able to resolve the issue?

Tracked down the offending call. It's tv.from_numpy(points) on this line: https://github.com/open-mmlab/OpenPCDet/blob/master/pcdet/datasets/processor/data_processor.py#L55.

I don't yet know how to fix it. I was just sharing that it seems to be the offending line.

On digging further, it seems this is due to a mismatch between the binaries of the spconv library and the rest of the environment. I got it to run using the dockerfile in this PR: #1648

This issue is stale because it has been open for 30 days with no activity.

Same issue here，this is my env info：
python 3.10.14
CUDA 12.1
numpy 2.0.1
spconv-cu120 2.3.6
Here is my solution for reference: downgrade numpy version to 1.26.4
conda install numpy=1.26.4
