run error about the Nuscenes dataset.

[rockywind]

Thank you for your help on the previous issue. I run the test script( test.py) in the Nuscenes data, the error is below. But, it's normal when I run the test script in the kitti dataset. `root@39370106c70e:/workspace/imvoxel# sh eval.sh [ ] 0/6019, elapsed: 0s, ETA:ERROR: Unexpected bus error encountered in worker. This might be caused by insufficient shared memory (shm).

The above exception was the direct cause of the following exception:

Hi @rockywind ,

Most likely this bug is unrelated to imvoxelnet and for sure can be googled as a pytorch issue. Are you using docker? Try increasinr your shared memory by --default-shm-size="16gb".

Thank you for your help on the previous issue. Yes, I am using docker. It works for me. sudo docker run --shm-size=16G -v /newnfs/zzwu/08_3d_code/imvoxelnet05/:/workspace/imvoxel -it imvoxelnet_save
