Reproduces the problem - code sample

I was using the original codes for CenterPoint and inference/evaluation

Reproduces the problem - command or script

I just ran the mmdet3d in colab script

config = 'configs/centerpoint/centerpoint_voxel0075_second_secfpn_head-dcn-circlenms_8xb4-cyclic-20e_nus-3d.py'
checkpoint = 'checkpoints/centerpoint_0075voxel_second_secfpn_dcn_circlenms_4x8_cyclic_20e_nus.pth'

!python tools/test.py $config $checkpoint --cfg-options test_dataloader.dataset.metainfo.version='v1.0-mini'

Reproduces the problem - error message

No error information.

Additional information

I ran this script/command twice, but I got two slightly different results. It seems the inference is non-deterministic. Do you have any ideas why?

The TTA RandomFlip3D is causing the issue. Additionally test_mode=True is also required in LoadPointsFromMultiSweeps for it to be deterministic. So for example update your test pipeline to the following:

test_pipeline = [
    dict(
        type='LoadPointsFromFile',
        coord_type='LIDAR',
        load_dim=5,
        use_dim=5,
        backend_args=backend_args),
    dict(
        type='LoadPointsFromMultiSweeps',
        sweeps_num=10,
        test_mode=True,  # make sure this is set to true
        backend_args=backend_args),
    dict(
        type='MultiScaleFlipAug3D',
        img_scale=(1333, 800),
        pts_scale_ratio=1,
        flip=False,
        transforms=[
            dict(
                type='GlobalRotScaleTrans',
                rot_range=[0, 0],
                scale_ratio_range=[1., 1.],
                translation_std=[0, 0, 0]),
            # dict(type='RandomFlip3D'),  # comment out this line
            dict(
                type='PointsRangeFilter', point_cloud_range=point_cloud_range)
        ]),
    dict(type='Pack3DDetInputs', keys=['points'])
