TTA error when batch_size is set more than 1?

[fengdian8564]

Setting batch_size to 2 when running "test.py"（config file is tools/cfgs/det_model_cfgs/centerpoint_1sweep.yaml）.There is an error in 16th line of "detzero_det/utils/ensemble_utils/wbf_3d.py".

The reson of the error is that shapes of boxes、scores and labels are not matched.
（boxes [bs，ops_ num，max_proposals_num，dims_num]、scores [bsops_num, max_proposals_num, 1]、labels [bsops_num, max_proposals_num, 1]）

What`s more, I found 206th line of "detzero_det/models/centerpoint.py" is not worked because the first dim of boxes is not 1 when batch_size settings is more than 1. I'm not sure if the original idea for 206th line was to use "reshape" or "view".
However, if I changed 206th line with "reshape" or "view", there will be another issue that TTA will perform WBF on all proposals in batch.

I`m not sure whether my thoughts are right. Maybe there are some other thoughts about that.
Thank you for your time and consideration. I look forward to your response at your convenience.
