When I run

./tools/dist_test.sh ./configs/bevdet_occ/bevdet-occ-r50-4dlongterm-stereo-24e_384704.py ./bevdet-occ-r50-4dlongterm-stereo_384704-24e.pth 7 --eval miou

got

RuntimeError: shape '[1, 1, 3, 3]' is invalid for input of size 16

bda = bda.view(B, 1, 4, 4).repeat(1, N, 1, 1)

I got the same results as you reported.
