BEVDepth perform very bad when training with batch size 1!

Hi! I'm currently training the bevdepth models with different batch size.
I used 1,2,4,8 GPUs with batch size=1, 2, 4.
All the models trained with batch size=1 seems to perform bad on nuScenes val set (0~3mAP).
All the models trained with batch size != 1 perform reasonable (20~30mAP).
can you give me some advices about how to change the config to make it work when batch size=1?

When batch size=1, what is your GPU memory usage？

the GPU memory is about 6G when batch size is 1, the experiment config is bev_depth_lss_r50_256x704_128x128_24e.py modified from bev_depth_lss_r50_256x704_128x128_24e_ema.py
