Concern on using VMamba backbone

[BaophanN]

Dear author, thanks for this amazing work. I am also interested in using VMamba as backbone for my project. My baseline uses mmcv 1.5.2 and mmdet3d1.0.0rc, which is very old to use new CUDA version for Mamba-based model. How did you manage to integrate Mamba backbone into your model. Thank you.
