bev_pool_v2怎么比v1慢很多 #356
Comments
@rubbish001 ……这个bevpoolv2加速已经被很多人验证过了,旷视基于这个motivation,也推出了voxelpoolv2,原理上可行性应该是没问题的,我提供的实现也应该是ok的,可以好好查下什么原因导致实现不符合预期的,对个人定制化的内容(修改部分)要好好斟酌 |
我看FB-BEV也是用你的套路,但是他跑50次迭代要4分钟,用的3090,我这里跑第二阶段用的4090,锁住lss的梯度,具有跑50次迭代要1分50秒,以前都是40几秒.不过确实节省显存,点数比以前的那个配置提升了1个点左右。 |
哦哦,谢谢博主哈,我的配置有问题,downsampe =8,速度正常,效果还可以,看看我的效果 |
老板,有没有显卡刷一波多帧融合的,合作搞一篇冲CVPR25 |
您好,有个问题请教一下,FB-BEV的第二阶段是会冻结住一阶段bevdepth那儿的梯度吗? |
FB-BEV的玩法跟我不一样,我是多模态的目标检测,融合阶段的训练会冻住梯度 |
我跑了一下,在
这个配置下,比那个原始的bevFusion慢一倍以上,怎么解决,bev_pool_v2感觉就是节省内存,但是花费的时间直接变长
