Questions about the results of bevformer in table1. #25

Open LHY-HongyangLi opened 1 year ago

LHY-HongyangLi commented 1 year ago

Hi, Dr.Harley, simple-bev is really a nice work, however, when running the code to reproduce the results in “table1” I meet some problems:

  1. Is "simple_bev/nets/bevformernet.py” corresponds to the "Deformable attention” in “table1” and "simple_bev/nets/bevformernet2.py” corresponds to the "Multi-scale deform. attn.” in “table1”?
  2. The performance of “bevformernet.py” seems to be similar with “segnet”(as shown bellow). I don’t know if I have did anything wrong.
  3. When training the "bevformernet2" it tends to be overfitted, IOU_v is low. Thank you for your attention, I would be really grateful if you can help me out.

I think the bevformers in this repo still needs to be cleaned up -- for sure bevformer2.py is broken right now. I think the first bevformer should outperform segnet on average, so it's possible something is wrong. Did you already figure out that you need to compile the nets/ops/ ?

ptr-br commented 1 year ago

Hey,

how exactly does the compilation of the nets/ops work?

Thanks!

aharley commented 1 year ago

Go to ./nets/ops and run sh make.sh

@aharley How can I reproduce "Multi-scale deform. attn.” in “table1” IoU？

pianogGG commented 11 months ago

@LHY-HongyangLi Have you reproduced the Multi-scale deform. attn. 48.9 this？

@aharley @LHY-HongyangLi When I run bevformer:

python train_nuscenes.py \

   --exp_name="bevformer" \
   --max_iters=25000 \
   --log_freq=1000 \
   --dset='trainval' \
   --batch_size=8 \
   --grad_acc=5 \
   --use_scheduler=True \
   --data_dir='/data/nuscenes' \
   --log_dir='logs_nuscenes' \
   --ckpt_dir='checkpoints' \
   --res_scale=2 \
   --ncams=6 \
  --encoder_type='res101' \
   --do_rgbcompress=True \
   --device_ids=[0,1,2,3,4,5,6,7]

and the log: Screen Shot 2023-07-27 at 17 17 45 this is very strange, any good advices? Thanks a lot.

can you run the code directly? Segnet is used in the train_nuscenes.py, I changed it as "from nets.bevformernet2 import Bevformernet" and I also changed the model in train_nuscenes.py.

However, I show me an error when it goes bevformernet2.py#L497 .

Could you please share how you run or modify the codes?

Best regards and thank you very much！
