Additional information

hi, i have successfully run the mono_det_demo.py with fcos3d (though results not quick accuracy):

export cam_pkl=demo/data/kitti/000008.pkl
export img_uri=demo/data/kitti/000008.png
export mdl_cfg=configs/fcos3d/fcos3d_r101-caffe-dcn_fpn_head-gn_8xb2-1x_nus-mono3d_finetune.py
export mdl_ckp=ckpts/fcos3d_r101_caffe_fpn_gn-head_dcn_2x8_1x_nus-mono3d_finetune_20210717_095645-8d806dc2.pth # checkpoint file wget in advance
export cam_idx=CAM2
export out_dir=my_test/f3d_ki.png

python demo/mono_det_demo.py ${img_uri} ${cam_pkl} ${mdl_cfg} ${mdl_ckp} --cam-type ${cam_idx} --out-dir ${out_dir}

i wish to test the detr3d as well:

export cam_pkl=demo/data/kitti/000008.pkl
export img_uri=demo/data/kitti/000008.png
export mdl_cfg=projects/DETR3D/configs/detr3d_r101_gridmask.py
export mdl_ckp=ckpts/detr3d_r101_gridmask.pth
export cam_idx=CAM2
export out_dir=my_test/detr3d_ki.png

python demo/mono_det_demo.py ${img_uri} ${cam_pkl} ${mdl_cfg} ${mdl_ckp} --cam-type ${cam_idx} --out-dir ${out_dir}

which errors like:

i am new to open-mmlab and mmdet3d, though investigated the code/config, still cannot find any clue, could i have some advice? thanks
