Bug with tools/test.py, when no 3dbox, the program can't run.

Hi, I just found that when I run tools/test.py with your pretrained model as follow command:
python tools/test.py /wangyh12/mmdetection3D/configs/fcos3d/fcos3d_r101_caffe_fpn_gn-head_dcn_2x8_1x_nus-mono3d.py /wangyh12/mmdetection3D/checkpoints/fcos3d_r101_caffe_fpn_gn-head_dcn_2x8_1x_nus-mono3d_20210715_235813-4bed5239.pth --eval mAP --show --show-dir/wangyh12/mmdetSave
It turns out that with pic '../nuScenes/samples/CAM_BACK_RIGHT/n015-2018-08-02-17-16-37+0800__CAM_BACK_RIGHT__1533201470427893.jpg', the model can't predict a 3dbox, which with your code in mmdet3d/core/bbox/structures/cam_box3d.py. There is a command in 129 lines, to assert that there must be at least one 3dbox. I'm afraid that this should be a bug, plz help to fix that problem. Thx

Sorry for the late reply, could you please offer the error log so that we could fix it ASAP?

After rechecking the code, the assertion problem in 129 lines have been modified in v1.0.0.dev0 branch, we will fix the bug in master branch in the future.
