When show_box = false in test_config.yaml There is a problem with the loop iteration over gen_imgs_wb_list. This loop does not execute because there are no elements in gen_imgs_wb_list.

for map_img, ori_imgs, ori_imgs_wb, gen_imgs_list, gen_imgs_wb_list in zip(*return_tuples):

I deleted gen_imgs_wb_list in that line and commented code related to show_box=true, and the script("demo/run.py") can run correctly. So I think there is no problem with enviroment. I'm using the nuscenes v1.0 mini dataset, and I suspect this happened cuz not reading the files related to the 3D BOX labels in the groundtruth data.

Yes, it seems there are some bugs here. However, it does not affect the major functionality, and I do not have time to fix them.

PR is welcome. Thanks.

I have solved the issue when show_box=false. However, it is unclear what causes the first case in your issue. Please provide more context like the command version of bevfusion.

I will close it for now. If you have any follow-ups, please feel free to re-open.
