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.
