Generated images without movable objects

Hi, great work for your job!
Why are there no foreground objects such as cars in the pictures I generated?
By the way,I have no openai account so i can't generate updated_description_.pkl file, so i just use original 12Hz_.pkl as WorldDreamer's input, is that the reason?

The visualization you show and the box projection at inference time are not executed at the same time. It is possible that the visualization is correct but the box is not actually projected onto the canvas.
Maybe you can check the code in the following function to see if it is executed correctly.

DriveArena/WorldDreamer/dataset/map_utils.py

Line 121 in ba7dd86

def project_box_to_image(gt_bboxes_3d, gt_labels_3d, transform, object_classes, image=None, cam_name=None):

@jokester-zzz thank you very much! I have solved this problem. Due to mismatched opencv version, cv2.line may raise an tuple error, so by try: except: judgment, it may skip draw lines!

Congratulations on solving the problem! And it reminds me to add some instructions there😆
