ValueError: Could not load "" Reason: "image file is truncated"

Hello, I am in trouble when I run the 5_evaluation_bop_basic.py file. The error is:

I downloaded the T-LESS dataset from the BOP, which lacks images 08-109.png, 08-110.png, 09-244.png, 14-367.png, 18-497.png. I downloaded the corresponding file from the official website, and it is still error in the position of 09-244.png after being placed.

Can you tell me how to solve it?

Hello, I solved this problem, add the following code：

from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True

Thank you very much for your help. Although I still haven’t solved the problem after using the pictures you provided. When I try to load images with other image libraries, the error is:

Recognizing scene_id:9, im_id:242
Recognizing scene_id:9, im_id:243
libpng error: Read Error
Traceback (most recent call last):
  File "/home/Pix2Pose/tools/5_evaluation_bop_basic.py", line 261, in <module>
    image_t = cv2.imread(rgb_path)[:, :, ::-1]
TypeError: 'NoneType' object is not subscriptable

I am very sorry to trouble you for so long. I will find the reason myself. Best wish.
