Skipping the post-processing step due to the error above. You can still use SAM 2 and it's OK to ignore the error above, although some post-processing functionality may be limited (which doesn't affect the results in most cases; see https://github.com/facebookresearch/sam2/blob/main/INSTALL.md). pred_masks_gpu = fill_holes_in_mask_scores( propagate in video: 100%|██████████████████████████████████████████████████████▉| 8113/8114 [06:23<00:00, 21.15it/s] Traceback (most recent call last): File "/data3/ZS/samurai/scripts/demo.py", line 120, in main(args) File "/data3/ZS/samurai/scripts/demo.py", line 93, in main img = loaded_frames[frame_idx] IndexError: list index out of range

Look like a mismatch between the number of frames and the actual number of images in the given folder. Can you check if you have the correct naming of these images?

x, y, w, h = map(float, line.split(','))
ValueError: could not convert string to float: '236 141 400 350'

Please refer to our README, the bbox should be 236,141,400,350

Note: The .txt file contains a single line with the bounding box of the first frame in x,y,w,h format.

The list out of index may happen if the images are not in jpg format.
