UnpicklingError: invalid load key, '\xef'.

[sebastianfernandezgarcia]

3 days ago my code was working cloning the repo and using:

from detectron2.config import CfgNode as CN
from detectron2.config import get_cfg
from detectron2.utils.visualizer import ColorMode, Visualizer
from detectron2.data import MetadataCatalog
from detectron2.engine import DefaultPredictor

cfg = get_cfg()
add_vit_config(cfg)
cfg.merge_from_file("cascade_dit_base.yml")
cfg.MODEL.WEIGHTS = "publaynet_dit-b_cascade.pth"

predictor = DefaultPredictor(cfg)

After the last commit in the repo, gives me this error:

---------------------------------------------------------------------------

The error is beacause there is a missing file when downloading some utils.

This file:
