Can you share the picture?

Hi there, I am also getting this issue. I also tried not defining the input_box, and it instead gives 'NoneType' object is not subscriptable (the default value is "none" but there is no check for this).

Similarly, when using the manualmaskpredictor for video with the example provided in the readme, it errors because input_box is None

Change this line to: coords = np.array(deepcopy(coords), dtype=np.float32)

That resolved my issue :)
