debug: groundingdino/util/inference.py 202 line, no return channel value
source_h, source_w, _ = image.shape # not enough values to unpack (expected 3, got 2)

If forced to change to
source_h, source_w = image.shape[:2]
you will not be able to get the mask later.

In addition to single-channel images such as black and white or grayscale, some color images cannot be detected.
