ValueError: Cannot finished cropping adjustment within 25 tries (#instances 637).

[13181713593]

I made a mistake in training, the following is the error message.

the source code in "adet/data/augmentation.py", line 53:

# if some instance is cropped extend the box
if not crop_box:
        num_modifications = 0
        modified = True

	#convert crop_size to float

    crop_size = crop_size.astype(np.float32)
    while modified:
        modified, x0, y0, crop_size = adjust_crop(x0, y0, crop_size, instances)
        num_modifications += 1
        if num_modifications > 25:
            raise ValueError(
                "Cannot finished cropping adjustment within 25 tries (#instances {}).".format(

            )
            return T.CropTransform(0, 0, image_size[1], image_size[0])

return T.CropTransform(*map(int, (x0, y0, crop_size[1], crop_size[0])))

I don't know why such a requirement num_modifications > 25, and how to settle this problem
