ValueError: Expected x_max for bbox to be in the range [0.0, 1.0], got 1.0025.

🐛 Bug

I tried to transform images using RandomResizedCrop with its bounding box (yolo format). But, there are images that when the program tried to transform the bounding box, I got error saying that the bounding box value (after transformation) is not in the range of 0-1. I already checked the original bounding box, and there is nothing wrong with the original bounding box value.

This is my pipeline

transform = A.Compose([
    A.RandomResizedCrop(608, 608),
], bbox_params = A.BboxParams(format='yolo'))

This is the code to place the bounding box to an array and transform it

    bboxes = []
    for dt in data:
        ann = []

        # Split string to float
        c, x, y, w, h = map(float, dt.split(' '))
        ann.append(x)
        ann.append(y)
        ann.append(w)
        ann.append(h)
        ann.append(c)

        bboxes.append(ann)

    transformed = transform(image=img, bboxes=bboxes)

And this is the error
