"""
Calculate the Intersection over Union (IoU) between pairs of bounding boxes.
Args:
box1 (np.array): A numpy array of shape (n, 4) representing 'n' bounding boxes.
Each row is in the format (x1, y1, x2, y2).
box2 (np.array): A numpy array of shape (m, 4) representing 'm' bounding boxes.
Each row is in the format (x1, y1, x2, y2).
eps (float, optional): A small constant to prevent division by zero. Defaults to 1e-7.
Returns:
(np.array): A numpy array of shape (n, m) representing the IoU scores for each pair
of bounding boxes from box1 and box2.
Note:
The bounding box coordinates are expected to be in the format (x1, y1, x2, y2).
