import cv2

def resize(fp: str, scale: Union[float, int]) -> np.ndarray:
    """ Resize an image maintaining its proportions

    Args:
        fp (str): Path argument to image file
        scale (Union[float, int]): Percent as whole number of original image. eg. 53

    Returns:
        image (np.ndarray): Scaled image
    """    
    _scale = lambda dim, s: int(dim * s / 100)
    im: np.ndarray = cv2.imread(fp)
    height, width, channels = im.shape
    new_width: int = _scale(width, scale)
    new_height: int = _scale(height, scale)
    new_dim: tuple = (new_width, new_height)
    return cv2.resize(src=im, dsize=new_dim, interpolation=cv2.INTER_LINEAR)

#18 should be:
new_dim: tuple = (new_height, new_width)

@rkosti Thank you for looking at the code!
It does appear the dsize in OpenCV is (width, height).

The dsize in OpenCV is correct.
Your interpretation of the cv2.imread is not. I wrongly pointed to the incorrect part last time. I think it's #15 that needs change.
#15 height, width, channels = im.shape
I hope this helps :)

@rkosti Thanks for your help fixing the code. Good eagle eyes spotting the transposition.

You're welcome. I realized that my screenshot didn't upload last time. I updated the comment.
Happy Coding :)
