RuntimeWarning: invalid value encountered in divide
  gaze = (((gaze-gaze.min())/(gaze.max()-gaze.min())) * 255).astype(np.uint8)
RuntimeWarning: invalid value encountered in cast
  gaze = (((gaze-gaze.min())/(gaze.max()-gaze.min())) * 255).astype(np.uint8)

can we update code with this ?

def getPatchGaze(self, gaze: NDArray[Any]) -> NDArray[Any]:
    g = np.zeros((56,56), dtype=np.float32)
    for i in range(56):

            x2 = 4*i+7
            y1 = 4*j-7
            y2 = 4*j+7
            if x1 < 0:
                x1 = 0
            if y1 < 0:

            if x2 > 223:
                x2 = 223
            if y2 > 223:
                y2 = 223
            g[i,j] = gaze[x1:x2, y1:y2].sum()
    
    # Check if the range of g is suitable for normalization
    if g.max() - g.min()!= 0:
        g = (g - g.min()) / (g.max() - g.min())
    else:
        # Handle the case where all values are the same
        g = np.full_like(g, 127.5)  # Set to middle value of uint8 range
    
    # Cast to uint8, handling NaN values by setting them to 0
    g = np.nan_to_num(g).astype(np.uint8)
    
    return g
