我正在使用下面的 scipy signaltonoise 函数是代码，但它返回一个错误。我也在github中搜索过这个，但找不到。你能帮忙吗。

import numpy as np
import cv2
import math
import os
import csv
from scipy import stats 
from PIL import Image
from skimage.color import rgb2gray
from multiprocessing import Pool
from skimage.feature import local_binary_pattern # Local Binary Pattern function
from scipy.stats import itemfreq # To calculate a normalized histogram
import scipy.stats as sp
from skimage.feature import hog
from scipy.ndimage.measurements import label
from scipy import signal as sg




def calc_snr(img):
    snr = stats.signaltonoise(img, axis=None)
    return snr


 snr = calc_snr(img)
