我运行了以下代码，但出现错误

OpenCV（3.4.1）C：\ projects \ opencv-python \ opencv \ modules \ imgproc \ src \ thresh.cpp：1406：错误：（-215）src.type（）==（（（（0）＆（（ 1 << 3）-1））+（（（（1）-1）<< 3））在函数cv :: threshold中

我不清楚这意味着什么以及如何解决它

import numpy as numpy
from matplotlib import pyplot as matplot
import pandas as pandas
import math
from sklearn import preprocessing
from sklearn import svm
import cv2

blur = cv2.GaussianBlur(img,(5,5),0)
ret3,th3 = cv2.threshold(blur,0,255,cv2.THRESH_BINARY+cv2.THRESH_OTSU)
image = numpy.invert(th3)
matplot.imshow(image,'gray')
matplot.show()
