error: OpenCV(4.5.2) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-kuwfz3h3\opencv\modules\core\src\arithm.cpp:214: error: (-209:Sizes of input arguments do not match) The operation is neither 'array op array' (where arrays have the same size and type), nor 'array op scalar', nor 'scalar op array' in function 'cv::binary_op'
错误原因：
1、img和img2的数据类型不一致，img为uint8，img2为float32，所以提示数据类型不一致：where arrays have the same size and type
解决方法：
1、修改img和img2为同样的数据类型：
#VX公众号:桔子code / juzicode.com
import cv2
import numpy as np
print('cv2.__version__:',cv2.__version__)
img = np.arange(0,50,1,dtype=np.uint8).reshape(5,10)
img2 = np.arange(50,100,1,dtype=np.uint8).reshape(5,10)
print(img.shape)
print(img2.shape)
img_ret = cv2.bitwise_and(img,img2)
print(img_ret)
cv2.destroyAllWindows()==========运行结果：
cv2.__version__: 4.5.2
