cv2.error: OpenCV(4.1.1) C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'


cv2.error:'cv::cvtColor'


原因：OpenCV无法读取中文路径的图片  返回为None


一定要读取中文路径的图片，则：
pip3 install scikit-image
import skimage.io as iio
img = iio.imread('图片路径')
读取之后一样是BGR的
再用OpenCV转换颜色空间
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)



# 下面这个也可以读中文路径
from PIL import Image as pil_image
img = pil_image.open(path, mode='r')
print('original size:', img.size)
img = img.resize(target_size, pil_image.NEAREST)
