Opencv-Python学习入门是常犯的错误

使用opencv中的cv2.imread()时候出现了这个错误：
Traceback (most recent call last):
File “E:/PycharmProjects/pythonPic/com/wang/video/makesumiao.py”, line 9, in
cv2.imshow(‘dst_image’, img_rgb)
cv2.error: OpenCV(4.5.3) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-q3d_8t8e\opencv****\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor’****

D:\ProgramData\Anaconda3\envs\pythonPic\python.exe E:/PycharmProjects/pythonPic/com/wang/video/makesumiao.py
None
Traceback (most recent call last):
  File "E:/PycharmProjects/pythonPic/com/wang/video/makesumiao.py", line 9, in <module>
    cv2.imshow('dst_image', img_rgb)
cv2.error: OpenCV(4.5.3) C:\Users\runneradmin\AppData\Local\Temp\pip-req-build-q3d_8t8e\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

出现这个问题的原因是 cv2.imread('路径中有中文字符')

把路径中的中文修改成英文就好了。
