I am just trying to read image through cv2 in my code and I am facing following error.

cv2.error: OpenCV(4.5.2) C:\Users\ssc\AppData\Local\Temp\pip-req-build-vi271kac\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

How To Solve cv2.error: OpenCV(4.5.2) color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function ‘cv::cvtColor’ Error ?

Solution 1: Check Image path

Please check image path. This error usually occurs when image is not loaded correctly in any way.

Here is how this error occurs.

import cv2
im = cv2.imread("WRONG IMAGE ADDRESS.jpg", 1)
im = cv2.cvtColor(im, cv2.COLOR_RGB2GRAY)

// Now we will face this error.
cv2.error: OpenCV(4.5.2) C:\Users\ssc\AppData\Local\Temp\pip-req-build-vi271kac\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

Try to giving the image address directly; something like

im = cv2.imread("D:\\your_image.jpg", 1)

Solution 2: wrong image location

You might given wrong image location. Or esle try to assign diffrent path.

im = cv2.imread("../images/car.jpg",1)

Solution 3: Give Full Path

I just give full path and that was worked for me.

im = cv2.imread("D:\My_Image\CANON80D\dang\fvrt.jpg",1)
