How to convert "InMemoryUploadedFile" image to OpenCV?

Question

Python

image = form.cleaned_data.get('image')
gray = cv2.cvtColor(image.read(), cv2.COLOR_BGR2GRAY)

It returns the error "src is not a numpy array, neither a scalar", how to convert it correctly?

Answer 1

May be

image = cv2.imread("filename")
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

And if not from a file, thencv2.imdecode
