i donĀ“t understand this syntax error when using OpenCV

Category Image 101

This is the error message:

%Run -c $EDITOR_CONTENT
Traceback (most recent call last):
File "<string>", line 6
image = cv2.imread(C:\Users\Audun Nilsen\Pictures\pica.webp)
^
SyntaxError: invalid character in identifier

This is the code:

import cv2 # OpenCV for image processing

image = cv2.imread(C:\Users\Audun Nilsen\Pictures\pica.webp)
