Set q for exiting the program. Move cv2.waitKey() outside the for loop that detects face landmarks.
Using the keyboard module in linux requires root permission and if virtual envs are used to run the script, it will produce the following error: ImportError(You must be root to use this library on linux.) To solve this, use OpenCV waitKey() functionality.

In the blink detection script, there were 2 problems.
The first problem was quitting the script. Since the cv2.waitKey() was inside the for loop that processes the facial landmarks, we can not quit the script. It should be moved outside the for loop. I assigned "q" for exiting the script.
The second problem was the keyboard module. Using keyboard module in Linux causes the following error: "ImportError: You must be root to use this library on linux."
I replaced kb.is_pressed('space') with cv2.waitKey(1) == 32
