CARLA : Simulateur pour la navigation autonome d'un véhicule

Bonjour,
Je suis sur un projet CARLA, et j'essaie d'executer un scripte sous Python, mais il me retourne une erreur au niveau de la ligne 33 qui dit que le pygame n'est pas installer or que je l'ai bien installer, voici le scripe que j'essaie d'executer :

J'espère que j'ai été claire.
