Erreur: n'a pas pu trouver de version qui satisfait l'exigence CV2 (à partir des versions: Aucune) Erreur: aucune distribution correspondante trouvée pour CV2
#Know the reason is really dumb, because the reason is that the package of CV2 is not called cv2 but called opencv-python
pip install opencv-python
#For python3:
pip3 install opencv-python
