There is no cv2 package that you can install. You probably want opencv-python-headless or opencv-contrib-python-headless .

Hi @xxy0717 
As Goyo pointed out earlier, you need to add opencv-python-headless to your requirements.txt file, as you’ve done for numpy, Pillow, etc. Once you do so, you should no longer run into the error:
