Lambda packager 3.8 pukes when packaging cv2. 3.6 handles it fine.

Error:
libGL.so.1: cannot open shared object file: No such file or directory

I think these packages need to be added:
ffmpeg libsm6 libxext6

At jjf opencv was a nightmare but try opencv-contrib-python-headless. This will install opencv such that it can run on CPU only and removes the GUI element which wouldn't work on lambda.
