Predicy.py non working

[DanieleBertagnoli]

Hi, I was trying to execute the test on YCB Video following you instruction. While I was building the dockerfile I faced the problem mentioned in an older issue with pyglet and pyrender versions that were generating a conflict. I tried to skip pyglet installation, however the pyrender version installed (0.1.45) has installed also pyglet 2.0.10 as dependency. When I try to execute predict.py an exception is thrown saying that pyglet 2.0.10 requires Python 3.8 or newer.
