SpaceInvaders(SAC_Discrete) : Error

[FarhaParveen919]

Dear Petros,

Thank you very much for the implementations and it is very useful. I was able to successfully execute the code in the file Cart_Pole.py. I am now am trying to run the Space_Invaders.py file with SAC_Discrete, but had received the following error.

AttributeError: 'LazyFrames' object has no attribute 'size'.

This same error persists for other games in Atari environment(Road_Runner,Pong etc.) as well as for other methods (SAC_Discrete, DDQN, DQN etc). I have also installed Atari_py of version : 0.2.6.

It would be very helpful if you could provide your suggestions/insights on the error and methods to fix it. I have attached the python file and a snapshot of the error with this request.

Thanks,
Farha Parveen

Excuse me, have you finally solved this problem？

+1 error also for SpaceInvaders + SAC_Discrete.
So this now makes things harder to be verified for the results in the SAC_Discrete arXiv preprint paper.

Any help greatly appreciated! :)
