Package has a version of pygame as dependency which does not support rendering

I got this issue on Linux. The package has pygame>=2.0.0 as a dependency:

Line 58 in 4b6c19c

"pygame>=2.0.0",

but according to google-deepmind/pysc2#308 (comment), games can only be rendered using pygame up until version 1.9.6.

Hi. Are you using the same conda environment for both SMAC and PySC2? SMAC's environment rendering code is completely decoupled from that of PySC2 (it's a completely different piece of code). So if you're not using PySC2's rendering with SMAC (which isn't used anywhere in SMAC), you could just have pygame>2.0.0 in smac conda environment? The thing is that pygame>2.0.0 is much faster compared to previous versions.

The specific problem I had was that I was unable to watch replays, as taught in the SMAC README (https://github.com/oxwhirl/smac#watching-a-replay) right after installing SMAC. I had to downgrade pygame first. So, that specific step in the README does not work out of the box, given SMAC's installation requirements.

Is pygame necessary for running SMAC at training time? If it is, then I understand using a faster version of it. Otherwise, it seems like having pygame<=1.9.6 as a dependency is a safer bet, as it allows users to watch games and replays. Unless this is a platform-specific problem and others aren't facing it.

I saw that #71 is a great PR but it depends on pygame 2. So I guess the "Watching a replay" section of the README needs to warn people that watching replays needs pygame 1.9.6, while watching live games (the default) needs 2.0.0?

The python -m pysc2.bin.play --norender --replay <path-to-replay> command works for me (with pygame 2.0.1). Arre you sure you're passing the --norender flag? What does the error say?
