Error when Launching Simulator on MacOS Big Sur on M1

[jafny]

Hello,

I am exited to play with this tool and see what it can do! I tried to launch the simulator in verbose mode after installation on my M1 Macbook, and got this error. Could it be a compatability issue?:

hi @jafny -- i'm exited to hear that you're trying to run ambit on mac. i haven't tried this yet and don't have the hardware to test, but happy to try to help out.

it looks like this error originates in pygame somewhere. it might be worth trying to run some simple pygame examples on your M1 and see if those work. could you do that and let me know your experience? as an example: https://github.com/pygame/pygame/blob/main/examples/scaletest.py

it may be that a newer or older version of pygame could also work better. could you include the output of python3 -m pip show pygame to help troubleshoot?

[jafny]

Thanks for the prompt response! Here is the output Name: pygame Version: 2.0.3.dev3 Summary: Python Game Development Home-page: https://www.pygame.org Author: A community project.

I gave it a try on an Ubuntu VM running on ARM it worked straight out of the gate with the newest version, so maybe this is something solely MacOS on ARM specific. My end environment would be ARM Linux anyway so I'm effectively unblocked but happy to help troubleshoot if you are looking to add support.

[khimaros]

i'm still interested in understanding the cause of the failure, but it sounds like it isn't a high priority right now.

would you mind providing the information i requested above for posterity?

Hello, I'm also in the same situation on my mac (not m1 but I have also an m1 to test if you need it)

I install ambit like follow:

$ python3 -m pip install ambit
$ python3 -m pip install pyusb pygame numpy

Then I start the simulator:

ambit_simulator --verbose

result:

[khimaros]

hi @mazerte thank you for the details! could you try installing pygame==1.9.6 and see if that helps? currently, that is what ambit is pinned to in requirements.txt and i haven't tested with more recent versions of pygame (especially 2.x).

[mazerte]

A bit are to test on my mac because pygame 1.9.6 wasn't pre-compiled for python3.9 so I switch to python3.8.

Seems to produce the same result:

Related to that maybe? https://stackoverflow.com/questions/68225235/unable-to-obtain-graphics-context-for-nswindow-mojave-behavior-pygame

[khimaros]

a few ideas to try:

1. i see they solved it by installing a dev version of pygame. have you tried that? pip install pygame==2.0.0.dev6
2. are you able to run any of the pygame examples i linked above,such as https://github.com/pygame/pygame/blob/main/examples/scaletest.py ?
3. there are some instructions here https://www.pygame.org/wiki/GettingStarted#Mac%20installation
4. i see some places suggesting it might help to install the right libraries with homebrew, eg. brew install sdl sdl_image sdl_mixer sdl_ttf portmidi smpeg

thank you for trying to help resolve the issue.

[mazerte]

i see they solved it by installing a dev version of pygame. have you tried that? pip install pygame==2.0.0.dev6

Didn't work better

are you able to run any of the pygame examples i linked above,such as https://github.com/pygame/pygame/blob/main/examples/scaletest.py ?

Yes work fine with 1.9.6, 2.0.0.dev6 and 2.1.2

there are some instructions here https://www.pygame.org/wiki/GettingStarted#Mac%20installation

Yes I follow these but nothing

i see some places suggesting it might help to install the right libraries with homebrew, eg. brew install sdl sdl_image sdl_mixer sdl_ttf portmidi smpeg

Yes library was missing on my first try and I install these to make it compile but it and up with the error above

[mazerte]

I try the example here: https://stackoverflow.com/questions/68225235/unable-to-obtain-graphics-context-for-nswindow-mojave-behavior-pygame

And it works

[mazerte]

From my searches and understanding (I have basic Python knowledge and never play with pygame ...), it seems that your are rending the interface outside the main thread ->

ambit/ambit/render.py

Line 244 in b5f1101

self.thread = threading.Thread(target=self.worker)

I found this issue on deepmind/pysc2 google-deepmind/pysc2#2 that was fixed by this PR google-deepmind/pysc2#17

I hope it helps
