Searing Spotlights Environment Does Not Work On macOS

[WilliamYue37]

Problem Description

The lights never seem to dim for the Searing Spotlights environment, causing the spotlights to be unnoticeable. Messing around with the "Light Parameters" such as "light_dim_off_duration" and "light_threshold" seem to have no effect.

Video Clip

Here is a link to a video clip showing a random policy running in the Searing Spotlights environment. The environment in the video was rendered with "rgb_array" as the render mode. The "debug_rgb_array" render mode outputs the same thing. Google Drive Link (takes a while to load)

To Reproduce

Running on an M2 Macbook Air with macOS Sonoma 14.0. Commands to run:

conda create -n memory-gym python=3.11 --yes
conda activate memory-gym
git clone https://github.com/MarcoMeter/drl-memory-gym.git
cd drl-memory-gym
pip install -e .
python memory_gym/searing_spotlights.py

The repository was cloned with commit 7900c0d046680fbaee1712c98daa88a2ad3be3f8. I have also verified that I am running with PyGame 2.4.0 and Gymnasium 0.29.0.

>>> import pygame
pygame 2.4.0 (SDL 2.26.4, Python 3.11.5)
Hello from the pygame community. https://www.pygame.org/contribute.html
>>> pygame.version.ver
'2.4.0'

>>> import gymnasium
>>> gymnasium.__version__
'0.29.0'

Hi @WilliamYue37

thanks for bringing this to our attention.

Unfortunately, I don't have a Mac system available. So I was not able to reproduce your issue by following your steps. At least I can verify that this issue is not apparent when running on Colab.

I will try to get a hold of a Mac to reproduce your issue. In the meantime, could you try pygame 2.5.2 and 2.1.3? I suspect that this might be a pygame issue.

@MarcoMeter Appreciate the prompt response and quick turnaround!

I tried running Searing Spotlights on a machine operating Ubuntu 20.04.1, and it worked without any issues. It appears that the problem is specific to macOS (I've updated the title to reflect this). I attempted to run Searing Spotlights on macOS with both pygame 2.5.2 and 2.1.3, but neither resolved the issue—the lights still do not dim. Fortunately, this is not a critical or blocking problem for me, as I can continue working on the Ubuntu machine. Thanks again for your help.

I'm still waiting for access to a mac.

Can you try using pygame-ce (based on this conversation)?

pip uninstall pygame
pip install pygame-ce --upgrade

[WilliamYue37]

Swapping out pygame for pygame-ce did not seem to do anything. I verified that I was running pygame-ce

>>> import pygame
pygame-ce 2.3.2 (SDL 2.26.5, Python 3.11.5)
>>> pygame.version.ver
'2.3.2'

I was able to reproduce this issue on a macbook as well. I will try to find a fix soon.
