Module not found and preload error

[ameliazhengg]

Hi, I am trying to use pygbag to run this pygame: https://github.com/portal-cornell/robotouille/tree/main. However, I cannot get past a black screen. I have imported all dependencies necessary and believe I have main.py set up correctly:

# /// script
# dependencies = [
#  "numpy",
#  "matplotlib",
#  "pandas",
#  "scipy", 
#  "pillow",
#  "cycler",
#  "kiwisolver", 
#  "dateutil",
#  "six", 
#  "gym",
# ]
# ///

from robotouille import simulator
import argparse
import asyncio

async def main():
  while True:
    parser = argparse.ArgumentParser()
    parser.add_argument("--environment_name", help="The name of the environment to create.", default="original")
    parser.add_argument("--seed", help="The seed to use for the environment.", default=None)
    parser.add_argument("--noisy_randomization", action="store_true", help="Whether to use 'noisy randomization' for procedural generation")
    args = parser.parse_args()

    simulator(args.environment_name, args.seed, args.noisy_randomization)
    await asyncio.sleep(0)

asyncio.run(main())

When running in debug mode, I see two main errors:

1. No module named ‘gym’: I have installed ‘gym’ in my environment and have also added it to the dependencies list. I’ve also tried running pygbag with the -git flag as suggested for non-standard dependencies, but I still can’t resolve the issue

2. Additionally, I am also seeing a lot of preload errors such as “support/EMSCRIPTEN.c: preload [/data/data/org.python/assets/site-packages/pygame/threads/init.py] ERROR”

Any help debugging these errors would be much appreciated.

you may put a request for "gym" here https://github.com/pygame-web/pkg-porting-wasm/issues as it need to be compiled to Web Assembly.
this https://github.com/portal-cornell/robotouille/blob/main/robotouille/robotouille_simulator.py#L14 is a blocking loop and would not work anyway.

all infinite loops must contain "await asyncio.sleep(0)" and be in "async def" functions and must be "await"-ed from caller
