My working ENV

System: ubuntu 18.04

Version: python 3.6/3.7/3.8(3 envvironments all the same result), gym 0.25.2, gym-retro 0.8.0

How did I do?

I follow this guide to install gym-retro. and I successfully run the example game.

Problems I met?

Firstly, I imported some ROMs from the internet, for example the the 128 sine-dot, But I CANNOT import it: when I executed

python -m retro.import Anthrox\ -\ Sine-dot\ Demo\ \(PD\).smc

the result was:

Imported 0 games

picture of text above

and the Atari games (more than 1000 games),I could only successfully import no more than 200 games, but I can make env no more than 100 games.

I executed:

python -m retro.import .

and results was:

Importing DemonAttack-Atari2600
.
.
Importing Pong-Atari2600
Imported 167 games

I wrote this script to get game status to judge whether we can make this env:

import retro

game_list = retro.data.list_games()

def main():
    cnt = 0
    for game_name in game_list:
        try:
            env = retro.make(game=game_name)
        except Exception as e:
            print(game_name, ": ", "no")
        else:
            cnt+=1
            env.close()
            print(game_name, ": ", "yes")
    print("all: ", cnt)

if __name__ == "__main__":
    main()

and the results was:

...
YarsRevenge-Atari2600 :  yes
YoukaiClub-Nes :  no
YoukaiDouchuuki-Nes :  no
YoungIndianaJonesChronicles-Nes :  no
Zanac-Nes :  no
Zaxxon-Atari2600 :  yes
ZeroTheKamikazeSquirrel-Genesis :  no
ZeroTheKamikazeSquirrel-Snes :  no
ZeroWing-Genesis :  no
ZombiesAteMyNeighbors-Snes :  no
ZoolNinjaOfTheNthDimension-Genesis :  no
ZoolNinjaOfTheNthDimension-Sms :  no
ZoolNinjaOfTheNthDimension-Snes :  no
all:  63

UPDATE INFO, all exceptions were:

Game not found: xxxxxxxx. Did you make sure to import the ROM?

and found out that only 63 games were makeable.

Questions I want to ask!!!

How could I import those games to my retro?

• The first sentence from the guide/documentation you linked says: Gym Retro requires one of the supported versions of Python (3.5, 3.6, or 3.7) - and I see you use Python 3.8? This is not supported. – Cow Commented Nov 22, 2024 at 6:32
• I have 3 environments, 3.6, 3.7, 3.8, all the same situation. – Chuckie Zhu Commented Nov 22, 2024 at 6:38
• All right, that's valuable info to have. – Cow Commented Nov 22, 2024 at 6:41
• thanks, I fot to add this to this post, I just added it. – Chuckie Zhu Commented Nov 22, 2024 at 6:45

I know why!!!

I had an assume: some games were imported successfully, but the retor's list_game cannot list it, so I want to figure out which game was imported but unlisted.

When I manually imported those games, I found many games in the ROMs have same name, forexample, "Robotank" occur 3 times, that's why I imported 167 games, but only have 59 in list. because there are same games in the ROMs. I use this ROMs.
