Importing Atari Games with python -m retro.import about retro HOT 35 CLOSED

Thank you very much! It amazingly worked. And for more people who have the same issue. Here is a detailed tutorial:

1. Download zip file from http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html
2. Open Roms.rar > ROMS.rar and find Space Invaders (1980) XXXXXX
3. Extract all matches (there are 5 of them) into your destin folder
4. python -m retro.import . (don't forget the point)
5. One of them worked! And continue with the amazing tutorial here: https://github.com/simoninithomas/Deep_reinforcement_learning_Course/blob/master/DQN/Space%20Invaders/DQN%20Atari%20Space%20Invaders.ipynb

Hello @MaximusWudy , thanks for your message 😊

Effectively, you need to import the roms.

I found the roms here http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html, by the way you will not need to rename the files.

You just need to go to the folder were you unzipped your roms and write python -m retro.import . (don't forget the point)

Then, when the roms are imported you will be able to use Atari Space invaders (restart you jupyter notebook).

If you have other questions feel free to ask!

Have a great day,

from retro.

For those who struggle to use it in colab:

1. !wget http://www.atarimania.com/roms/Roms.rar
   Make sure that Roms.rar appeared in files
2. !unrar x /content/Roms.rar
   There are must be 2 zip archives: ROMS.zip and HC ROMS.zip
3. !unzip /content/ROMS.zip
ROMS folder must appear
4. !pip install gym-retro
   Install retro package
5. !python3 -m retro.import ROMS/
   Import environments
6. env = retro.make(game="SpaceInvaders-Atari2600")
   Create environment!

Hi Thomas,

      It's amazing that I am studying your tutorial right now and encounter the same problem! Could you please be more specific about which ROM is a good version. Or could you please attach the ROM file into your github folder?

     I really appreciate your tutorial and look forward to more in the future. Thank you!

Ok I see now what someone else was attempting to state above in the posts with a .

I added this into my terminal command python -m retro.import . and now I can see a
Importing 4 potential games, imported 0 games

And I still have the same error trying to run Thomas's code :( Any ideas? Thank you...

from retro.

I found why 🎉. it's because you need the good version of the rom, however with Atari 2600 you have tons of different versions (PAL, NTSC, Hack, Non hack) etc.

** If you have the same problem, be sure to download the good version of the rom 😄**

I close the issue

from retro.

@RinshannKaihou for me, the solution was using the 1983 space invaders version: "Space Invaders (1983) (CCE) (C-820).bin" NOT any of the 1980 versions. If you copy all 5 space invader titles it reads:

Importing 5 potential games...
Importing SpaceInvaders-Atari2600
Imported 1 games

from retro.

you guys need to specify the path you put your files.then run the terminal command.for me it is like python -m retro.import C:\Users\GHOST\Documents\AI_tensorflow\Lib\site-packages\gym_retro-0.6.0.dist-info

hope this helps

@simoninithomas Can't we just use gym?
import gym
env = gym.make('SpaceInvaders-v0')

Is there a difference in the gym-retro and gym environments?

from retro.

There is no license. I'm pretty sure it's copyright infringement to download and distribute them. However, for a good many of them there isn't a real risk due to the IP being old enough that no one really cares or they're in limbo. For newer games it's rougher, which is why when I made the Retro Contest, I promoted the use of ROMs you could buy on Steam without legal concerns.

Thanks @MaximusWudy , I am also studying simoninithomas's tutorial and search for the Atari game rom and finally find this.

Hi, I was also facing same issue. But when i tried to do "python -m retro.import . (don't forget the point)" i was getting Importing 0 potential games, imported 0 games. Can you tell me what i am doing wrong?

from retro.

Hi, @seshuthota what game you're trying to import ?

from retro.

I was trying to import Space Invaders. First i downloaded file from this page http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html

I extracted and inside ROMS folder i found 5 files naming Space Inavders and i copied them to this path
Anaconda3\Lib\site-packages\retro\data\SpaceInvaders-Atari2600 and in the command prompt i tried this command "python -m retro.import" but it is printing "Importing 0 potential games, Imported 0 games". What did i do wrong here?
Did i got the wrong files? i have attached the files that i was copying.
SpaceInavdersGameFiles.zip

from retro.

Hi,
Simply unzip the total archive in a folder go to this folder and type python -m retro.import . (dont forget that point !!!)

from retro.

Hi Im struggling with this same thing.. I even tried this process 2 times:

1. I downloaded these files as posted above http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html
2. Copied the roms.rar download file to my desktop and right click extract in Linux Mint v18
3. I have Anaconda 3.6 installed and then right click open in terminal on the new extracted folder python -m retro.import

Importing 0 potential games, imported 0 games

Can someone tell me what I am doing wrong???

from retro.

You need to add . at the end of the script. It needs a directory name. (I've just pushed changes that let it use files and will search the current directory if no arguments are passed but this isn't in the stable build.)

from retro.

Very important note:
If the ROM has a .bin extension, rename it to have the correct extension for that system.

Hi @bbartling I'm facing the same issue.

(tensorflow) D:\Anaconda3\Lib\site-packages\retro\data\SpaceInvaders-Atari2600>python -m retro.import . Importing 4 potential games... Imported 0 games

Have you found the reason?

from retro.

@RinshannKaihou no I have not...

from retro.

you need cd to fold ....../Roms/ROMS ,and then do the following:

pip3 install gym-retro
python3 -m retro.import

@RinshannKaihou

from retro.

I see no module named retro. Could someone please help

from retro.

For Google Colab Notebooks do the following.

! wget http://www.atarimania.com/roms/Roms.rar && unrar x Roms.rar && unzip Roms/ROMS.zip
! pip3 install gym-retro
! python3 -m retro.import ROMS/

Didn't work for me...

didnt work for me on google colab... dont know what to do.

from retro.

Hi,
Simply unzip the total archive in a folder go to this folder and type python -m retro.import . (dont forget that point !!!)

when you say "dont forget the point", do you mean the point between "retro" and "import", and the point after "import" is just for closing the sentence, or do you mean not forgetting the point after "import"? also, shouldn't we specify a path?

from retro.

The point after import. That is the path.

from retro.

This is how I solved it.

1. Downloaded Atari ROMs from here
2. Extracted to any place. Opened and found "Space Invaders (1983) (CCE) (C-820).bin".
3. Extracted the file in the same directory as my python script.
4. python -m retro.import . in the same location where I would run the script.

from retro.

Hi,

Thanks for the solution. Any idea what is the license for these ROMs? Stella is on GNU and Retro is on MIT licenses, but I am not sure about the ROMs. I have seen people use these ROMs for publications but I haven't seen the licenses in their codebases.

Any help would be great

from retro.

Thanks a lot. This helps 👍

Change link to http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html . Worked for me

from retro.

This might help someone working in colab; creating a new directory works for me

! wget http://www.atarimania.com/roms/Roms.rar && unrar x Roms.rar 
!mkdir <new_dir>
!unzip Roms/ROMS.zip -d <new_dir>
! pip install gym-retro

hey, did you manage to solve this issue with colab ?

unfortunately, it didn't work for me. i had this error message : FileNotFoundError: Game not found: SpaceInvaders-Atari2600. Did you make sure to import the ROM?
