ROM file wont load

[citynorman]

Here's what I did:

1. download https://atariage.com/2600/roms/Breakout.zip and extract to deep_q_rl/roms
   2A) run deep_q_rl/deep_q_rl/run_nips.py --rom Breakout (ie upper case)
   2B) rename Breakout.bin to breakout.bin (lower case) and run deep_q_rl/deep_q_rl/run_nips.py --rom breakout

Be good to add those steps to dep_script.sh

Have you downloaded the ROM file? ROMS need to be obtained separately. E.g.:

https://atariage.com/2600/roms/Breakout.zip

Whoah thanks for the speedy response!

I downloaded the file and added it to the roms directory. I have tried running the file as both a .bin and .zip. Perhaps it has something to do with the fact that it cant find the stellarc file?

This is related to the ALE. You should try to rename your ROM to breakout.bin. The ROM should be on the lowercase. The ALE expects a specific filename containing each of the ROMs.

[arccoxx]

The file is now named: "breakout.bin". But still it's giving me the same error.

It doesn't look like an ALE error then. The issue with ROMs have been addressed in this post: https://groups.google.com/forum/#!topic/arcade-learning-environment/1IL4dnLSpfo

I don't want to state the obvious, but did you check if the code is properly receiving this parameter? And if the obvious thing is if the file is where you are defining it.

I responded here because I thought it could be an ALE error, but it seems it is not.

You can also test the ROM by downloading Stella separately, on your laptop,
etc. That will tell you whether the ROM is good.

Intuitively, I agree that most likely error is it not looking for the right
file, somewhere in code. I'd grep for it...

Best,

groovy thanks

The code is configured to expect the ROM file to be stored in the existing folder named "roms". The default location is configurable in the executable scripts.

[stone8oy]

well, you just need to copy the file " stellarc" ( listed in last :
https://github.com/stone8oy/deep_q_rl/tree/master/deep_q_rl ) to that
directory,

No word on this for a while, and no one else has reported a problem. I'm closing the issue.
