unable to run the Diambra environment.

[sramichetty20019]

Hi, everyone I am trying to get the Diambra arena running but I encountered the following issue; the Diambra engine starts but crashes right after , I believe it is because of the opt directory that Diambra needs access to I tried to grant the permission but it still gives me the same error is there a work around I am pasting my error below, kindly let me know how to solve this.

:~/arena/diambra$ diambra run -r /home/srinija/arena/diambra/arena/doapp python test.py

Hi @sramichetty20019, thanks for reaching out. Have you placed the game ROM file into the roms directory?

[sramichetty20019]

@alexpalms thank you so much for replying.

that's the part I was bit confused I just extracted the zip file and placed its contents in /home/srinija/arena/diambra/arena and then I ran the command diambra run -r /home/srinija/arena/diambra/arena/doapp python test.py so should I create or make directory in the /home/srinija/arena/roms and then run it? Also, if it is placed in the opt directory then wouldn't there be permission issues? Where exactly should this roms directory be?

[alexpalms]

@sramichetty20019 no need to unzip the file, keep it zipped, in the case of Dead or Alive, keep it as doapp.zip.

You just place the zip file itself in a folder that you will define as you "roms folder" and that you pass to the command line application using the -r parameter as you are doing.

It should solve your problem.

The opt folder is the one inside the docker container, where your roms folder is mounted.

Try this and let us know ;)

@alexpalms thank you so much I just made the changes as mentioned and now it works perfectly well! Thank you once again.
