How to run python example on Linux

[4SkyNet]

Hi, I've got some troubles with the given example in:

~/doc/examples

I try to run:

python_example.py path_to_game_rom

But it fails with issues wrt argv[2], where I should provide some core_file (*.so)

I try again:

python_example.py path_to_game_rom path_to_librle_c.so

But it fails again with this error:

Failed to load symbol 'retro_init'': ../../rle_python_interface/librle_c.so: undefined symbol: retro_init

It seems to that there should be some corrections wrt symbols
(it can be linux specific as previous commit to setup.py from my buddy)

The .so file should be of the core (Atari or Snes).
For snes it should be in snes9x2010/snes9x2010-libretro.so.

I'll add the instructions to help avoid confusion.

Thx, it loads! ...but then I've got a segmentation fault

Sorry for the delayed response, didn't notice your comment earlier.
Please give it another try and let me know if you still have this issue.

I also got the same error with v1.0.2 .

Please make sure that the name of the rom on your file system is identical to that in the rom file.

Thank you very much @nadavbh12, I am able run the example code now.

Supposedly, tutorial, more examples, and how to use the RLE can be found in the ALE?

[nadavbh12]

You're welcome.
Not sure what you're asking. Could you rephrase that?

[tohnperfect]

Where I could find more examples and tutorial of your library? Should I start with the ALE? Thank you for making this great library.

Basically any repository you find online which uses ALE can easily be replaced by RLE.
You can check out this fork of deep_q_rl to run DQN with RLE.

Great! Thank you very much for the pointer.
