I can not play matches between versions:

Once you have a set of training models, copy directories under ~run/ to ~run_archive/connect4/run001/, then you should be able to play.

I added a little script in my fork (play_game.py) for a better interface of human playing against AI. See: https://github.com/ezrahn/DeepReinforcementLearning

There are bugs in the initial game model, including

• Being able to place a coin hanging in the air, while the original connect 4 is played on a vertical board where the coins fall due to gravity.
• Human player can place a coin that is already filled, e.g. no input validation yet.

Will try to fix these and contribute back.

I just added the validation for human player moves, and a better interface for human to interact with the game. Once the model is trained, copy directories under ~run/ to ~run_archive/connect4/run001/.

To play the game, run: python play_game.py See: https://github.com/ezrahn/DeepReinforcementLearning

Sorry for the late reply. I do fix the bug through your instruction, but i found my MacBook Pro can not afford this GPU-hungry program. Thanks anyway.

Hello, i have the same problem as SCoulY with

OSError: Unable to open file (unable to open file: name = './run_archive/connect4/run0001/models/version0001.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)

What exactly is the version0001.h5 file?

Thanks for help

Hey, ezrahn I met exact the same problem

OSError: Unable to open file (unable to open file: name = './run_archive/connect4/run0001/models/version0001.h5', errno = 2, error message = 'No such file or directory', flags = 0, o_flags = 0)

I've first run the training, but terminate the run before any model file created, now I'd like to restart training again, then above fail popup, any way to solve this?

thanks

My problem is I model.save_model("model"). It kind shows it's in .h5 format with actually without the extension. When I just write loaded_model = load_model('model'), everything works.
