Compiling Issues

[2020chris]

I am having some issues compiling and running main.py, as it is saying it can't find the pathFinder module. Can main.py be compiled in both python2 and python3?

Use python2.7.

I'm getting an error re print when using python3 so I can't reproduce what you're seeing.

Also, in case you get it working, make sure you set load_model to False on first run.

Thanks for the reply. I assume I need to re-install torch with python2.7 also?

Should it be able to start training off the bat by running python main.py? Or do I need to run setup.py to compile and create the extension for pathFinder.cpp? If you could detail some of the intermediate steps to start training(eg. building the pathFinder module), that would be great!

Yup, you need to install torch for python2.7 as well.

pathFinder is already compiled for you here and you should be able to run the code out of the box on a Linux machine.

Haven't tried any other OS but have you seen setup.py:

# $ python setup.py build
# $ sudo python setup.py install
# $ sudo rm -rf build
...

Yes it started training. Is it possible to run on GPU currently? Since I was having compatibility issues with Python2.7, PyTorch 1.4, and CUDA 11.4 in my conda env.

Also, can you explain how you structured/represented the board you pass to the QuoridorNNet, specifically the dimensions 4xnxn of the pieces field of the Board class? Thanks.

Yes, you can train on GPU, I trained my own model using Colab.

You're gonna have to more specific.

If you're still interested, I updated the code so it works with python3: https://github.com/Mihonarium/alphazero-quoridor
