After you've installed python 3.5, numpy, tensorflow, keras and h5py, download and unzip hmate9's replay cache (the Dropbox cache doesn't work anymore, see hvaara's solution: #9):
Run the bot on to mimic the winner of each replay:
python train_bot.py ./replays
Add hlt.py, networking.py, model.h5, LANGUAGE, and MyBot.py to MyBot.zip and submit to halite.io
