This porject presents the classic game of Tetris built using PyGame whcich makes use of anm agente to learn trough human data how to play this mytical game.
main.py for playing Tetris manually.
main_imitation.py for training and data collection Imitation learning.
The different modes of use can be applied by modifying the following functions:
if __name__ == "__main__":
train() # Trains and validate the model using data acquired playing
model.save_weights() # Save the model weigths
model.load_weights('_10k_01_nat1') # Load the model weigths
main() # Shows a model trained or allow the user to play and generate new data
generate_data(400) #Generates sinthetic data using a natural selection algorithmIf the process you wanna do is take data, you must select in main_imitation.py.
def main(manual=1): # Manual=1(user data acquisition)dfdfdfdfdfdfdfdfddffdfdf3232343242
To edit Tetris behaviour change contructor params.
env = Tetris({
'reduced_shapes': True,
'reduced_grid': True
})Where reduced_shapes control the type of pieces used in the learning process and reduced_grid control de type of grid.
Enviorment follows regular OpenAI standard.
from enviorment.tetris import Tetris
from Imitation.agent import imitation_agent
from nat_selection.model import Model
from dqn.agent import DQN
env = Tetris()
# Agent can either be custom.
agent = imitation_agent(env)
total_score = 0
state, reward, done, info = env.reset()
while not done:
# for random action
action = env.action_sample
# for agent action
# Be aware that different agents have different methods of getting the next action.
action = agent.policy(state)
state, reward, done, info = env.step(action)
total_score += reward
env.render()State is a three dimensional array with 2 layers representing the placed blocks and the ones you are controlling. Blocks are 1 and blank cells are 0.
Loading pretrained models can be done like this.
from enviorment.tetris import Tetris
from Imitation.agent import imitation_agent
from nat_selection.model import Model
from dqn.agent import DQN
env = Tetris()
# Imitation
agent = imitation_agent(env)
agent.load_weights('_10k_01_nat1')
# Where the argument is the suffix after "weights" in ./Imitation/weightsFor installation, enter the directory
