A student implementation of the World Models paper with documentation.
Ongoing project.
- β-VAE for the Visual model
- MDN-LSTM for the Memory model
- CMA-ES for the Controller model
- Training pipelines for the 3 models
- Human recordings to generate data
- MongoDB to store data
- LSTM and VAE trained "successfully"
- Multiprocessing of the evaluation of a set of parameters given by the CMA-ES
- Submit learnt agents
- Cleaner code, more optimized and documented
- Game agnostic
- Continue training / testing better architectures
- Online training instead of using a database
- Install the modules in the requirements.txt, pytorch 0.4 and mongoDB
- Buy or find the ROMs of Sonic The Hedgehog and install them with retro-gym.
Once you've done that, you will need to train the 3 components :
python train_vae.py
python train_lstm.py --folder=xxx
python train_controller.py --folder=xxx where xxx is the folder number created in saved_models/
While training the VAE and the LSTM, pictures will be saved in a folder results/
Once you're done, you can use your best trained controller to play a random level using :
python play_best --folder=xxx
Dont forget to change the RENDER_TICK in const.py to 1, so you can see what's happening.
- My write-up on the code and concepts of this repository
- World Models paper
- Coded on Ubuntu 16.04, Python 3.5, PyTorch 0.4 with GPUs (some change have to be made in order to make it fully compatible to CPU as well, such as adding a map_location="cpu" when loading the model)
- No temperature
- No flipping of the loss sign during training (to encourage exploration)
- β-VAE instead of VAE
