Data

Download target templates here, and put the folder diff_phys that contains goal shapes onto your machine.

Experiments

Run the following to train an agent that writes "ICLR" on a plasticine board:

python3 scripts/launch_training.py \
--root_dir somewhere_on_your_machine/diff_phys \
--algo cpdeform \ 
--env_name multistage_writer

The experiment results will be stored in the diff_phys folder.

Acknowledgements

Our physics simulation is based on PlasticineLab.
