• I have attempted to remove unused code. Please verify the changes.
• Consider writing some instructions on Track2 for participants.
• Consider writing a README.md explaining how to use the training code.
• Consider writing a README.md explaining how to make a submission for Track2. If there are any specific interfaces or requirements which the participant submitted code must follow in order for you to re-train and re-test their code, consider specifying those interfaces and requirements in Codalab Track2 description.
