Hi @agnes-hsq, thanks for getting in touch. As the Python API is part of the Tobii Pro SDK, it may be worth asking the Tobii Pro Support team directly about this issue @ http://www.tobiipro.com/contact/contact-support/
As you have purchased the special licence, you should be entitled to deal with the team there directly. Please however do let us know how you get on here for the benefit of any other users 🙂
