How to connect Pupil Core eyetracking to ioHub

I have tried to use the .yaml file to set up my environment for eyetracking experiment. I only have a Network API address for connecting to ioHub. So I referred to the SR_reasearch.yaml file.
enable_interface_without_connection: True
network_settings: tcp://
but it didn’t work. when I run the code: io = client.ioHubconnection(io_config), my computer stopped to run the script and no response for psychopy.

Pupil Core is not supported by iohub. iohub currently supports EyeLink, GP3, and Tobii eye trackers. Thank you.
