PyTrack - ModuleNotFound Error

Hey everyone, hope you are doing great!

I write this post to ask for an introduction into python software with which I can visualise and analyse eye-tracking data that can also spit out info on pupil dilation. I already found PyTrack but after installing I get the ModuleNotFound error, even though I have that init file in the folder and manually downloaded the most current files to the Pytrack folder from GitHub. Is there something else I can do or a better software I could use?

We use a Long Range Mount MEG compatible Eyelink 1000 Plus:

Thank’s a lot in advance! Have a nice day everyone!
