How was tt1.pb trained?

[noelcodes]

I need to track heads, instead of person. I have used your tracker, but it keep switching ID even without occlusion. My suspect is tt1.pb was trained on "person" data only (correct me if i'm wrong). Therefore I planned to re-train a new "tt1.pb" with only "heads" dataset. Can you share the details about tt1.pb's architecture, which model, what dataset, train codes...etc... ? Thanks. Great work btw.
