Model is installed but doesnt load when opened as an app

[Akshathar8]

The frozen_har.pb created following your tutorial doesn't work. also the frozen_har.pb on your github repo aslo doens't work. I am implementing this solution on a critical project. Please help me.

It gives out this error:

Please help me. I am using this solution for a critical project of mine.
