API Issue with current Codebase

[augsaksham]

There are two issues currently that are present in the API.

1. The efficientdent model servable is missing in the saved model directory this causes the failure of object detection API.
2. SceneTextVideo is not working on ubuntu 20.04 (possibly taking too long to run so the process is being killed) .
