project Type: Object Detection Using Grounding DINO with prompts.

I am using the Grounding DINO model on google Colab. The notebook I got from the roboFlow GitHub repository.

**First problem:** It arises when installing the Grounding DINO model in Google Colab environment. It throws an error saying _This error originates from a subprocess, and is likely not a problem with pip._

**Second problem:** While applying the model on an image (uploaded) by me, it throws warnings as well as an error statement saying: _name ‘\_C’ is not defined_
