need evaluator code reference for object detector & zero shot object dector task

Hi Team,

i use google/owlvit-base-patch32 model for zero shot object detection.

To evaluate the model performance and speed, i like to use a evaluator for Zero Shot Object Detector task.

Currently it is supported only for limited tasks ( https://huggingface.co/docs/evaluate/base_evaluator) .

Like to know is there any evaluator available for ( Zero Shot Object Detector tasks)

https://www.philschmid.de/optimizing-transformers-with-optimum contains this code for text-classification task.

thanks
