 ```python
-import requests

-import torch

-
-model_id = "IDEA-Research/grounding-dino-tiny"

-image_url = "http://images.cocodataset.org/val2017/000000039769.jpg"
-image = Image.open(requests.get(image_url, stream=True).raw)
-# Check for cats and remote controls
-text = "a cat. a remote control."
-
-inputs = processor(images=image, text=text, return_tensors="pt").to(device)
-with torch.no_grad():
-    outputs = model(**inputs)
-
-results = processor.post_process_grounded_object_detection(
-    outputs,
-    inputs.input_ids,
-    box_threshold=0.4,
-    text_threshold=0.3,
