### Usage
|
|
|
|
|
|
```python
|
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|
|
from PIL import Image
|
|
|
|
|
|
model = AutoModelForCausalLM.from_pretrained(
|
|
|
"vikhyatk/moondream2",
|
|
|
revision="2025-06-21",
|
|
|
trust_remote_code=True,
|
|
|
# Uncomment to run on GPU.
|
|
|
# device_map={"": "cuda"}
|
|
|
)
|
|
|
|
|
|
# Captioning
|
|
|
print("Short caption:")
|
|
|
print(model.caption(image, length="short")["caption"])
|
|
|
|
|
|
print("\nNormal caption:")
|
|
|
for t in model.caption(image, length="normal", stream=True)["caption"]:
|
|
|
# Streaming generation example, supported for caption() and detect()
|
|
|
print(t, end="", flush=True)
|
|
|
print(model.caption(image, length="normal"))
|
|
|
|
|
|
# Visual Querying
|
|
|
print("\nVisual query: 'How many people are in the image?'")
|
|
|
print(model.query(image, "How many people are in the image?")["answer"])
|
|
|
|
|
|
# Object Detection
|
|
|
print("\nObject detection: 'face'")
|
|
|
objects = model.detect(image, "face")["objects"]
|
|
|
print(f"Found {len(objects)} face(s)")
|
|
|
|
|
|
# Pointing
|
|
|
print("\nPointing: 'person'")
|
|
|
points = model.point(image, "person")["points"]
|
|
|
print(f"Found {len(points)} person(s)")
|
|
|
```
