Libraries

How to use nvidia/Flora-Captioner with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="nvidia/Flora-Captioner")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("nvidia/Flora-Captioner")
model = AutoModelForMultimodalLM.from_pretrained("nvidia/Flora-Captioner", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Adds the TempSeg-to-Captioner inference examples from flora-share/Flora-Captioner-Release-Infer@657752f279164052d2acb22da11dfcf97207d680. Binds the examples to immutable NVIDIA revisions with corrected model-card checksums. This PR and the corresponding nvidia/Flora-TempSeg PR are a paired update.

The existing model card, weights, provenance, licenses, configuration, and templates are preserved. Only the model-card checksum entry changes among existing files. Static syntax, code-manifest, vendor-manifest, and model-asset identity checks passed; CUDA inference was not run. Keep the referenced PR commits available; if the merge strategy does not retain them, update both revision pins before deleting the PR refs.
