	## Generate Qwen VL Checkpoint (for In-Framework Deployment)
	This checkpoint is used for in-framework deployment examples.
	3. Run the following Python code to generate the NeMo 2.0 checkpoint:
	```python
	from nemo.collections.llm import import_ckpt
	from nemo.collections import vlm
	from pathlib import Path
	if __name__ == '__main__':
	# Specify the Hugging Face model ID
	hf_model_id = "Qwen/Qwen2.5-VL-3B-Instruct"
	# Import the model and convert to NeMo 2.0 format
	import_ckpt(
	model=vlm.Qwen2VLModel(vlm.Qwen25VLConfig3B(), model_version='qwen25-vl')
	source=f"hf://{hf_model_id}", # Hugging Face model source
	output_path=Path('/opt/checkpoints/qwen25_vl_3b')
	)
