How to use HuggingFaceTB/SmolVLM2-2.2B-Instruct with Transformers:

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

pipe = pipeline("image-text-to-text", model="HuggingFaceTB/SmolVLM2-2.2B-Instruct")
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)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("HuggingFaceTB/SmolVLM2-2.2B-Instruct")
model = AutoModelForMultimodalLM.from_pretrained("HuggingFaceTB/SmolVLM2-2.2B-Instruct")
messages = [
    {
        "role": "user",

            {"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=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Hi there,

I have this error when I try to run model in Google Colab.

Do you have a solution for this?

/usr/local/lib/python3.11/dist-packages/transformers/models/smolvlm/video_processing_smolvlm.py in smolvlm_sample_indices_fn(metadata, max_frames, target_fps, skip_secs)
     56 
     57     total_num_frames = getattr(metadata, "total_num_frames", 0)
---> 58     if total_num_frames <= 0:
     59         raise ValueError(f"Invalid total_num_frames={total_num_frames} in metadata.")
     60 

ValueError: Invalid total_num_frames=0 in metadata.

I have the same problem.
I found that even though they are all MP4 files, certain specific files cause the error "Invalid total_num_frames=0 in metadata."
