 # Using the model 
 
-## Converting from T5x to huggingface
+You should ask specific questions to the model in order to get consistent generations. Here we are asking the model whether the sum of values that are in a chart are greater than the largest value.
+
+```python
+from transformers import Pix2StructProcessor, Pix2StructForConditionalGeneration
+import requests
+from PIL import Image
+
+processor = Pix2StructProcessor.from_pretrained('google/matcha-plotqa-v2')
+model = Pix2StructForConditionalGeneration.from_pretrained('google/matcha-plotqa-v2')

+url = "https://raw.githubusercontent.com/vis-nlp/ChartQA/main/ChartQA%20Dataset/val/png/20294671002019.png"
+image = Image.open(requests.get(url, stream=True).raw)

+inputs = processor(images=image, text="Is the sum of all 4 places greater than Laos?", return_tensors="pt")

+print(processor.decode(predictions[0], skip_special_tokens=True))

 You can use the [`convert_pix2struct_checkpoint_to_pytorch.py`](https://github.com/huggingface/transformers/blob/main/src/transformers/models/pix2struct/convert_pix2struct_original_pytorch_to_hf.py) script as follows:
