A: Let's find the column of republicans. Then let's extract the favor rates, they [45.0, 42.0, 38.0, 49.0, 51.2, 48.0, 41.0]. The smallest number is 38.0, that's Row 3. Row 3 is year 2007. The answer is 2007. Q: What is the sum of Democrats' favor rates of 2004, 2012, and 2013? A: Let's find the rows of years 2004, 2012, and 2013. We find Row 1, 6, 7. The favor dates of Demoncrats on that 3 rows are 68.1, 70.0, and 72.0. 68.1+70.0+72=210.1. The answer is 210.1. Q: By how many points do Independents surpass Republicans in the year of 2011? A: Let's find the row with year = 2011. We find Row 5. We extract Independents and Republicans' numbers. They are 58.0 and 51.2. 58.0-51.2=6.8. The answer is 6.8. Q: Which group has the overall worst performance? A: Let's sample a couple of years. In Row 1, year 2004, we find Republicans having the lowest favor rate 45.0 (since 45.0<68.1, 45.0<53.0). In year 2006, Row 2, we find Republicans having the lowest favor rate 42.0 (42.0<58.0, 42.0<53.0). The trend continues to other years. The answer is Republicans. Q: Which party has the second highest favor rates in 2007? A: Let's find the row of year 2007, that's Row 3. Let's extract the numbers on Row 3: [59.0, 38.0, 45.0]. 45.0 is the second highest. 45.0 is the number of Independents. The answer is Independents. {_INSTRUCTION}""" def text_generate(prompt, table, problem): p = prompt + "\n" + table + "\n" + "Q: " + problem # print(f"Final prompt is : {p}") json_ = {"inputs": p, "parameters": { "top_p": 0.9, "temperature": 1.1, "max_new_tokens": 128, "return_full_text": True }, "options": { "use_cache": True, "wait_for_model":True },} response = requests.post(API_URL, headers=headers, json=json_) print(f"Response is : {response}") output = response.json() print(f"output is : {output}") #{output}") output_tmp = output['generated_text'] print(f"output_tmp is: {output_tmp}") #solution = output_tmp.split("\nQ:")[0] #output[0]['generated_text'].split("Q:")[0] # +"." #print(f"Final response after splits is: {solution}") #return solution return output_tmp model_deplot = Pix2StructForConditionalGeneration.from_pretrained("google/deplot") processor_deplot = Pix2StructProcessor.from_pretrained("google/deplot") def process_document(image, question): # image = Image.open(image) inputs = processor_deplot(images=image, text="Generate the underlying data table for the figure below:", return_tensors="pt") predictions = model_deplot.generate(**inputs) table = processor_deplot.decode(predictions[0], skip_special_tokens=True) # send prompt+table to LLM res = text_generate(_TEMPLATE, table, question) print (res) description = "Demo for deplot+llm for QA or summarisation.
