Llama-2-7B-instruct-text2sql-GPTQ Model Card

Model Name: Llama-2-7B-instruct-text2sql-GPTQ

Description: This model is a GPTQ quantisation of a fine-tuned version of the Llama 2 with 7 billion parameters, specifically tailored for text-to-SQL tasks. It has been trained to generate SQL queries given a database schema and a natural language question. The GPTQ quantisation was performed with AutoGPTQ.

Example Code

You can use the Llama-2-7B-instruct-text2sql-GPTQ model to generate SQL queries from natural language questions, as demonstrated in the following code snippet:

pip install -q transformers==4.35.0 torch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 optimum==1.13.2 auto-gptq==0.4.2

from transformers import AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM

model_name = 'support-pvelocity/Llama-2-7B-instruct-text2sql-GPTQ'

model = AutoGPTQForCausalLM.from_quantized(model_name, use_safetensors=True, device_map='auto')
tokenizer = AutoTokenizer.from_pretrained(model_name)

table = "CREATE TABLE sales ( sale_id number PRIMARY KEY, product_id number, customer_id number, salesperson_id number, sale_date DATE, quantity number, FOREIGN KEY (product_id) REFERENCES products(product_id), FOREIGN KEY (customer_id) REFERENCES customers(customer_id), FOREIGN KEY (salesperson_id) REFERENCES salespeople(salesperson_id)); CREATE TABLE product_suppliers ( supplier_id number PRIMARY KEY, product_id number, supply_price number, FOREIGN KEY (product_id) REFERENCES products(product_id)); CREATE TABLE customers ( customer_id number PRIMARY KEY, name text, address text ); CREATE TABLE salespeople ( salesperson_id number PRIMARY KEY, name text, region text ); CREATE TABLE product_suppliers ( supplier_id number PRIMARY KEY, product_id number, supply_price number );"

question = 'Find the salesperson who made the most sales.'

prompt = f"[INST] Write SQLite query to answer the following question given the database schema. Please wrap your code answer using ```: Schema: {table} Question: {question} [/INST] Here is the SQLite query to answer to the question: {question}: ``` "

tokens = tokenizer(prompt, return_tensors="pt").to('cuda:0')
input_ids = tokens.input_ids

generated_ids = model.generate(input_ids=input_ids, max_length=4048, pad_token_id=tokenizer.eos_token_id)
output = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
output = output.split('```')[2]
print(output)

This code demonstrates how to utilize the model for generating SQL queries based on a provided database schema and a natural language question. It showcases the model's capability to assist in SQL query generation for text-to-SQL tasks.
