Lloro 7B
Lloro, developed by Semantix Research Labs , is a language Model that was trained to effectively perform Portuguese Data Analysis in Python. It is a fine-tuned version of codellama/CodeLlama-7b-Instruct-hf, that was trained on synthetic datasets. The fine-tuning process was performed using the QLORA metodology on a GPU A100 with 40 GB of RAM.
Model description
Model type: A 7B parameter fine-tuned on synthetic datasets.
Language(s) (NLP): Primarily Portuguese, but the model is capable to understand English as well
Finetuned from model: codellama/CodeLlama-7b-Instruct-hf
What is Lloro's intended use(s)?
Lloro is built for data analysis in Portuguese contexts .
Input : Text
Output : Text (Code)
Usage
Using Transformers
#Import required libraries
import torch
from transformers import (
AutoModelForCausalLM,
AutoTokenizer
)
#Load Model
model_name = "semantixai/LloroV2"
base_model = AutoModelForCausalLM.from_pretrained(
model_name,
return_dict=True,
torch_dtype=torch.float16,
device_map="auto",
)
#Load Tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
#Define Prompt
user_prompt = "Desenvolva um algoritmo em Python para calcular a média e a mediana dos preços de vendas por tipo de material do produto."
system = "Provide answers in Python without explanations, only the code"
prompt_template = f"[INST] <<SYS>>\\n{system}\\n<</SYS>>\\n\\n{user_prompt}[/INST]"
#Call the model
input_ids = tokenizer([prompt_template], return_tensors="pt")["input_ids"].to("cuda")
outputs = base_model.generate(
input_ids,
do_sample=True,
top_p=0.95,
max_new_tokens=1024,
temperature=0.1,
)
#Decode and retrieve Output
output_text = tokenizer.batch_decode(outputs, skip_prompt=True, skip_special_tokens=False)
display(output_text)
Using an OpenAI compatible inference server (like vLLM)
from openai import OpenAI
client = OpenAI(
api_key="EMPTY",
base_url="http://localhost:8000/v1",
)
user_prompt = "Desenvolva um algoritmo em Python para calcular a média e a mediana dos preços de vendas por tipo de material do produto."
completion = client.chat.completions.create(temperature=0.1,frequency_penalty=0.1,model="semantixai/Lloro",messages=[{"role":"system","content":"Provide answers in Python without explanations, only the code"},{"role":"user","content":user_prompt}])
