This model was trained with a superset of 300,000 instructions in Portuguese. The model comes to help fill the gap in models in Portuguese. Tuned from the Llama-2-13b

How to use

FULL MODEL : A100

HALF MODEL: L4

8bit or 4bit : T4 or V100

You can use the model in its normal form up to 4-bit quantization. Below we will use both approaches. Remember that verbs are important in your prompt. Tell your model how to act or behave so that you can guide them along the path of their response. Important points like these help models to perform much better.

!pip install -q -U transformers
!pip install -q -U accelerate
!pip install -q -U bitsandbytes

from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer
model = AutoModelForCausalLM.from_pretrained("rhaymison/portuguese-tom-cat-13b", device_map= {"": 0})
tokenizer = AutoTokenizer.from_pretrained("rhaymison/portuguese-tom-cat-13b")
model.eval()

You can use with Pipeline.

from transformers import pipeline
pipe = pipeline("text-generation",
                model=model,
                tokenizer=tokenizer,
                do_sample=True,
                max_new_tokens=512,
                num_beams=2,
                temperature=0.3,
                top_k=50,
                top_p=0.95,
                early_stopping=True,
                pad_token_id=tokenizer.eos_token_id,
                )

  """

  return _input.strip()

prompt = "Me explique sobre os romanos"
pipe(format_question(prompt))

Os romanos foram um povo que viveu na Itália antiga, entre o século VIII a.C. e o século V d.C.
Eles eram conhecidos por sua habilidade em construir estradas, edifícios e aquedutos, e também por suas conquistas militares.
O Império Romano, que durou de 27 a.C. a 476 d.C., foi o maior império da história, abrangendo uma área que ia da Grécia até a Inglaterra.
Os romanos também desenvolveram um sistema de leis e instituições políticas que influenciaram profundamente a cultura ocidental.

If you are having a memory problem such as "CUDA Out of memory", you should use 4-bit or 8-bit quantization. For the complete model in colab you will need the A100. If you want to use 4bits or 8bits, T4 or L4 will already solve the problem.

4bits example

from transformers import BitsAndBytesConfig
import torch
nb_4bit_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16,
    bnb_4bit_use_double_quant=True
)

model = AutoModelForCausalLM.from_pretrained(
    base_model,
    quantization_config=bnb_config,
    device_map={"": 0}
)
