This is a fine-tuned version of the Llama-3.1-8B-Instruct model, specialized in assigning a date to Greek documentary papyri. On a test set of 2,295 unseen papyri its predictions were, on average, 21.7 years away from the actual date spans. See https://arxiv.org/abs/2409.13870.

Dataset

This model was finetuned on the Ericu950/Papyri_1 dataset, which consists of Greek documentary papyri editions and their corresponding dates and geographical attributions sourced from the amazing Papyri.info.

Usage

To run the model on a GPU with large memory capacity, follow these steps:

1. Download and load the model

python

import json
from transformers import pipeline, AutoTokenizer, LlamaForCausalLM
import torch
model_id = "Ericu950/Papy_1_Llama-3.1-8B-Instruct_date"
model = LlamaForCausalLM.from_pretrained(
    model_id,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained(model_id)
generation_pipeline = pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    device_map="auto",
)

2. Run inference on a papyrus fragment of your choice

python

Usage on free tier in Google Colab

If you don’t have access to a larger GPU but want to try the model out, you can run it in a quantized format in Google Colab. The quality of the responses might deteriorate significantly. Follow these steps:

Step 1: Connect to free GPU

Click Connect arrow_drop_down near the top right of the notebook.
Select Change runtime type.
In the modal window, select T4 GPU as your hardware accelerator.
Click Save.
Click the Connect button to connect to your runtime. After some time, the button will present a green checkmark, along with RAM and disk usage graphs. This indicates that a server has successfully been created with your required hardware.

Step 2: Install Dependencies

python

!pip install -U bitsandbytes
import os
os._exit(00)

Step 3: Download and quantize the model

python

from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig, pipeline
import torch
quant_config = BitsAndBytesConfig(
   load_in_4bit=True,
   bnb_4bit_quant_type="nf4",
   bnb_4bit_use_double_quant=True,
   bnb_4bit_compute_dtype=torch.bfloat16
)
model = AutoModelForCausalLM.from_pretrained("Ericu950/Papy_1_Llama-3.1-8B-Instruct_date",
device_map = "auto", quantization_config = quant_config)
tokenizer = AutoTokenizer.from_pretrained("Ericu950/Papy_1_Llama-3.1-8B-Instruct_date")
generation_pipeline = pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    device_map="auto",
)
