Llama 2 13B Vanilla

This is the Llama 2 13B model fine-tuned as the vanilla (unmodified) baseline, trained and evaluated in the paper ASIDE: Architectural Separation of Instructions and Data in Language Models.

Model Description

This is the vanilla (unmodified) baseline fine-tuned with the same training data and procedure, but without any embedding modification.

Usage

To use this model, first clone and follow the installation instructions in the official ASIDE Repository.

Inside the repository, run the following code snippet (also provided here as a script) to do inference with this model.

import torch
import deepspeed
import json
import os
from huggingface_hub import login

from model_api import CustomModelHandler  # Import your custom handler
from model_api import format_prompt  # Import your prompt formatting function

# Define your instruction and data
instruction_text = "Translate to German."
data_text = "Who is Albert Einstein?"

# Model configuration
hf_token = os.environ["HUGGINGFACE_HUB_TOKEN"]
login(token=hf_token)
embedding_type = "single_emb"  
base_model = "meta-llama/Llama-2-13b-hf"
model_path = "Embeddings-Collab/llama_2_13b_single_emb_emb_SFTv110_from_base_run_20"

# Initialize the model handler
handler = CustomModelHandler(
    model_path, 
    base_model, 
    base_model, 
    model_path, 
    None,
    0, 
    embedding_type=embedding_type, 
    load_from_checkpoint=True
)

# Initialize DeepSpeed inference engine
engine = deepspeed.init_inference(
    model=handler.model,
    mp_size=torch.cuda.device_count(),  # Number of GPUs
    dtype=torch.float16,
    replace_method='auto',
    replace_with_kernel_inject=False
)
handler.model = engine.module

# Load prompt templates
with open("./data/prompt_templates.json", "r") as f:
    templates = json.load(f)

template = templates[0]  
instruction_text = format_prompt(instruction_text, template, "system")
data_text = format_prompt(data_text, template, "user")

# Generate output
output, inp = handler.call_model_api_batch([instruction_text], [data_text])
print(output)
