The Swallow model, a marvel of recent artificial intelligence breakthroughs, enhances the Japanese language capabilities of the Llama 2 family through continual pre-training and supervised fine-tuning. In this guide, we’ll walk you through the steps to use the Swallow model effectively, discuss its recent updates, and troubleshoot common issues. Let’s dive in!
Understanding the Swallow Model
Before we jump to the usage, let’s visualize how the Swallow model functions. Imagine it as a chef in a kitchen—a kitchen where Japanese ingredients (data) are masterfully mixed to create unique dishes (text outputs). The chef was trained not only on Japanese cuisine but also incorporates flavors from English (multi-language capabilities). With each new recipe (model update), the chef refines their skills, introducing more complex and flavorful dishes (enhanced outputs) for discerning customers (users).
Latest Model Releases
Here’s a brief schedule of the latest updates and releases related to the Swallow models:
- April 26, 2024: Released version 0.1 of the instruction-tuned models, including:
- March 2, 2024: Released the Swallow-7b-plus-hf model, trained with approximately twice as many Japanese tokens as the Swallow-7b-hf.
- February 4, 2024: Released the Swallow-13b-NVE-hf.
- January 26, 2024: Introduced several new models focused on instruction, including Swallow-7b-NVE-instruct-hf.
- December 19, 2023: Launched multiple versions like Swallow-7b-hf and others.
How to Use the Swallow Model
To harness the power of the Swallow model, you’ll need to follow these steps:
Step 1: Install Dependencies
First, install the necessary dependencies listed in the requirements.txt file:
pip install -r requirements.txtStep 2: Setup the Instruct Model
Use the following template to construct a prompt for the Instruct model:
s[INST] SYSnSYSTEM_PROMPTnSYSnnUSER_MESSAGE_1 [INST] BOT_MESSAGE_1s[INST] USER_MESSAGE_2 [INST]Step 3: Implement the Model
Here is a sample Python code snippet showing how to set up and use the Swallow model:
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_name = "tokyotech-llm/Swallow-70b-instruct-v0.1"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)
device = "cuda"
messages = [
{"role": "system", "content": "あなたは誠実で優秀な日本人のアシスタントです。"},
{"role": "user", "content": "東京工業大学の主なキャンパスについて教えてください"}
]
encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt")
model_inputs = encodeds.to(device)
model.to(device)
generated_ids = model.generate(model_inputs, max_new_tokens=128, do_sample=True)
decoded = tokenizer.batch_decode(generated_ids)
print(decoded[0])Troubleshooting Common Issues
While working with models like Swallow, you may face some challenges. Here are some common issues and solutions:
- Model Not Loading: Ensure that all dependencies are correctly installed, and you’re using the correct syntax to load the model.
- Unexpected Outputs: Check if the prompt format strictly adheres to the specified syntax; otherwise, the model may generate subpar responses.
- Performance Issues: If the model runs slow, make sure you are using a device capable of handling extensive computations (e.g., a robust GPU).
