Welcome to the world of advanced language models! In this article, we’ll explore how to use the GPT-SW3 models developed by AI Sweden, a collection of transformer language models that supports multiple languages including Swedish, Norwegian, Danish, Icelandic, and English. Whether you’re a seasoned developer or a curious beginner, this guide will provide you with the necessary steps to get started with GPT-SW3.

Getting Access to the Model

Before using the GPT-SW3 models in your Python projects, you need to ensure you have proper access. Follow these steps:

1. Log in to your Hugging Face account using your access token.
2. Use the command huggingface-cli login in your terminal. If you’re unsure about this step, refer to the HuggingFace Quick Start Guide.

Preparing Your Environment

To effectively utilize GPT-SW3, you’ll need the necessary libraries. Make sure you have Python and the following packages installed:

• torch
• transformers

Loading the Model and Tokenizer

Once your environment is ready, you can proceed to load the model and tokenizer. Let’s break it down with a simple analogy:

Imagine the tokenizer as a translator and the model as the brain behind generating responses. Just like a translator breaks down languages into understandable segments for a person to process, the tokenizer converts text into numerical values (tokens) that the model can use to generate coherent responses. Here’s how you can load them:

import torch
from transformers import pipeline, AutoTokenizer, AutoModelForCausalLM

# Initialize Variables
model_name = "AI-Sweden-Models/gpt-sw3-1.3b"
device = "cuda:0" if torch.cuda.is_available() else "cpu"
prompt = "Träd är fina för att"

# Initialize Tokenizer and Model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)
model.eval()
model.to(device)

Generating Text

Once the model and tokenizer are ready, you can start generating text based on your input prompt. Here’s how:

• Using the Generate Method
• input_ids = tokenizer(prompt, return_tensors="pt").to(device)
• generated_token_ids = model.generate(inputs=input_ids, max_new_tokens=100, do_sample=True, temperature=0.6, top_p=1)[0]
• generated_text = tokenizer.decode(generated_token_ids)

This method allows for a more granular approach to text generation where you control several parameters. However, if you want a simpler way to generate text, you can use the HuggingFace pipeline.

# Using HuggingFace Pipeline
generator = pipeline("text-generation", tokenizer=tokenizer, model=model, device=device)
generated = generator(prompt, max_new_tokens=100, do_sample=True, temperature=0.6, top_p=1)[0]["generated_text"]

Troubleshooting Tips

If you encounter any issues during setup or while generating text, here are a few troubleshooting tips:

• Ensure you have installed the necessary packages and that your versions are compatible with your Python installation.
• If you encounter login issues, double-check your Hugging Face access token and ensure you are logged in correctly.
• If the model does not load, verify your internet connection and ensure that the model name is spelled correctly.
• In case of performance issues on your GPU, consider using a simpler model or reduce the max_new_tokens parameter.
