How to Run a Large Language Model on Your Raspberry Pi

If you are interested in natural language processing (NLP) and want to experiment with large language models such as GPT-3 or BERT, you might think that you need a powerful GPU or cloud computing service to run them. However, in this blog post, I will show you how you can run a large language model on your Raspberry Pi, a low-cost and portable computer that can fit in your pocket.

Why would you want to run a large language model on your Raspberry Pi? Well, there are several reasons:

- You can use it for offline NLP tasks, such as text generation, summarization, translation, sentiment analysis, etc., without relying on an internet connection or paying for cloud services.

- You can learn more about how large language models work and how to fine-tune them for your own purposes.

- You can have fun and impress your friends with your own AI-powered projects, such as a chatbot, a voice assistant, a text-based game, etc.

Of course, running a large language model on your Raspberry Pi also comes with some challenges and limitations:

- You will need a Raspberry Pi 4 with at least 4 GB of RAM, a microSD card with at least 32 GB of storage, and a power supply. You will also need a keyboard, a mouse, and a monitor to set up your Raspberry Pi.

- You will need to install some software packages and libraries on your Raspberry Pi, such as TensorFlow Lite, PyTorch, Hugging Face Transformers, etc. This might take some time and patience, as some of them are not officially supported or optimized for the Raspberry Pi platform.

- You will not be able to run the full versions of the large language models, as they are too big and complex for the Raspberry Pi's hardware. Instead, you will have to use smaller and simpler versions of the models, such as DistilBERT or MiniLM, which have fewer parameters and layers but still retain most of the capabilities of the original models.

- You will have to compromise on the speed and quality of the NLP tasks, as the Raspberry Pi's CPU is not as fast or powerful as a GPU or cloud service. You might also encounter some errors or bugs along the way.

So, how do you actually run a large language model on your Raspberry Pi? Here are the main steps:

1. Set up your Raspberry Pi with the latest version of Raspberry Pi OS and update it.

2. Install TensorFlow Lite on your Raspberry Pi following this guide: https://www.tensorflow.org/lite/guide/python

3. Install PyTorch on your Raspberry Pi following this guide: https://qengineering.eu/install-pytorch-on-raspberry-pi-4.html

4. Install Hugging Face Transformers on your Raspberry Pi following this guide: https://huggingface.co/transformers/installation.html

5. Choose a large language model that you want to run on your Raspberry Pi from this list: https://huggingface.co/models

6. Download the model and its tokenizer using the Hugging Face Transformers library. For example, if you want to use DistilBERT for text classification, you can use this code:

python
from transformers import AutoModelForSequenceClassification, AutoTokenizer
model = AutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
tokenizer = AutoTokenizer.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
```

7. Convert the model to TensorFlow Lite format using the Hugging Face Transformers library. For example, if you want to convert DistilBERT for text classification, you can use this code:


```python
from transformers import TFAutoModelForSequenceClassification
tf_model = TFAutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english", from_pt=True)
tf_model.save_pretrained("./distilbert_tf")
converter = tf.lite.TFLiteConverter.from_saved_model("./distilbert_tf")
tflite_model = converter.convert()
open("distilbert.tflite", "wb").write(tflite_model)
```

8. Load the TensorFlow Lite model and its tokenizer on your Raspberry Pi and use them for your NLP task. For example, if you want to use DistilBERT for text classification, you can use this code:


```python
import tensorflow as tf

interpreter = tf.lite.Interpreter(model_path="distilbert.tflite")
interpreter.allocate_tensors()

input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()

text = "This movie is awesome!"
inputs = tokenizer(text, return_tensors="tf")
input_ids = inputs["input_ids"].numpy()
attention_mask = inputs["attention_mask"].numpy()

interpreter.set_tensor(input_details[0]["index"], input_ids)
interpreter.set_tensor(input_details[1]["index"], attention_mask)
interpreter.invoke()

output = interpreter.get_tensor(output_details[0]["index"])
prediction = tf.argmax(output, axis=1).numpy()[0]
label = ["negative", "positive"][prediction]
print(f"Text: {text}")
print(f"Label: {label}")
```


Congratulations! You have successfully run a large language model on your Raspberry Pi. You can now experiment with different models and tasks and see what you can achieve with your Raspberry Pi and NLP. Have fun and happy coding!
