REAL Code Examples from the Repository

Example 1: Tokenization and Embeddings

Tokenization and embeddings are fundamental to NLP. Here’s a basic example of tokenization using the Hugging Face Transformers library:

from transformers import AutoTokenizer

# Load pre-trained tokenizer
tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')

# Tokenize input text
text = "Hello, how are you?"
tokens = tokenizer.tokenize(text)
print(tokens)

This code snippet demonstrates how to tokenize a simple input text using a pre-trained BERT tokenizer. The output will be a list of tokens.

Example 2: Fine-Tuning a Pre-trained Model

Fine-tuning a pre-trained model for a specific task is a crucial skill. Here’s an example of fine-tuning a model using the Hugging Face library:

from transformers import AutoModelForSequenceClassification, Trainer, TrainingArguments

# Load pre-trained model
model = AutoModelForSequenceClassification.from_pretrained('bert-base-uncased', num_labels=2)

# Define training arguments
training_args = TrainingArguments(
    output_dir='./results',
    num_train_epochs=3,
    per_device_train_batch_size=16,
    per_device_eval_batch_size=64,
    warmup_steps=500,
    weight_decay=0.01,
)

# Initialize Trainer
trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=train_dataset,
    eval_dataset=eval_dataset,
)

# Train the model
trainer.train()

This example shows how to fine-tune a BERT model for sequence classification. The Trainer class handles the training process, making it easier to manage model training.

Example 3: Deploying an LLM Application

Deploying LLM applications via APIs is a key skill. Here’s an example of deploying a model using Hugging Face’s API:

from huggingface_hub import HfApi

# Initialize Hugging Face API
api = HfApi()

# Deploy model
api.upload_model(
    model_id="my-llm-model",
    model_path="./my_model",
    repo_type="model",
)

This code snippet demonstrates how to upload a trained model to Hugging Face’s model hub, making it accessible via API for deployment.
