π Example: Using LLaMA with Hugging Face Transformers in Python
from transformers import LlamaTokenizer, LlamaForCausalLM
# Load tokenizer and model (example: 7B model)
tokenizer = LlamaTokenizer.from_pretrained("meta-llama/Llama-2-7b")
model = LlamaForCausalLM.from_pretrained("meta-llama/Llama-2-7b")
# Encode input text
input_text = "Explain the benefits of LLaMA in NLP research."
inputs = tokenizer(input_text, return_tensors="pt")
# Generate output
outputs = model.generate(**inputs, max_length=100)
generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(generated_text)
