You Should Know:
Working with LLMs (Practical Commands)
- Use Hugging Face Transformers to load an LLM:
from transformers import pipeline generator = pipeline('text-generation', model='gpt2') print(generator("Explain AI in simple terms:"))
Fine-tuning Models
- Fine-tune a model using PyTorch:
from transformers import GPT2LMHeadModel, GPT2Tokenizer tokenizer = GPT2Tokenizer.from_pretrained('gpt2') model = GPT2LMHeadModel.from_pretrained('gpt2') Train with custom dataset
Handling Tokens
- Count tokens in a text:
tokens = tokenizer.encode("Hello, AI world!", return_tensors="pt") print(len(tokens[0]))
Retrieval-Augmented Generation (RAG)
- Implement RAG with FAISS for similarity search:
from transformers import RagTokenizer, RagRetriever tokenizer = RagTokenizer.from_pretrained("facebook/rag-token-base") retriever = RagRetriever.from_pretrained("facebook/rag-token-base")
Preventing Hallucinations
- Use temperature=0 for deterministic outputs:
output = generator("What is quantum computing?", temperature=0)
Linux Commands for AI Workflows
- Monitor GPU usage (for training models):
nvidia-smi
- Process large datasets efficiently:
awk '{print $1}' dataset.txt | sort | uniq -c
Windows AI Development
- Check CUDA version (for PyTorch/TensorFlow):
nvcc --version
What Undercode Say
