Instructions to use Nafnaf1k/gpt2-closedbook-qa with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Nafnaf1k/gpt2-closedbook-qa with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Nafnaf1k/gpt2-closedbook-qa", trust_remote_code=True)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Nafnaf1k/gpt2-closedbook-qa", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("Nafnaf1k/gpt2-closedbook-qa", trust_remote_code=True, device_map="auto")
