Libraries

How to use lora-x/backpack-gpt2 with Transformers:

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

pipe = pipeline("text-generation", model="lora-x/backpack-gpt2", trust_remote_code=True)

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

tokenizer = AutoTokenizer.from_pretrained("lora-x/backpack-gpt2", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("lora-x/backpack-gpt2", trust_remote_code=True, device_map="auto")
