For demonstration, please refer to demo.jpynb in the files.
To use the checkpoint:
```
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM
config = PeftConfig.from_pretrained("TorpilleAlpha/scanpy-llama")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-7b-chat-hf")# or use your local llama-2-7B-chat shards
model = PeftModel.from_pretrained(model, "TorpilleAlpha/scanpy-llama")
```
