How to Get Started with the Model
from transformers import LlamaTokenizer, LlamaForCausalLM
import torch
tokenizer = LlamaTokenizer.from_pretrained("Xianjun/Quokka-7b-instruct ")
model = LlamaForCausalLM.from_pretrained("Xianjun/Quokka-7b-instruct ").half().to("cuda")
instruction = "How to ..."
batch = tokenizer(instruction, return_tensors="pt", add_special_tokens=False).to("cuda")
with torch.no_grad():
output = model.generate(**batch, max_new_tokens=512, temperature=0.7, do_sample=True)
response = tokenizer.decode(output[0], skip_special_tokens=True)
