Inference

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_id = "minghaowu/phi-2-OpenHermes-2.5"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="auto")
pipe = pipeline("text-generation", model=model, tokenizer=tokenizer, device_map="auto")

your_instruction = <your_instruction>
infer_prompt = f"### USER: {your_instruction} <|endoftext|>\n### ASSISTANT:"
output = pipe(infer_prompt, do_sample=True, max_new_tokens=256)[0]["generated_text"]
print(output)
