import torch

model_path = "Felladrin/TinyMistral-248M-Chat-v3"
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path).to(device)
streamer = TextStreamer(tokenizer)

    },
    {
        "role": "assistant",
        "content": "Sure! What's it?",
    },
    {
        "role": "user",
        "content": "What are some potential applications for quantum computing?",

    attention_mask=inputs.attention_mask,
    max_length=tokenizer.model_max_length,
    streamer=streamer,
    eos_token_id=tokenizer.eos_token_id,
