## Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
from accelerate import infer_auto_device_map, dispatch_model
from accelerate.utils import get_balanced_memory

tokenizer = AutoTokenizer.from_pretrained("TigerResearch/tigerbot-7b-sft-v2")

model = AutoModelForCausalLM.from_pretrained("TigerResearch/tigerbot-7b-sft-v2")

max_memory = get_balanced_memory(model)
device_map = infer_auto_device_map(model, max_memory=max_memory, no_split_module_classes=["BloomBlock"])
model = dispatch_model(model, device_map=device_map, offload_buffers=True)

device = torch.cuda.current_device()


tok_ins = "\n\n### Instruction:\n"
tok_res = "\n\n### Response:\n"
prompt_input = tok_ins + "{instruction}" + tok_res

input_text = "What is the next number after this list: [1, 2, 3, 5, 8, 13, 21]"
input_text = prompt_input.format_map({'instruction': input_text})

max_input_length = 512
max_generate_length = 1024
generation_kwargs = {
        "top_p": 0.95,
        "temperature": 0.8,
        "max_length": max_generate_length,
        "eos_token_id": tokenizer.eos_token_id,
        "pad_token_id": tokenizer.pad_token_id,
        "early_stopping": True,
        "no_repeat_ngram_size": 4,
    }

inputs = tokenizer(input_text, return_tensors='pt', truncation=True, max_length=max_input_length)
