# InterLM2-Chat NF4 Quant

## Usage

As of 2024/1/17, Transformers must be installed from source and bitsandbytes >=0.42.0 is required in order to load serialized 4-bit quants.

```bash
pip install -U git+https://github.com/huggingface/transformers bitsandbytes
```

## Quantization config

```python
quantization_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_use_double_quant=True,
    bnb_4bit_compute_dtype=torch.bfloat16,
)
```

Not necessary for inference, just load the model without specifying any quantization/`load_in_*bit`.
