| To boost inference speed even further, use the ExLlamaV2 kernels by configuring the exllama_config parameter: | |
| import torch | |
| from transformers import AutoModelForCausalLM, GPTQConfig | |
| gptq_config = GPTQConfig(bits=4, exllama_config={"version":2}) | |
| model = AutoModelForCausalLM.from_pretrained("{your_username}/opt-125m-gptq", device_map="auto", quantization_config=gptq_config) | |
| Only 4-bit models are supported, and we recommend deactivating the ExLlama kernels if you're finetuning a quantized model with PEFT. |
