🐛 Describe the bug

I use auto_fp8 to quantize the model internlm/internlm2-chat-7b.

from transformers import AutoTokenizer
from auto_fp8 import AutoFP8ForCausalLM, BaseQuantizeConfig

pretrained_model_dir = "internlm/internlm2-chat-7b"
quantized_model_dir = "model/internlm2-chat-7b_hf_fp8"

# Define quantization config with static activation scales

tokenizer = AutoTokenizer.from_pretrained(pretrained_model_dir, use_fast=True)
examples = ["auto_fp8 is an easy-to-use model quantization library"]
examples = tokenizer(examples, return_tensors="pt").to("cuda")

quantize_config = BaseQuantizeConfig(quant_method="fp8", activation_scheme="dynamic")

# Load the model, quantize, and save checkpoint
model = AutoFP8ForCausalLM.from_pretrained(pretrained_model_dir, quantize_config, trust_remote_code=True)
model.quantize(examples)
model.save_quantized(quantized_model_dir)

Then I would like to load the fp8 model, but got error.

from vllm import LLM, SamplingParams

prompts = [
    "Hello, my name is",
    "The president of the United States is",
    "The capital of France is",
    "The future of AI is",
]
sampling_params = SamplingParams(temperature=0.8, top_p=0.95)

llm_fp8 = LLM(model="model/internlm2-chat-7b_hf_fp8/", trust_remote_code=True)
outputs = llm_fp8.generate(prompts, sampling_params)

# Print the outputs.
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")

error is

[artetaout]

does "GPU 0: A100-SXM-80GB" support FP8 ?

does "GPU 0: A100-SXM-80GB" support FP8 ?

yes, I used auto-fp8 to quantize models such as internlm-chat-7b and facebook/opt-125m and loaded the quantized models. They can work.

[robertgshaw2-neuralmagic]

Can you post the model to the hf hub so I can take a look?
