I used the code from "/GPTQModel/examples/quantization/basic_usage_autoround.py" to quantize deepseek-ai/DeepSeek-R1-Distill-Llama-8B and Qwen/QwQ-32B, but I encountered the same issue in both cases.

Thank you!!!!!!!!!!!!!!!!

[Qubitium]

@davidray222 Thanks for the report. I think your torch version 2.2 maybe too old. Or maybe I broke something in main. Will check soon!

[Qubitium]

@davidray222 I think you have a broken Numy pkg install. Try the following:

import torch

t = torch.tensor([1, 2, 3], dtype=torch.int32)
print(t.numpy())

Run the above python code in your env. If you get same error, I suggest you uninstall numpy and re-install numpy.

[Qubitium]

@davidray222 Also please use releae-version 2.0 if possible. There may be other bugs in the main/devel branch. There are some changes on main that have not been ci validated.

@Qubitium
I successfully quantized DeepSeek-R1-Distill-Llama-8B into a 4-bit model, but I encountered an issue where, no matter what input I provide, the output is always "!!!!!!!!". Could this be due to a mistake in my process, or is it related to an issue with my environment or version compatibility?

I update Software version:

CUDA Version: 12.8

Show output of:

Name: gptqmodel
Version: 2.0.0
---
Name: torch
Version: 2.4.0
---
Name: transformers
Version: 4.49.0
---
Name: accelerate
Version: 1.3.0
---
Name: triton
Version: 3.0.0
---
Name: numpy
Version:2.2.2

my steps:
1.
I used the code from "/GPTQModel/examples/quantization/basic_usage_autoround.py" to quantize deepseek-ai/DeepSeek-R1-Distill-Llama-8B.
2.
I got these files

I use this code:
export GPTQMODEL_USE_MODELSCOPE=True

from gptqmodel import GPTQModel
# load Qwen/Qwen2.5-0.5B-Instruct-GPTQ-Int4 from modelscope
model = GPTQModel.load("/mnt/8tb_raid/david_model/GPTQModel/examples/quantization/autoround/DeepSeek-R1-Distill-Llama-8B-4bit-32g/")
result = model.generate("hello")[0] # tokens
print(model.tokenizer.decode(result)) # string output

get the output always is

I would like to ask if I made a mistake somewhere.Thank you!!
