### 11. How to run w8a8 DeepSeek model?
Currently, running on v0.7.3, we should run w8a8 with vllm + vllm-ascend + mindie-turbo. And we only need vllm + vllm-ascend when v0.8.X is released. After installing the above packages, you can follow the steps below to run w8a8 DeepSeek:
Currently, w8a8 DeepSeek is working in process: [support AscendW8A8 quantization](https://github.com/vllm-project/vllm-ascend/pull/511)
1. Quantize bf16 DeepSeek, e.g. [unsloth/DeepSeek-R1-BF16](https://modelscope.cn/models/unsloth/DeepSeek-R1-BF16), with msModelSlim to get w8a8 DeepSeek. Find more details in [msModelSlim doc](https://gitee.com/ascend/msit/tree/master/msmodelslim/msmodelslim/pytorch/llm_ptq)
2. Copy the content of `quant_model_description_w8a8_dynamic.json` into the `quantization_config` of `config.json` of the quantized model files.
3. Reference with the quantized DeepSeek model.
Please run DeepSeek with BF16 now, follwing the [Multi-Node DeepSeek inferencing tutorail](https://vllm-ascend.readthedocs.io/en/main/tutorials/multi_node.html)
### 12. There is not output in log when loading models using vllm-ascend, How to solve it?
