昇腾910b部署qwen-7b-chat进行流式输出【pytorch框架】NPU推理_昇腾部署qwen

准备阶段

参考我上一篇文章910b上跑Chatglm3-6b进行流式输出【pytorch框架】

避坑阶段

• 我在mindspore框架下运行了qwen-7b-base、qwen-7b-chat输出都有大大的问题，参考官方文档

qwen-7b-base的输出

qwen-7b-chat的输出

• 像之前给ChatCLM3一样添加代码，会报错 'torch_npu._C._NPUDeviceProperties' object has no attribute 'major'

解决这个报错能搜到是下面这些

华为官网上的回答，一般都在和稀泥，要么没人理

gitee这个，虽然报错结果一样，但是过程不一样，没有参考价值

Github上看了，推理都是在mindspore框架下进行的，没有参考价值

解决方案

一、modeling_qwen.py

找到第38，39行，替换为

SUPPORT_BF16 = False
SUPPORT_FP16 = True

尝试过SUPPORT_BF16 = True，会报错

二、cli_demo.py

注释加载模型的resume_download

model = AutoModelForCausalLM.from_pretrained(
    args.checkpoint_path,
    device_map=device_map,
    trust_remote_code=True,
    # resume_download=True,
).npu().eval()

结果展示

• 速度很慢，比mindspore慢了一倍，但是好歹能正常输出了，虽然还输出错了。
• 搞笑的是mindspore框架推理ChatGLM3背诵出师表只背诵前半部分，Qwen这里背诵了后半部分，Torch框架下ChatGLM3可以背出全文。
