昇腾910b部署Chatglm3-6b进行流式输出【pytorch框架】NPU推理

准备阶段

• 配套软件包Ascend-cann-toolkit和Ascend-cann-nnae
• 适配昇腾的Pytorch
• 适配昇腾的Torchvision Adapter
• 下载ChatGLM3代码
• 下载chatglm3-6b模型，或在modelscope里下载

避坑阶段

• 每个人的服务器都不一样，在ChatGLM3/issues中别人只需要修改指定驱动，但是我的不行
  
• 删除模型文件包中的model.safetensors.index.json，否则加载模型时会自动加载safetensors文件，而不加载bin文件

添加代码

找到ChatGLM3/basic_demo/cli_demo.py

添加以下代码：

import torch
import torch_npu
import torchvision 
import torchvision_npu
from torch_npu.contrib import transfer_to_npu
import os
import platform
import time
torch_device = "npu:3" # 0~7
torch.npu.set_device(torch.device(torch_device))
torch.npu.set_compile_mode(jit_compile=False)
option = {}
option["NPU_FUZZY_COMPILE_BLACKLIST"] = "Tril"
torch.npu.set_option(option)
print("torch && torch_npu import successfully")

模型加载部分修改为：

model = AutoModel.from_pretrained(MODEL_PATH, trust_remote_code=True).npu().eval()
