# 创建新的conda虚拟环境(可选)
conda create -n npu python=3.10.12 -y
conda activate npu
# 设置pip全局镜像 (可选,加速下载)
pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/
# 安装ms-swift(当前推荐从源码安装, 待发版后可直接pip安装)
git clone https://github.com/modelscope/swift.git
cd swift
pip install -e '.[llm]'
# 安装torch-npu
pip install torch-npu
# 如果你想要使用deepspeed(控制显存占用,训练速度会有一定下降)
pip install deepspeed -U
# datasets==2.19.0不向下兼容,需指定安装2.18.0版本
pip install datasets==2.18.0
# 安装依赖缺失的包
pip install decorator
# 环境对齐 (可选,通常不需要运行. 如果你运行错误, 可以跑下面的代码, 仓库使用最新环境测试)
pip install -r requirements/framework.txt -U
pip install -r requirements/llm.txt -U
测试环境是否安装正确,NPU能否被正常加载：
from transformers.utils import is_torch_npu_available
import torch
import torch_npu
torch.randn((10,), device='npu:0')
torch.npu.set_device(0)
print(is_torch_npu_available()) # True
print(torch.npu.device_count()) # 8查看NPU的P2P连接,这里看到每个NPU都通过7条HCCS与其他NPU互联
