快速入门

基于CNN模型识别手写数字的脚本，对在GPU上训练的该脚本代码进行修改，使其可以迁移到昇腾NPU上进行训练。具体操作请参见Ascend Extension for PyTorch 快速入门。

环境部署

使用二进制文件进行安装

我们为用户提供可以快速安装torch_npu的whl安装包。在安装torch_npu之前，您需要先安装CANN软件。昇腾辅助软件中有更多关于CANN的版本信息。请参考CANN安装指南获取CANN安装包。

  1. 安装PyTorch

    通过 pip 安装 PyTorch。

    aarch64:

    pip3 install torch==2.8.0

    x86:

    pip3 install torch==2.8.0+cpu  --index-url https://download.pytorch.org/whl/cpu

    若使用pip命令安装失败，请使用下载链接或进入PyTorch官方网站进行查询下载对应版本。

    架构 Python版本 下载链接
    x86 Python3.9 下载链接
    x86 Python3.10 下载链接
    x86 Python3.11 下载链接
    aarch64 Python3.9 下载链接
    aarch64 Python3.10 下载链接
    aarch64 Python3.11 下载链接

  2. 安装torch_npu依赖

    运行以下命令安装依赖。

    pip3 install pyyaml
pip3 install setuptools

  3. 安装torch_npu

    pip3 install torch-npu==2.8.0

    如需要保存安装日志，可在pip3 install命令后面加上参数 --log <PATH>，并对您指定的目录<PATH>做好权限管控。

使用源代码进行安装

某些特殊场景下，用户可能需要自行编译torch_npu。可以根据昇腾辅助软件表和PyTorch与Python版本配套表选择合适的分支。

推荐使用Docker镜像编译torch_npu，可以通过以下步骤获取（建议只挂载工作路径，并避开系统路径，以降低安全风险）, 生成的.whl文件路径为./dist/。

须知：
如果不使用镜像，编译时请注意gcc版本遵循约束：ARM与X86架构下推荐使用gcc 13.3。

  1. 克隆torch_npu代码仓

    git clone https://gitcode.com/ascend/pytorch.git -b v2.8.0-7.2.0 --depth 1

  2. 构建镜像

    cd pytorch/ci/docker/{arch} # {arch} for X86 or ARM
docker build -t manylinux-builder:v1 .

  3. 进入Docker容器

    docker run -it -v /{code_path}/pytorch:/home/pytorch manylinux-builder:v1 bash
# {code_path} is the torch_npu source code path

  4. 编译torch_npu

    以Python 3.9 为例。

    cd /home/pytorch
bash ci/build.sh --python=3.9

提示

如果想使用新的C++ ABI编译，请首先运行如下命令，此时推荐和社区torch包相同的编译环境：glibc 2.28, gcc 13.3.1。

export _GLIBCXX_USE_CXX11_ABI=1

同时，我们支持使用如下变量配置-fabi-version，要求和社区torch包ABI版本一致。

export _ABI_VERSION=18

安装后验证

前提

运行以下命令初始化CANN环境变量。

# Default path, change it if needed.
source /usr/local/Ascend/ascend-toolkit/set_env.sh

快速验证

可以通过以下样例快速体验昇腾NPU。

import torch
- import torch_npu # torch_npu2.5.1及以后版本可以不用手动导包

x = torch.randn(2, 2).npu()
y = torch.randn(2, 2).npu()
z = x.mm(y)

print(z)

卸载

Pytorch框架训练环境的卸载可以参考昇腾官方文档。

torch_npu的卸载只需执行命令：

pip3 uninstall torch_npu

如需要保存卸载日志，可在pip3 uninstall命令后面加上参数 --log <PATH>，并对您指定的目录<PATH>做好权限管控。
