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==2.1.0

    x86:

    pip3 install torch==2.1.0+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 Python3.8 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 Python3.8 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==2.1.0.post17

    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版本遵循如下约束。

  • ARM架构下推荐使用gcc 10.2版本
  • X86架构下推荐使用gcc 9.3.1

  1. 克隆torch_npu代码仓

    git clone https://gitcode.com/ascend/pytorch.git -b v2.1.0-7.2.0 --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 3.8 为例。

    cd /home/pytorch
bash ci/build.sh --python=3.8

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 11.2.1。

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=16

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。

分支维护策略

Ascend Extension for PyTorch版本分支的维护阶段如下：

状态 时间 说明
计划 1—3 个月 计划特性
开发 6—12 个月 开发新特性并修复问题，定期发布新版本。针对不同的PyTorch版本采取不同的策略，常规分支的开发周期分别为6个月，长期支持分支的开发周期为12个月
维护 1年/3.5年 常规分支维护1年,长期支持分支维护3.5年。对重大BUG进行修复，不合入新特性，并视BUG的影响发布补丁版本
生命周期终止（EOL） N/A 分支不再接受任何修改
