## 1、docker环境准备
* 拉取镜像，此镜像仅为开发环境，镜像中不包含预编译的飞桨安装包，镜像中已经默认安装了昇腾算子库 CANN-8.0.T13。
```
```bash
# 适用于 X86 架构
docker pull registry.baidubce.com/device/paddle-npu:cann80T13-ubuntu20-x86_64-gcc84-py39
# 适用于 Aarch64 架构
docker pull registry.baidubce.com/device/paddle-npu:cann80T13-ubuntu20-aarch64-gcc84-py39

当前提供 Python3.9 的 wheel 安装包。如有其他 Python 版本需求，可以参考[飞桨官方文档](https://www.paddlepaddle.org.cn/install/quick)自行编译安装。

* 下载安装 Python3.9 的 wheel 安装包
```
```bash
# 注意需要先安装飞桨 cpu 版本
python3.9 -m pip install paddlepaddle==3.0.0.dev20240520 -i https://www.paddlepaddle.org.cn/packages/nightly/cpu/
python3.9 -m pip install paddle_custom_npu==3.0.0.dev20240719 -i https://www.paddlepaddle.org.cn/packages/nightly/npu/

* 验证安装包安装完成之后，运行如下命令
* arm机器上需要设置环境变量（x86环境无需设置）
```bash
# 解决libgomp在arm机器上报错
# "libgomp cannot allocate memory in static TLS block"
export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libgomp.so.1:$LD_PRELOAD
