# 多硬件安装飞桨
|
|
|
|
本文档主要针对昇腾 NPU 硬件平台，介绍如何安装飞桨。
|
|
|
|
## 1. 昇腾 NPU 飞桨安装
|
|
|
|
### 1.1 环境准备
|
|
|
|
当前 PaddleOCR 支持昇腾 910B 芯片，昇腾驱动版本为 23.0.3。考虑到环境差异性，我们推荐使用飞桨官方提供的标准镜像完成环境准备。
|
|
|
|
#### 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.RC1。
|
|
|
|
```bash linenums="1"
|
|
# 适用于 X86 架构，暂时不提供 Arch64 架构镜像
|
|
docker pull registry.baidubce.com/device/paddle-npu:cann80RC1-ubuntu20-x86_64-gcc84-py39
|
|
```
|
|
|
|
#### 启动容器
|
|
|
|
ASCEND_RT_VISIBLE_DEVICES 指定可见的 NPU 卡号
|
|
|
|
```bash linenums="1"
|
|
docker run -it --name paddle-npu-dev -v $(pwd):/work \
|
|
--privileged --network=host --shm-size=128G -w=/work \
|
|
-v /usr/local/Ascend/driver:/usr/local/Ascend/driver \
|
|
-v /usr/local/bin/npu-smi:/usr/local/bin/npu-smi \
|
|
-v /usr/local/dcmi:/usr/local/dcmi \
|
|
-e ASCEND_RT_VISIBLE_DEVICES="0,1,2,3,4,5,6,7" \
|
|
registry.baidubce.com/device/paddle-npu:cann80RC1-ubuntu20-x86_64-gcc84-py39 /bin/bash
|
|
```
|
|
|
|
### 1.2 安装 paddle 包
|
|
|
|
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。
|
|
|
|
#### 1. 下载安装 Python3.9 的 wheel 安装包
|
|
|
|
```bash linenums="1"
|
|
# 注意需要先安装飞桨 cpu 版本
|
|
pip install https://paddle-model-ecology.bj.bcebos.com/paddlex/whl/paddle-device/npu/paddlepaddle-0.0.0-cp39-cp39-linux_x86_64.whl
|
|
pip install https://paddle-model-ecology.bj.bcebos.com/paddlex/whl/paddle-device/npu/paddle_custom_npu-0.0.0-cp39-cp39-linux_x86_64.whl
|
|
```
|
|
|
|
#### 2. 验证安装包
|
|
|
|
安装完成之后，运行如下命令。
|
|
|
|
```bash linenums="1"
|
|
python -c "import paddle; paddle.utils.run_check()"
|
|
```
|
|
|
|
预期得到如下输出结果
|
|
|
|
```bash linenums="1"
|
|
Running verify PaddlePaddle program ...
|
|
PaddlePaddle works well on 1 npu.
|
|
PaddlePaddle works well on 8 npus.
|
|
PaddlePaddle is installed successfully! Let's start deep learning with PaddlePaddle now.
