# PaddleClas 昇腾 Python部署示例
|
|
|
|
|
|
本目录下提供`infer.py`快速完成PaddleClas在昇腾AI处理器上部署的示例.
|
|
|
|
|
|
|
|
|
|
|
|
## 1. 部署环境准备
|
|
|
|
|
|
在部署前，需自行编译基于昇腾AI处理器的FastDeploy python wheel包并安装，参考文档，参考文档[昇腾AI处理器部署环境编译](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#自行编译安装)
|
|
|
|
|
|
|
|
|
|
|
|
## 2. 部署模型准备
|
|
|
|
|
|
在部署前, 请准备好您所需要运行的推理模型, 您可以在[FastDeploy支持的PaddleClas模型列表](../README.md)中下载所需模型.
|
|
|
|
|
|
|
|
|
|
|
|
## 3. 运行部署示例
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# 安装FastDpeloy 昇腾预测库 python包（详细文档请参考`部署环境准备`）
|
|
|
|
|
|
|
|
|
|
|
|
# 下载部署示例代码

|
|
|
|
git clone https://github.com/PaddlePaddle/FastDeploy.git
|
|
|
|
|
|
cd FastDeploy/examples/vision/classification/paddleclas/ascend/python
|
|
|
|
|
|
|
|
|
|
|
|
# 如果您希望从PaddleClas下载示例代码，请运行
|

|
|
|
|
git clone https://github.com/PaddlePaddle/PaddleClas.git
|

|
|
|
|
# 注意：如果当前分支找不到下面的fastdeploy测试代码，请切换到develop分支
|
|
|
|
|
|
git checkout develop
|
2023-03-15 21:12:51 +08:00
|
|
|
|
cd PaddleClas/deploy/fastdeploy/ascend/python
|
|
|
|
|
|
|
|
|
|
|
|
# 下载ResNet50_vd模型文件和测试图片
|
|
|
|
|
|
wget https://bj.bcebos.com/paddlehub/fastdeploy/ResNet50_vd_infer.tgz
|
|
|
|
|
|
tar -xvf ResNet50_vd_infer.tgz
|
|
|
|
|
|
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
|
|
|
|
|
|
|
|
|
|
|
|
# 在Ascend AI 处理器上推理
|
|
|
|
|
|
python infer.py --model ResNet50_vd_infer --image ILSVRC2012_val_00000010.jpeg --topk 1
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
运行完成后返回结果如下所示
|
|
|
|
|
|
```bash
|
|
|
|
|
|
ClassifyResult(
|
|
|
|
|
|
label_ids: 153,
|
|
|
|
|
|
scores: 0.686229,
|
