4. Quick Start(AX650)#
本章节适用于以下平台:
AX650A
AX650N
AX8850
M76H
本章节介绍 ONNX 模型转换的基本操作, 使用 pulsar2 工具将 ONNX 模型编译成 axmodel 模型. 请先参考 《开发环境准备》 章节完成开发环境搭建.
本节示例模型为开源模型 MobileNetv2.
4.1. Pulsar2 工具链命令说明#
Pulsar2 工具链中的功能指令以 pulsar2 开头, 与用户强相关的命令为 pulsar2 build , pulsar2 run 以及 pulsar2 version.
pulsar2 build用于将onnx模型转换为axmodel格式模型pulsar2 run用于模型转换后的仿真运行pulsar2 version可以用于查看当前工具链的版本信息, 通常在反馈问题时需要提供此信息
root@xxx:/data# pulsar2 --help
usage: pulsar2 [-h] {version,build,run} ...
positional arguments:
{version,build,run}
optional arguments:
-h, --help show this help message and exit
4.2. 模型编译配置文件说明#
/data/config/ 路径下的 mobilenet_v2_build_config.json 展示:
{
"model_type": "ONNX",
"npu_mode": "NPU1",
"quant": {
"input_configs": [
{
"tensor_name": "input",
"calibration_dataset": "./dataset/imagenet-32-images.tar",
"calibration_size": 32,
// 校验数据集归一化的各通道均值, 通道顺序与 tensor_format 一致
"calibration_mean": [103.939, 116.779, 123.68],
// 校验数据集归一化的各通道标准差
"calibration_std": [58.0, 58.0, 58.0]
}
],
"calibration_method": "MinMax",
"precision_analysis": false
},
"input_processors": [
{
"tensor_name": "input",
"tensor_format": "BGR",
// 运行时输入格式
"src_format": "BGR",
// 运行时数据类型
"src_dtype": "U8",
// 运行时数据布局格式
"src_layout": "NHWC",
// 颜色空间转换
"csc_mode": "NoCSC"
}
],
"compiler": {
"check": 0
}
}
注意
input_processors, output_processors 及 quant 节点下 input_configs 中的 tensor_name 字段需要根据模型的实际输入/输出节点名称进行设置,也可以设置为 DEFAULT 代表当前配置应用于全部输入或者输出。
更加详细的内容,请参考 《配置文件详细说明》.
4.3. 编译执行#
以 mobilenetv2-sim.onnx 为例, 执行如下 pulsar2 build 命令编译生成 compiled.axmodel:
pulsar2 build --target_hardware AX650 --input model/mobilenetv2-sim.onnx --output_dir output --config config/mobilenet_v2_build_config.json
警告
在编译模型前,需要确保已经对原始模型使用过 onnxsim 工具优化,主要目的是将模型转变成更利于 Pulsar2 编译的静态图及获得更好的推理性能。有以下两种方法:
在
Pulsar2docker 内部直接执行命令:onnxsim in.onnx out.onnx。使用
pulsar2 build进行模型转换时,增加参数:--onnx_opt.enable_onnxsim true(默认值为 false)。
如果想要进一步了解 onnxsim ,可访问 官方网站 。

4.4. 仿真运行#
本章节介绍 axmodel 仿真运行的基本操作, 使用 pulsar2 run 命令可以直接在 PC 上直接运行由 pulsar2 build 生成的 axmodel 模型,无需上板运行即可快速得到网络模型的运行结果。
4.4.1. 仿真运行准备#
某些模型只能支持特定的输入数据格式,模型的输出数据也是以模组特定的格式输出的。在模型仿真运行前,需要把输入数据转换成模型支持的数据格式,这部分数据操作称为 前处理 。在模型仿真运行后,需要把输出数据转换成工具可以分析查看的数据格式,这部分数据操作称为 后处理 。仿真运行时需要的 前处理 和 后处理 工具已包含在 pulsar2-run-helper 文件夹中。
pulsar2-run-helper 文件夹内容如下所示:

root@xxx:/data# cp output/compiled.axmodel pulsar2-run-helper/models/mobilenetv2.axmodel
4.4.2.1. 输入数据准备#
进入 pulsar2-run-helper 目录,使用 cli_classification.py 脚本将 cat.jpg 处理成 mobilenetv2.axmodel 所需要的输入数据格式。
root@xxx:~/data# cd pulsar2-run-helper

4.5. 开发板运行#
本章节介绍如何在 AX650 M76H 开发板上运行通过 《编译执行》 章节获取 compiled.axmodel 模型.
4.5.1. 开发板获取#
通过企业途径向 AXera 签署 NDA 后获取 AX650 或 M76H EVB.
4.5.2. 使用 ax_run_model 工具快速测试模型推理速度#
为了方便用户测评模型,在开发板上预制了 ax_run_model 工具,此工具有若干参数,可以很方便地测试模型速度和精度。
将 mobilennetv2.axmodel 拷贝到开发板上,执行以下命令即可快速测试模型推理性能(首先推理 3 次进行预热,以排除资源初始化导致的统计误差,然后推理 10 次,统计平均推理速度)。
/root # ax_run_model -m mobilenetv2.axmodel -w 3 -r 10
Run AxModel:
model: mobilenetv2.axmodel
type: 1 Core

min = 0.719 ms max = 0.726 ms avg = 0.721 ms

4.5.3. 使用 sample_npu_classification 示例测试单张图片推理结果#
提示
该运行示例已经预装在开发板的文件系统中,其源文件位于 SDK 的 msp/sample/npu 路径下文件夹下。将 mobilennetv2.axmodel 拷贝到开发板上,使用 sample_npu_classification 进行测试。
sample_npu_classification 输入参数说明:
/root # sample_npu_classification --help
usage: sample_npu_classification --model=string --image=string [options] ...
options:
-m, --model joint file(a.k.a. joint model) (string)
-i, --image image file (string)
-g, --size input_h, input_w (string [=224,224])
-r, --repeat repeat count (int [=1])
-?, --help print this message
通过执行 sample_npu_classification 程序实现分类模型板上运行, 运行结果如下:
/root # sample_npu_classification -m mobilenetv2.axmodel -i /opt/data/npu/images/cat.jpg -r 10
--------------------------------------
