3403(3519Dv500)算子精度比对工具标杆数据生成环境搭建指导（Caffe）

一、简介

        海思平台算子精度比对工具所依赖的标杆数据生成环境搭建指导文档，基于ubuntu操作系统，目前仅支持 Caffe 。

二、环境准备

        1.caffe安装

        参考：

         2. caffe 推理场景dump脚本使用方法

     （1）功能说明

                用于获取caffe的运行结果，可以获取每一层的结果，输入需要是bin文件。

                示例1：dump模型每个节点的npy结果文件

python3.7 caffe_dump.py -m resnet50.prototxt -w resnet50.caffemodel -i test.bin -n 'data' -o ./output_d

        其中 -n 指定的名称为模型的实际输入名称，-i 指定的输入文件需要与输入名称一一对应，且大小以及数据类型相匹配。

示例1：npy格式的dump文件会生成到 -o 指定的路径中，如下图：
