[Benchmark tool] Support precision evaluation on Android (using imagenet) by zhaoyang-star · Pull Request #7525 · PaddlePaddle/Paddle-Lite

1. 背景

benchmark_bin 工具可以读取真实的验证集数据，进行计算后，给出性能数据和精度数据。

2012 ILSVRC 验证集共 5K 张图片，约 6GB 存储空间，占用空间比较大，为适应端侧应用场景从中筛选出 1K 张图片进行验证。
筛选方法：从验证集中，每个类别挑选一张图片，最后形成一个含有 1K 张图片的验证集子集。

ILSVRC 2012 image classification task，可在此链接下载。

2. 适用场景

目前基于验证集的精度评测功能仅支持安卓系统，对其它系统的支持在开发中。

3. 在 Android 上运行精度评测

3.1 编译

./lite/tools/build_android.sh --toolchain=clang --with_benchmark=ON full_publish

编译完成后，会生成 build.lite.*./lite/api/benchmark_bin 二进制文件、基于 NDK 预编译好的 OpenCV4.1.0 和验证集。

   build.lite.*./third_party
   ├── opencv4.1.0                              预编译好的 OpenCV
   ├── validation_dataset
   │   ├── ILSVRC2012_1000_cls                  ILSVRC 2012 图片数据
   │   ├── ILSVRC2012_1000_cls_label_list.txt   ILSVRC 2012 标签数据

3.2 运行

需要将如下文件通过 adb 上传至手机：

Paddle 模型（combined 或 uncombined 格式均可）或已经 opt 工具离线优化后的 .nb 文件
二进制文件benchmark_bin
ILSVRC 2012 图片数据
ILSVRC 2012 标签数据
数据集的配置文件 config.txt

在 Host 端机器上操作例子如下：

# 获取模型文件
wget https://paddle-inference-dist.bj.bcebos.com/AI-Rank/mobile/MobileNetV1.tar.gz
tar zxvf MobileNetV1.tar.gz

# 上传文件
adb shell mkdir /data/local/tmp/benchmark
adb push MobileNetV1 /data/local/tmp/benchmark
adb push build.lite.android.armv8.clang/lite/api/benchmark_bin /data/local/tmp/benchmark
adb push build.lite.android.armv8.clang/third_party/validation_dataset /data/local/tmp/benchmark
adb push lite/api/tools/benchmark/precision_evaluation/imagenet_image_classification/config.txt /data/local/tmp/benchmark

# 执行性能测试
adb shell "cd /data/local/tmp/benchmark;
  ./benchmark_bin \
    --model_file=MobileNetV1/inference.pdmodel \
    --param_file=MobileNetV1/inference.pdiparams \
    --validation_set=ILSVRC2012 \
    --config_path=config.txt \
    --input_shape=1,3,224,224 \
    --warmup=10 \
    --repeats=20 \
    --backend=arm"

部分输出日志如下：

 lite_option(LITE_BUILD_EXTRA                   "Enable extra algorithm support in Lite, both kernels and operators"   OFF)

 # cv build options
+lite_option(LITE_USE_PRECOMPILED_OPENCV        "Use precompiled opencv, mainly for pre/post processing in benchmark"  OFF)


能否用已经支持的CV 加速库？不然lite 里有两个CV，感觉有些混淆
或者benchmark 使用opencv 方法效仿demo/cxx 下的使用方法，不要把他放到主库

已删除该选项

是否能将benchmark的cmake代码都以新的CMakeLists.txt放在tools/benchmark/目录下，然后这里直接include？

可以的，我修改下

config 中冒号是不是用空格隔开，这样看起来好点

嗯，我在下个PR中更新下字符串处理的功能函数。由于这个是样板间，咱们CI执行有些慢，所以考虑基本功能OK的话，就先合入。

后续改为使用 RapidJSON 解析 config.json

没有用的注释能否删除

我在下个PR中删除该调试注释

+  for (int i = 0; i < ele_num; i++) {
+    float score = output_data[i];
+    int index = i;
+    for (int j = 0; j < TOPK; j++) {


这个可以用std::sort 排序

std::partial_sort(vec.begin(),
vec.begin() + topk,
vec.end(),
std::greater<std::pair<float, int>>());

OK 在下个PR中更新此处
