+# Lite预测功能测试
+
+Lite预测功能测试的主程序为`test_lite.sh`,可以测试基于Lite预测库的模型推理功能。
+
+## 1. 测试结论汇总
+
+目前Lite端的样本间支持以下四种方式的组合,共16个链条:
+
+| 模型类型 | 样本数量 | 功耗模式 | cpu多线程 |
+| ---- | ---- | :----: | :----: |
+| 正常模型 | 单样本/多样本 | LITE_POWER_HIGH/LITE_POWER_LOW | 支持 |
+| 正常模型 | 单样本/多样本 | LITE_POWER_HIGH/LITE_POWER_LOW | 支持 |
+| 量化模型 | 单样本/多样本 | LITE_POWER_HIGH/LITE_POWER_LOW | 支持 |
+| 量化模型 | 单样本/多样本 | LITE_POWER_HIGH/LITE_POWER_LOW | 支持 |
+
+## 2. 测试流程
+
+### 2.1 功能测试
+
+先运行`prepare.sh`准备数据和模型,模型和数据会打包到test_lite.tar中,将test_lite.tar上传到手机上,然后运行`test_lite.sh`进行测试,最终在`test_lite/output`目录下生成`lite_*.log`后缀的日志文件。
+
+```shell
+
+# 数据和模型准备
+bash PTDN/prepare.sh ./PTDN/configs/ppocr_det_mobile_params.txt "lite_infer"
+
+# 手机端测试:
+bash PTND/test_lite.sh ./PTDN/configs/ppocr_det_mobile_params.txt
+
+```
+
+**注意**:数据上传到手机的方式有两种,一种是通过adb的方式通过数据线连接,可以参考[Lite端部署文档](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/deploy/lite/readme.md)。另外一种是通过在手机上开启虚拟终端在局域网内通过ssh的方式连接,无需数据线,第二种方式可以在手机上支持大部分linux命令,如vim、bash等,比较推荐,可以参考[安卓手机termux连接电脑](./termux_for_android.md)。
+
+#### 运行结果
+
+各测试的运行情况会打印在 `./output/` 中:
+运行成功时会输出:
+
+```
+Run successfully with command - ./ocr_db_crnn det ./models/ch_ppocr_mobile_v2.0_det_slim_opt.nb INT8 4 1 LITE_POWER_LOW ./test_data/icdar2015_lite/text_localization/ch4_test_images/img_233.jpg ./config.txt True > ./output/lite_ch_ppocr_mobile_v2.0_det_slim_opt.nb_precision_INT8_batchsize_1_threads_4_powermode_LITE_POWER_LOW_singleimg_True.log 2>&1!
+Run successfully with command xxx
+...
+```
+
+运行失败时会输出:
+
+```
+Run failed with command - ./ocr_db_crnn det ./models/ch_ppocr_mobile_v2.0_det_slim_opt.nb INT8 4 1 LITE_POWER_LOW ./test_data/icdar2015_lite/text_localization/ch4_test_images/img_233.jpg ./config.txt True > ./output/lite_ch_ppocr_mobile_v2.0_det_slim_opt.nb_precision_INT8_batchsize_1_threads_4_powermode_LITE_POWER_LOW_singleimg_True.log 2>&1!
+Run failed with command xxx
+...
+```
+
+在./output/文件夹下,会存在如下日志,每一个日志都是不同配置下的log结果:
+
+
+
+在每一个log中,都会调用autolog打印如下信息:
