+# TIPC Linux端补充训练功能测试
+
+Linux端基础训练预测功能测试的主程序为test_train_python.sh，可以测试基于Python的模型训练、评估等基本功能，包括裁剪、量化、蒸馏训练。
+
+![](./tipc_train.png)
+
+测试链条如上图所示，主要测试内容有带共享权重，自定义OP的模型的正常训练和slim相关功能训练流程是否正常。
+
+
+# 2. 测试流程
+
+本节介绍补充链条的测试流程
+
+## 2.1 安装依赖
+
+- 安装PaddlePaddle >= 2.2
+- 安装其他依赖
+
+```
+pip3 install -r requirements.txt
+```
+
+## 2.2 功能测试
+
+`test_train_python.sh`包含2种运行模式，每种模式的运行数据不同，分别用于测试训练是否正常，分别是：
+
+- 模式1：lite_train_lite_infer，使用少量数据训练，用于快速验证训练到预测的走通流程，不验证精度和速度；
+
+```
+bash test_tipc/test_train_python.sh ./test_tipc/ch_ppocr_mobile_v2.0_det/train_infer_python.txt 'lite_train_lite_infer'
+```
+
+- 模式2：whole_train_whole_infer，使用全量数据训练，用于快速验证训练到预测的走通流程，验证模型最终训练精度；
+
+```
+bash test_tipc/test_train_python.sh ./test_tipc/ch_ppocr_mobile_v2.0_det/train_infer_python.txt 'whole_train_whole_infer'
+```
+
+如果是运行量化裁剪等训练方式，需要使用不同的配置文件。量化训练的测试指令如下：
+```
+bash test_tipc/test_train_python.sh ./test_tipc/ch_ppocr_mobile_v2.0_det/train_infer_python_PACT.txt 'lite_train_lite_infer'
+```
+
+同理，FPGM裁剪的运行方式如下：
+```
+bash test_tipc/test_train_python.sh ./test_tipc/ch_ppocr_mobile_v2.0_det/train_infer_python_FPGM.txt 'lite_train_lite_infer'
+```
+
+运行相应指令后，在`test_tipc/output`文件夹下自动会保存运行日志。如'lite_train_lite_infer'模式运行后，在test_tipc/extra_output文件夹有以下文件：
+
+```
+test_tipc/output/
+|- results_python.log    # 运行指令状态的日志
+```
+
+其中results_python.log中包含了每条指令的运行状态，如果运行成功会输出：
+
+```
