+# 第一次启动（CPU开发）
+docker run -it --cpu-shares=20000 --name=username --net=host --privileged --rm -v $(pwd):/Paddle hub.baidubce.com/paddlepaddle/paddle:latest-dev /bin/bash

+# 后面几次启动
+docker exec -it username bash
+```
+
+不同开发者启动docker的命令不一样，以上只是推荐命令。如果使用自己习惯的命令，一定要加参数--privileged（GPU的CUPTI库调用需要）

 关于编译 PaddlePaddle 的源码，请参见[从源码编译](../../../install/compile/fromsource.html) 选择对应的操作系统。

+## 单元测试
+
+    单测运行（重复运行多次，避免随机失败）如重复运行100次的命令如下:
+    ctest --repeat-until-fail 100 -R test_xx

 关于单元测试，可参考[Op单元测试](../new_op/new_op.html#id7) 的运行方法。
