-- go: 1.9.2 and later
-- git：2.17.1 and later
-- cmake：3.2.2 and later
-- python：2.7.2 and later

 It is recommended to use Docker for compilation. We have prepared the Paddle Serving compilation environment for you: 
 
 - CPU: `hub.baidubce.com/paddlepaddle/serving:0.2.0-devel`，dockerfile: [Dockerfile.devel](../tools/Dockerfile.devel)
 - GPU: `hub.baidubce.com/paddlepaddle/serving:0.2.0-gpu-devel`，dockerfile: [Dockerfile.gpu.devel](../tools/Dockerfile.gpu.devel)
 
-This document will take Python2 as an example to show how to compile Paddle Serving. If you want to compile with Python 3, just adjust the python options of cmake.
