你们官网说支持pip方式安装，可是，当我执行pip install paddlepaddle时，却是如下结果:

Collecting paddlepaddle==1.1.0
Cache entry deserialization failed, entry ignored
Could not find a version that satisfies the requirement paddlepaddle==1.1.0 (from versions: )
No matching distribution found for paddlepaddle==1.1.0
You are using pip version 9.0.1, however version 18.1 is available.

我的系统是ubuntu16.04
