some mistakes in Paddle installation wiki of docker version
Created by: fifar
As mentioned in the Chinese installation wiki, there are 6 docker images, such as paddledev/paddlepaddle:latest-cpu. But from docker images repository, the useful ones are images like paddledev/paddle:cpu-latest. So, command of Installing and Running docker image should be as follows,
$ docker run -it paddledev/paddle:cpu-latest
Thanks.
