Doubts regarding Compile on Linux from Source Code using docker

[akshatvishu]

hey, I wanted to raise my first PR for paddle but having trouble on how to complie on linux from source code.
I followed all the instructions mentioned at https://www.paddlepaddle.org.cn/documentation/docs/en/install/compile/linux-compile_en.html and was looking to build CPU version of PaddlePaddle using docker. The only change I made was in the step1

I've just changed a single step from above instruction, which is shown below:

1. First select the path where you want to store PaddlePaddle, then use the following command to clone PaddlePaddle’s source code from github to a folder named Paddle in the local current directory:

git clone https://github.com/akshatvishu/Paddle.git

Note: I used my fork
Now , my doubt is , how to execute this step :

Congratulations, now that you have successfully installed PaddlePaddle using Docker, you only need to run PaddlePaddle after entering the Docker container. 

I've tried using the vscode dev container extension and then use the Attach to Running Container command but when I try to do test paddle by importing it ; it says No module name paddle
