After Installing Paddle with the one-click install script, I tried to run import paddle.v2 as paddle in Python. But an error occurred:

Type "help", "copyright", "credits" or "license" for more information.
>>> import paddle.v2 as paddle

So far this error only occurs on machines of Baidu's internal network.

We have found a trick to solve this problem: There is a file named _sqlite3.so in {paddle_install_folder}/python27/lib/python2.7/lib-dynload, find and replace it with another available _sqlite3.so. You can find one in Jumbo's folder if you have installed Sqlite3 with Jumbo.

However, that's not a normal practice. The fundamental reason still needs to be found out.
