Hey, When I set python3.5 as default, I got a error. So, I corrected it to python2.7, However, roscore gave me a Error like this

~$ roscore

... logging to /home/wuxueming/.ros/log/67c4edca-e9fb-11e8-a50a-7c2a314f2b58/roslaunch-wuxueming-n8xejek-28640.log

The traceback for the exception was written to the log file

How to solve the problem? Thanks so much.

Sorry for later. A long time ago, I had saved this problem .

It just need to open terminal and input this

$ sudo update-alternatives --config python
有 2 个候选项可用于替换 python (提供 /usr/bin/python)。

  选择       路径            优先级  状态
  0            /usr/bin/python3   150       自动模式
* 1            /usr/bin/python2   100       手动模式
  2            /usr/bin/python3   150       手动模式

Next you need to chose python2, just it looks like, push the number 2 & Enter. Everything is OK.
