pkuseg 的一个错误
最近在使用pkuseg进行分词，刚接触不久
直接执行了下述代码：
但是会有这个错误出现:

RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.
This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.

最后发现是因为缺少了
if __name__ == '__main__':的保护而导致子进程多次运行。
修改如下后，顺利完成任务：
