pkuseg对文件分词时报错

使用pkuseg对文本文件进行分词时踩坑，

官方示例如下：

import pkuseg

# 对input.txt的文件分词输出到output.txt中
# 开20个进程
pkuseg.test('input.txt', 'output.txt', nthread=20)

报错如下：

        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.

解决方法如下：

import pkuseg
if __name__ == '__main__':
    pkuseg.test('input.txt','output.txt', nthread=20)
