推荐答案

这是权限问题，访问Python文件。当你运行它通过服务器python脚本访问作为apache用户（最可能是WWW的数据）。因此Apache用户不具有权限才能执行的Python文件。

This is permission problem to access python file. When you running it through server python script access as apache user(most probably www-data). So apache user doesn't having privilege to execute the python file.

您可以做的是运行这个命令sudo的，并添加所有必要的访问Apache用户（WWW的数据）在/ etc / sudoers文件，如下示例。

What you can do it is run this command as sudo and add all necessary access to apache user(www-data) in /etc/sudoers file as below sample.

 www-data ALL=NOPASSWD:/var/www/similarity.py
 www-data ALL=NOPASSWD:/usr/bin/python

这仅仅是样品，你应该改变这一行根据您的环境。

This is just the sample, you should change this line as according to your environment.
