    mysql_select_db("DB_name");

    $sql = "SELECT user_id FROM users WHERE auth_token='$auth_token'";
    $result = mysql_query($sql);

    {
        echo "fail auth_token ".$auth_token;
        exit;
    }

Please help, in log write error in 2 line ( from moviepy.editor import * ) but why I not have error where call ( python gif.py )?

The error is not shown in the last line of your error report: RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data I would say it's probably a permissions problem with the /var/www/ folder not allowing the script to create the file as needed. — Kypros

As discussed in the comments the problem is shown in the last line of your error report, see:

RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data

I would say it's probably a permissions problem with the /var/www/ folder not allowing the script to create the file as needed.

To fix that you should change the permissions on the folder to make it writable or specify a different directory to which the script should create the needed file.
