我成功安装了 pyttsx3pip install pyttsx3并编写了以下代码：

import pyttsx3 

def speak(text):
     engine = pyttsx3.init()
     engine.say(text)
     engine.runAndWait()
text = 'hello'
speak(text)

当我运行代码时，出现以下错误：

Traceback (most recent call last):
File "/home/walter197/.local/lib/python3.6/site-packages/pyttsx3/__init__.py", line 20, in init
eng = _activeEngines[driverName]
File "/usr/lib/python3.6/weakref.py", line 137, in __getitem__
o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred: 

Traceback (most recent call last):
File "scrap.py", line 104, in <module>
speak(text)
File "scrap.py", line 100, in speak
engine = pyttsx3.init()
File "/home/walter197/.local/lib/python3.6/site-packages/pyttsx3/__init__.py", line 22, in …

我有以下结构：

typedef struct Position Position;
struct Position
{
    int x; 
    int y; 
};

我想定义一个新类型，它是 Position struct 的二维数组。我怎样才能做到这一点？返回此类数组的函数的类型是什么？
