英文:
python3 ModuleNotFoundError with my own modules
问题
![结构][1]
我有这个项目的结构。我想在`data/datadownload.py`中像这样导入我的Restaurant类，从`models/restaurant.py`：
```python
from models.restaurant import Restaurant
但我一直得到ModuleNotFoundError: No module named 'models'。
注意： data和models两个模块都在项目的根目录中。我还尝试通过在根目录中添加__init__.py来使根目录成为一个模块。

I have this project structure. I want to import my Restaurant class from `models/restaurant.py` in `data/datadownload.py` like this:
from models.restaurant import Restaurant
And I keep getting `ModuleNotFoundError: No module named 'models'`.
**Note:** both modules (data and models) are int the root folder of the project. And I also tried to make the root folder a module by adding `__init__.py` in it.

尝试导入位于不同目录中的同一目录内的内容，请尝试使用：
from ..models.restaurant import Restaurant
以使代码更具可移植性。
英文:
You are trying to import something within the same directory that is in a different directory try using:
from ..models.restaurant import Restaurant
to make the code more portable
