这段代码定义了一个名为 `init_pipeline` 的方法,该方法创建了一个名为 `pipeline` 的 `Pipeline` 对象,并将 `engine` 属性设置为 `'EN'`。然后,该方法返回了一个值,但是代码中没有给出返回值,因此该方法返回值为 `None`。如果您需要更多上下文或代码,请提供更多信息。

根据错误提示,似乎你在某个地方使用了 `self.saved_color_photos`,但是 `MyWindow` 类中并没有定义这个属性,因此出现了 `AttributeError`。你需要在 `__init__()` 方法中定义 `self.saved_color_photos` 和 `self.saved_depth_photos` 两个属性,例如:
```python
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.thread_list = []
self.image_thread = None
self.saved_color_photos = 0 # 定义 saved_color_photos 属性
self.saved_depth_photos = 0 # 定义 saved_depth_photos 属性
self.init_ui()
# 省略其他方法
```
这样就可以避免出现上述错误了。
