## Q & A
## Problems

1. error `There is no current event loop in thread 'AnyIO worker thread` when use api 
issue: https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/9046
fix: https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/9319

in one world.
insert following code snipt before line 70 in webui.py
```python
import asyncio
if sys.platform == "win32" and hasattr(asyncio, "WindowsSelectorEventLoopPolicy"):
    # "Any thread" and "selector" should be orthogonal, but there's not a clean
    # interface for composing policies so pick the right base.
    _BasePolicy = asyncio.WindowsSelectorEventLoopPolicy  # type: ignore
else:
    _BasePolicy = asyncio.DefaultEventLoopPolicy


class AnyThreadEventLoopPolicy(_BasePolicy):  # type: ignore
    """Event loop policy that allows loop creation on any thread.
    The default `asyncio` event loop policy only automatically creates
    event loops in the main threads. Other threads must create event
    loops explicitly or `asyncio.get_event_loop` (and therefore
    `.IOLoop.current`) will fail. Installing this policy allows event
    loops to be created automatically on any thread, matching the
    behavior of Tornado versions prior to 5.0 (or 5.0 on Python 2).
    Usage::
        asyncio.set_event_loop_policy(AnyThreadEventLoopPolicy())
    .. versionadded:: 5.0
    """

    def get_event_loop(self) -> asyncio.AbstractEventLoop:
        try:
            return super().get_event_loop()
        except (RuntimeError, AssertionError):
            # This was an AssertionError in python 3.4.2 (which ships with debian jessie)
            # and changed to a RuntimeError in 3.4.3.
            # "There is no current event loop in thread %r"
            loop = self.new_event_loop()
            self.set_event_loop(loop)
            return loop


asyncio.set_event_loop_policy(AnyThreadEventLoopPolicy())
```

2. `Skipping unknown extra network: lora`
 issue & fix: https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/7984


3. vae-ft-mse-840000-ema-pruned.safetensors 的作用
The intent was to fine-tune on the Stable Diffusion training set (the autoencoder was originally trained on OpenImages) but also enrich the dataset with images of humans to improve the reconstruction of faces.
