name 'mp_face_mesh' is not defined

Hey Patrick,
i installed mediapipe, controlnet_aux but still getting error:
```
from diffusers.utils import load_image
from controlnet_aux.processor import Processor
import torch

image = load_image( "https://huggingface.co/TencentARC/T2I-Adapter/resolve/main/examples/sketch/human.png" )

image.save("human.png")

```
```
Loading base model ()...Done.
Removing last two layers (global_pool & classifier).
