This callback function should take the following arguments: `pipeline`, `i`, `t`, and `callback_kwargs` (this must be returned). Set the pipeline's `_interrupt` attribute to `True` to stop the diffusion process after a certain number of steps. You are also free to implement your own custom stopping logic inside the callback.  
In this example, the diffusion process is stopped after 10 steps even though `num_inference_steps` is set to 50.  
```python
from diffusers import StableDiffusionPipeline
