Resetting online mode

```python
cotracker = torch.hub.load("facebookresearch/co-tracker", "cotracker3_online").to(device)
```

Is there any way to reset the above? I see that it keeps outputting larger and larger trajectories while the video rolls out. That's great! But how do we tell the model it's receiving a new video and reset it? Do we have to load it each time?
