How to use?

Hi thanks for making the tool in a nice python package, I have a question about the MWE on homepage,
```python

from qtt import QuickTuner, get_pretrained_optimizer
from qtt.finetune.image.classification import fn

# Load task information and meta-features
task_info, metafeat = extract_task_info_metafeat("path/to/dataset")

# Initialize the optimizer
optimizer = get_pretrained_optimizer("mtlbm/full")
optimizer.setup(128, metafeat)

# Create QuickTuner instance and run
qt = QuickTuner(optimizer, fn)
qt.run(task_info, time_budget=3600)
```

function `extract_task_info_metafeat` is not present anywhere in the repository. Am I missing something here?

Start with the homepage MWE shown in the issue and search the repository for extract_task_info_metafeat. Check whether the example references a renamed or missing API; done means the example uses an available function or clearly documents the required replacement.
