```bash
python setup.py sdist
# . Check the wheel:
```bash
twine check dist/*
twine upload dist/*
Estimator would be a class like scikit-learn, and user can use them in a easy way, like the following:
```python
import numpy as np
import torecsys as trs
# create training data
x_train = np.array(...) # or even a pandas.DataFrame
y_train = np.array(...)
# initialize a model with the specific arguments
model = trs.estimator.WideAndDeepEstimator(...)
# fit the model by numpy.array / pandas.DataFrame / torch.tensor
model.fit(x_train, y_train)
# make inference
y_pred = model.predict(x_pred)
```
