Hi All,

I have issue with running gridsearch using TuneGridSearchCV and got error on ray worker and redis server.

This is the codes that I used:

```python
from tune_sklearn import TuneGridSearchCV, TuneSearchCV

grid_search = TuneGridSearchCV(
                            estimator, # sklearn.RandomForestRegressor
                            param_grid, # has been defined in config
                            cv=cv, # 5
                            scoring=scoring, # MAPE
                            return_train_score=True,
                            n_jobs=Config.MODELLING_CONFIG['GRID_SEARCH']['n_jobs'], # 8
                            loggers=['mlflow'],)

```

**PC Spec**

- Windows 10
- python 3.7.4

ray tune installation steps:

```auto
pip install ray[tune] tune-sklearn 

```

I have tried adding the following but it didn’t work 🙁

```python
ray.init(address='auto')

```
