'NoneType' object is not iterable

[mbahmani]

Describe the bug

Just installed the auto-sklearn on Google Colab, and I got the following error when I tried to fit the model.

To Reproduce

1. Go to 'google Colab'
2. On the notebook, I tried to install auto-sklearn based on the installation page
3. Then I created a model based on the this example
4. See the following image error:
   

Expected behavior

Fit the Model with no error.

Actual behavior

Fit the Model with some errors. which you see in the photo.

1. AttributeError: 'AutoSklearnClassifier' object has no attribute 'load_models'
2. TypeError: 'NoneType' object is not iterable

Although this error is observed, I could use the automl object to print all the models (automl.show_models()).

Environment and installation:

• google colab
• Python version: 3.6.9
• Auto-sklearn version: auto-sklearn

Thanks a lot for reporting this issue. It is indeed only an issue in printing the model returned by fit() - you can therefore use it without any issues further down in your notebook.

This is only an issue for notebook users and does not affect other users.

Great! Thanks for the quick response.

Re-opening this issue to remember us to fix this nuisance.

I confirm this issue is the same as #1061 which is fixed by #1063

I am closing this to avoid having duplicates.
