System information

• Have I written custom code (as opposed to using a stock
  example script provided in TensorFlow): Yes

(e.g. for links and images), because some of these examples are now being rendered in the docs.

Added by @fchollet in requests for contributions.

The fit_transform docstrings of the VotingClassifier and VotingRegressor are inherited from the TransformerMixin:

Fit to data, then transform it.

Fits transformer to X and y with optional parameters fit_params and returns a transformed version of X.

They don't really apply here and we should use the docstring from transform to explain what is returned:

I just noticed the Random stdlib has an UnsafeView type for filling arrays. With the new layout optimizations, this should no longer be necessary. We should try using the normal SubArray type for this. If it's still too slow/complex, then at least the type can be made safe by holding the underlying array directly instead of a Ptr.
