fetch_lfw_people time out

See original GitHub issue

Description

Example under the Face Recognition fails, because datasets/fetch_lfw_people timesout. In fact the resource home is down. I think scimitar examples should not rely on data being stored somewhere else, and should be self-sustained. Otherwise, if some other website goes down, changes domain, or changes the data path, the examples will be broken.

Steps/Code to Reproduce

from sklearn.datasets import fetch_lfw_people
data = fetch_lfw_people()

Actual Results

No handlers could be found for logger "sklearn.datasets.lfw"
