assert statement fails in exponentiated gradient reduction (sklearn compatible) notebook

[nrkarthikeyan]

The assert statement

assert egr_aoe_race<lr_aoe_race

used in the notebook example demo_exponentiated_gradient_reduction_sklearn.ipynb seems to fail when run in travis while it passes locally. Needs further investigation.

For now, we commented this to merge PR #215, but we can incorporate this test back again after fixing this issue.
