xgboost in advanced_requirements.txt unreliable

[calz1]

I am partially to blame because I think I pointed out that xgboost was now in pip but there's some bad news: it appears the version in pip still suffers from a bug that some guy named @ClimbsRocks ran into last summer.

dmlc/xgboost#1238

In other words, I ran into that same ragged data problem when attempting to predict. After reading the thread, I was able to fix it relatively easily by installing XGBoost like described here but you may want to consider backing out the auto install to avoid other people logging XGBoost issues...

Edit: I realized I oversimplified the install to fix this. For Ubuntu, it was the link I said and then the steps farther down that page to install the python package. Together, it is:

git clone --recursive https://github.com/dmlc/xgboost cd xgboost; make -j4

cd python-package; sudo python setup.py install

Drats- I'd forgotten how old that distribution was. I just recently cleaned that workaround out of the codebase as part of some simplification work. Good call on removing XGBoost from the advanced_requirements.txt file for now. Thanks for the continued input!

I see this is gone in the latest version so I think it is moot.
