Trying to install xgboost is failing..? The version is Anaconda 2.1.0 (64-bit) on Windows & enterprise. How do I proceed? I have been using R it seems its quite easy to install new package in R from RStudio, but not so in spyder as I need to go to a command-window to do it and then in this case it fails..

import sysprint (sys.version)

I'm a bit late to answer but I would still go ahead and answer it for anyone who still has an issue with the installation. I followed the steps listed in https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13043/run-xgboost-from-windows-and-python Their is a concise version of these steps at https://github.com/dmlc/xgboost/tree/master/windows. I will summarize what I did below.

1) Download Visual Basic Studio. You can download the community edition at visual studio website. There is a "free visual studio button on the upper right corner"

2) Copy all content from the git hub repository of xgboost/tree/master/windows and Open Visual studio existing project on Visual studio

3) There are a couple of drop down menus you need to select ( "Release" and "X64" and then select build --> build all from the upper menu. It should look something like the attached screenshot.

4) if you see the message ========== Build: 3 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========, it is all good

5) Browse to python-packages folder where the setup file for XGB resides and run the install command 'python setup.py install'.

Hope this helps.
