I installed Anaconda python on Windows 7, and then installed the xgboost package manually using the instructions here: How to install xgboost package in python (windows platform)? (It did not get installed under anaconda, but in a separate directory)
I put the following in test.py:
import sys
sys.path.append('C:<path>/xgboost/python-package')
import xgboost
When from a command line (say, from cygwin) the import works fine. But, if I use the Spyder IDE or IPython that came with Anaconda, I get
WindowsError Traceback (most recent call last) <ipython-input-14-afdaff4619ce> in <module>()

I've checked sys.executable, and I'm running the same python in shell and IPython. printing sys.path shows that the proper location is part of the path in both cases. Any idea what is happening? I'd really like to be able to use the IDE.
