If you are using python package, please provide

1. The python version and distribution Python 2.7.11 (default, Jun 2 2016, 13:36:37) [ICC v.1600 64 bit (amd64) with MSC v.1500 CRT] on win32

   Steps to reproduce

2. Download src from github and follow guide in here to build libxgboost.dll
3. Use Python to install
4. Python -c "import xgboost"

   What have you tried?

5. Use a pre-built version (20161029) dll to replace the original one

[AbdealiLoKo]

It is probably because one of you *.pyc files are corrupt. Can you do a fresh make after deleting all the .pyc ?

[NKUCodingCat]

Well, I tried the latest dll in Guido Tapia’s blog and delete each *.pyc file I could find but it does not help, Let me try to make by myself

[NKUCodingCat]

Build my myself does not help, neither.
