I think Robert wanted to know how you started the program. 
What instruction do you use to launch? 
- used command c:\python27\python.exe c:\project_1\code.py

In what directory are you launching your program?
- working directory was c:
- python is in c:\python27
- code was in c:\project_1
- changed the working directory to c:\project_1 now and it worked

Is that the same directory where train.csv is present? 
- train.csv is present in c:\project_1
