Running sklearn trained classifier in a windows machine without Python
The simplest thing to do is to get Python installed properly on your production system. If you aren't able to do this for whatever reason, you can still run Python without installing it, but it's a bit more work to get everything to work properly, particularly if you don't have Administrator privileges.

If you truly can't install Python, your best bet would probably be to use something like py2exe to build a self-contained version of your application that includes a Python interpreter and required libraries.
