Stand-alone Python software (.exe file) for non-python machines with GUI and TkInter

I am developing software using Python 3.6.5 and need to run it on machines that do not have python installed. It contains some libraries for machine learning and access and excel to MS. I've seen some solutions on the internet to convert it to an .exe file, but it seems the GUI I'm using (TkInter) does not support this. Is there another way to do this using TKinter or maybe I should consider another framework GUI? Thank you.
