I'm no expert, but installing pyinstaller in wine works for me.  I
admit, though, that I have only tried it with one file, which I wanted
to send to my brother.

I'm using Ubuntu 18.04, and the command: 

wine ~/.wine/drive_c/Python34/Scripts/pyinstaller.exe --onefile
bin/GradientProfile_v2.py

produces a file that my brother can run on his Windows 10 machine.
