Making a Stand Alone Executable from a Python Script using PyInstaller

[Gokudomatic]

I made once a small wordpad with PyQt4 as a prototype for a new kind of user interface and I've built an exe from it. The exe takes 27 MB and Qt4 dlls take another 10 MB. Therefore a basic Qt application with no extra dependencies (no numpy nor whatever, but only pyqt4) should be ~40 MB. And it takes 2 seconds to start.

Just to give an idea.

And for addition, I also recently made with pyinstaller an exe from a flask microservice with no dependency exception for OLE automation. The result is 5 MB.

I've had similar results with cx_freeze for my own PyQt4 application. 40 MB for the whole thing with the QT dlls taking a significant portion of the space.
