Easy Python compilation with NUITKA-Utilities

I found a good one

NUITKA-Utilities

https://github.com/Nuitka/NUITKA-Utilities

If you specify the .py file and the output folder, Nuitka will compile it for you. (exe-maker.py)

For Windows, install Mingw-w64 and PySimpleGUI in advance.

conda install m2w64-gcc libpython

pip install nuitka

pip install pysimplegui

Nuitka's standalone has a lot of dlls

Just specify the compiled .dist folder and it will create a single exe file. (Onefile-maker-windows.py)

Install NSIS on Windows in advance.

I want to reduce the size

Use hinted-compilation. (It will not work as of the end of 2019)

https://github.com/Nuitka/NUITKA-Utilities/tree/master/hinted-compilation

When you run get-hints.py, it will pick up only the libraries you need. The size and compile time will be shorter.

I compared it with PyInstaller

I compared it with a handmade python script with GUI of about 60 lines.

from PyQt5 import QtCore, QtGui, QtWidgets
import time

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(300, 200)
        MainWindow.setMaximumSize(QtCore.QSize(300, 200))
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(100, 130, 75, 23))
        self.pushButton.setObjectName("pushButton")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(100, 50, 50, 12))
        self.label.setObjectName("label")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 300, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "Start"))
        self.label.setText(_translate("MainWindow", "Time:"))

        self.pushButton.pressed.connect(calc)

def calc():
    start = time.time()
    i = 10000000
    while i >= 0:
        i = i - 1
    stop = time.time()
    ui.label.setText(str(stop - start))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

It's a pity that it takes a while to start, but the size is half. Since it is a compiled binary, the execution speed is a little fast. It took 55 seconds to compile on my PC and 43 seconds to create a single exe. pyinstaller made a single exe in about 20 seconds.

bonus

When I run nuitka from the command line, I wonder how to add options.

First, if you remove all the libraries, compile, and execute the created executable file, you will be scolded that the library is insufficient, so if you add it as appropriate, it will be completed someday.

python -m nuitka hoge.py --standalone --recurse-none --remove-output

Since hoge.exe is created in hode.dist, execute it on the command line.

The error that is returned is different in how to add options.

• Nuitka:WARNING:Use '--plugin-enable=Hoge' for: Inclusion of Hoge plugins.

At the time of Warning, add --plugin-enable = and --recurse-to =. Qt and numpy are of this type. --plugin-enable=qt-plugins --recurse-to=PyQt5 --plugin-enable=numpy --recurse-to=numpy

• ModuleNotFoundError: No module named 'Hoge'

When ModuleNotFoundError, add only --recurse-to =. Pyserial and OpenCV are this type. --recurse-to=serial --recurse-to=cv2

If you can start it happily, you can reduce the distribution size by checking and deleting unnecessary dlls. For example, if you use Qt as a GUI library, you can delete the Tcl and Tk dlls. If you don't use the network, you can delete the SSL and socket dlls.
