Pyinstaller is a fantastic python to exe packager. When I tried making a stand alone exe with a python script (PyQt5Test.py) using a quick PyQt5 example, it creates a working exe file right off the bat using this simple command:
pyinstaller PyQt5Test.py --onefileHere’s PyQt5Test.py:
import sys
from PyQt5.QtWidgets import QWidget, QMessageBox, QApplication
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Message box')
self.show()
def closeEvent(self, event):
reply = QMessageBox.question(self, 'Message',
"Are you sure to quit?", QMessageBox.Yes |
QMessageBox.No, QMessageBox.No)
if reply == QMessageBox.Yes:
event.accept()
else:
event.ignore()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())Running the executable file from the dist folder in works perfectly just as the same way as you just run the script in the interpreter
I left the console option in the background so that if there’s an error I could see it when the program runs. However, you could get rid of the console by adding “–noconsole” option to pyinstaller.
pyinstaller PyQt5Test.py --onefile --noconsoleNow that works so well, I want to see whether I could make a standalone file with a script that has PyQt5 and Matplotlib. Here’s the code I use to test this:
import sys
import PyQt5
from PyQt5.QtWidgets import QApplication, QMainWindow, QMenu, QVBoxLayout, \
QSizePolicy, QMessageBox, QWidget, QPushButton, QListWidget, QDesktopWidget
from PyQt5.QtGui import QIcon
from PyQt5 import QtCore
import PIL
import tkinter
from tkinter import filedialog
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.figure import Figure
import matplotlib.pyplot as plt
import random
class App(QMainWindow):
def __init__(self):
super().__init__()
self.left = 10
self.top = 10
self.title = 'PyQt5 matplotlib example'
self.setFixedSize(640, 700)
self.initUI()
def location_on_the_screen(self):
ag = QDesktopWidget().availableGeometry()
sg = QDesktopWidget().screenGeometry()
widget = self.geometry()
#x = ag.width() - widget.width()
#y = 2 * ag.height() - sg.height() - widget.height()
x = sg.width() - widget.width()
y = 2 * ag.height() - sg.height() - widget.height()
self.move(x, y)
def initUI(self):
self.setWindowTitle(self.title)
#self.setGeometry(self.left, self.top, self.width, self.height)
self.location_on_the_screen()
m = PlotCanvas(self, width=5, height=4)
m.move(0,0)
button = QPushButton('PyQt5 button', self)
button.setToolTip('This s an example button')
button.move(500,0)
button.resize(140,100)
button2 = QPushButton('Plot', self)
button2.setToolTip('Plot Data')
button2.move(500,102)
button2.resize(140,100)
listBox = QListWidget(self)
listBox.setGeometry(QtCore.QRect(120,10,281,192))
listBox.move(500,400)
self.show()
class PlotCanvas(FigureCanvas):
def __init__(self, parent=None, width=5, height=4, dpi=100):
fig = Figure(figsize=(width, height), dpi=dpi)
self.axes = fig.add_subplot(111)
FigureCanvas.__init__(self, fig)
self.setParent(parent)
FigureCanvas.setSizePolicy(self,
QSizePolicy.Expanding,
QSizePolicy.Expanding)
FigureCanvas.updateGeometry(self)
self.plot()
def plot(self):
data = [random.random() for i in range(25)]
ax = self.figure.add_subplot(111)
ax.plot(data, 'r-')
ax.set_title('PyQt Matplotlib Example')
self.draw()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())When creating an exe for this script using Pyinstaller I see a lot of warnings but no errors. I even got an exe. However, when I ran the exe I got an error:
ModuleNotFoundError: No module named ‘numpy.core._dtype_ctypes’
I did have Numpy correctly installed using pip and I have version 1.16.0 and it’s supposedly the most up-to-date version.
After Googling the error, I found that the problem was indeed Numpy itself and the issue is fixed if I have version 1.16.1. However, doing pip install numpy doesn’t work since it insists that 1.16.0 was the up-to-date version.
Therefore, I have to force the install of 1.16.1 Numpy
pip install numpy==1.16.1This forces the new version of Numpy to be installed. I tried to create the exe file again using Pyinstaller. Again, the exe creation went just fine as before. I wasn’t sure whether this would work or not, but to my surprise when running the exe file I have a working program!
I was quite pleased with the result. Now I could move forward with using Pyinstaller to make a standalone program.
