When I try to import cv2 when using pyqt5 I have this error :
ImportError: /lib64/libQt5Widgets.so.5: symbol _ZN23QPlatformSystemTrayIcon16staticMetaObjectE, version Qt_5 not defined in file libQt5Gui.so.5 with link time reference
If I only import cv2 or pyqt5 there are no errors, but together it doesn't work.
What can i do to resolve my problem ?
import sys
import os
import cv2
from PyQt5.QtWidgets import QApplication
import mainWindow
class Application:
def __init__(self):
self.mainWindow = mainWindow.MainWindow()
if __name__ == '__main__':
app = QApplication(sys.argv)
application = Application()
sys.exit(app.exec_())

i want to build app with pyqt5 in python but i got some error while running it i tried to solved it but i cant because im newbie to this
i want to show the picture there are 1 frame, 1 button while pressing button on gui that i made from designer pyqt5-tools the picture shown up on frame.
here is my code and where is my fault, can you fix it?
import sys

from uic import loadUi
class ShowImage (QMainWindow):
def __init__(self):
super(ShowImage,self).__init__()
loadUi('GUI.ui',self)
self.image=None
self.loadButton.clicked.connect(self.loadClicked)
#pyqtSlot()

self.loadImage('smarthealth.jpg')

if (self.image.shape[2])== 4:
qformat=QImage.Format_RGBA8888
else:
qformat=QImage.Format_RGB888
img=QImage(self.image,self.image.shape[1],self.image.shape[0],
self.image.strides[0],qformat)
img = img.rgbSwapped()
self.imgLabel.setAlignment(QtCore.Qt.AlignHCenter|QtCore.Qt
.AlignVCenter)
app=QtWidgets.QApplication(sys.argv)
window= ShowImage()
window.setWindowTitle('Show Image GUI')
window.show()
sys.exit(app.exec())
i'm trayin to create a gui that run a flask application using this example https://github.com/onur2677/PyQt-Flask
in this exemple they use pyqt 4
i'm trying to use pyqt 5 so i made some changes
but the mainwindow open and close in the same time
this is my code for the gui
import sys
from PyQt5 import *
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
import psycopg2
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5 import *
from PyQt5.QtCore import QUrl
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtCore import QEventLoop
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtWidgets import QApplication
PORT = 5000
ROOT_URL = 'http://localhost:{}'.format(PORT)
class FlaskThread(QThread):
def __init__(self, application):
QThread.__init__(self)
self.application = application
def __del__(self):
self.wait()
def run(self):
self.application.run(port=PORT)
def createGuiFor(application):
qtapp = QApplication(sys.argv)
webapp = FlaskThread(application)
webapp.start()
qtapp.aboutToQuit.connect(webapp.terminate)
webview = QWebEngineView()
webview.load(QUrl(ROOT_URL))
webview.show()
webview.setWindowTitle("MyApp")
webview.setContextMenuPolicy(QtCore.Qt.NoContextMenu)
return qtapp.exec_()
if __name__ == '__main__':
from MyWebApp import app
app = QApplication(sys.argv)
sys.exit(app.exec_())
sys.exit(createGuiFor(app))
and this is the flask application that will run in the gui
from flask import Flask ,render_template
app = Flask(__name__)
#app.route("/")
def hello():
return render_template("index.html")
if __name__ == "__main__":
app.run()
for any one ho want to use flask and pyqt there is an example
here https://github.com/smoqadam/PyFladesk
that work for me perfectly
EDIT:
Here is the same code with PySide6
https://github.com/eliaweiss/PySide6Fladesk.git
I have an issue where like many others i can't run some pyqt5 code because i get the error that vscode can't find the module QApplication when i run the command from pyqt5.QtWidgets import QApplication.
Here is my code:
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import QApplication
app = QApplication(sys.argv)
ui = uic.loadUi("interface.ui")
ui.show()
def recherche():
if ui.NomProduit.text()!="":
produit = str(ui.NomProduit.text())
else:
ui.NomProduit.setText("Veuillez rentrez le nom d'un produit")
ui.Recherche.clicked.connect(recherche)
I edited from PyQt5 import Uic to from PyQt5.uic import loadUi and I used Opject Oriented Programing (OOP) . And I imported all methods From PyQt5.QtWidgets import *
Try this :
import sys
from PyQt5.uic import loadUi
from PyQt5.QtWidgets import *
app = QApplication(sys.argv)
class Main(QMainWindow):
def __init__(self):
super().__init__()
loadUi("interface.ui", self)
self.show()
self.Buttons()
def Buttons(self):
self.Recherche.clicked.connect(self.recherche)
def recherche(self):
if self.NomProduit.text()!="":
produit = str(self.NomProduit.text())
else:
self.NomProduit.setText("Veuillez rentrez le nom d'un produit")
ui = Main()
app.exec_()
I'm currently building an app that uses OCR to extract data from PDF files using PYQT5, and I need to use the terminal to convert the pdf into jpeg's before running the OCR; however, when I run this subprocess after compiling it crashes, but it works perfectly if I don't compile the program.
It seems to me that the problem lies within the subprocess call. I've tried many different ways, but I don't know why my app keeps crashing after I compile and run the conversion.
NOTE: For PDF to JPEG I'm using ImageMagick
Currently using to compile:
py2applet --make-setup main.py
python3 setup.py py2app
Converter.py:
from subprocess import call
from PIL import Image
import pytesseract
from PyQt5 import QtWidgets
from ocrgui import Ui_MainWindow
class ImageConverter(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.show()
self.sbmt_btn_convert.clicked.connect(self.convert_image)
def convert_image(self): #Converts image into jpeg
text = str(self.input_convert.text())
output = str(self.output_convert.text())
convert = 'converted.jpeg'
call('convert -density 300 ' + text + ' ' + convert, shell=True)
im = Image.open(convert)
text = pytesseract.image_to_string(im, lang = 'eng')
file = open(output,'w')
file.write(text)
file.close()
call('rm converted.jpeg', shell=True)
print('Succesfully created')
Main.py:
import sys
from PyQt5.QtWidgets import QApplication
from calculator import CalculatorWindow
app = QApplication(sys.argv)
calculator = CalculatorWindow()
sys.exit(app.exec())
I think that problem in the next module:
pathPython\Lib\site-packages\PIL\ImageQt.py
Try to put # on the next lines:
...
try:
from PyQt5.QtGui import QImage, qRgba, QPixmap
from PyQt5.QtCore import QBuffer, QIODevice
qt_version = '5'
except (ImportError, RuntimeError):
print("except (ImportError, RuntimeError):!!!!!!!!!!!!")
#try:
# from PyQt4.QtGui import QImage, qRgba, QPixmap
# from PyQt4.QtCore import QBuffer, QIODevice
# qt_version = '4'
#except (ImportError, RuntimeError):
# try:
# from PySide.QtGui import QImage, qRgba, QPixmap
# from PySide.QtCore import QBuffer, QIODevice
# qt_version = 'side'
# except ImportError:
# qt_is_installed = False
...
I've got code with PyQt:
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtWebKit import *
def main():
page = raw_input('Escriu una web: ')
app = QApplication(sys.argv)
view = QWebView()
view.settings().setAttribute(QWebSettings.JavascriptEnabled, True)
view.load(QUrl(page))
view.setWindowTitle('Titanicus 0.1')
view.show()
app.exec_()
if __name__ == '__main__':
main()
And my setup.py file is this:
import sys
from cx_Freeze import setup, Executable
setup(
name = "On Dijkstra's Algorithm",
version = "3.1",
description = "A Dijkstra's Algorithm help tool.",
executables = [Executable("nautilus.py")])
I've the folder build but when I try to open th new exe file it returns me that error:
File "ExtensionLoader_PyQt4_QtGui.py", line 11, in <module>
ImportError: No module named atexit
Help please!
I'd try adding options = {"build_exe" : {"includes" : "atexit" }} to setup.py,
ref. https://bitbucket.org/reclosedev/cx_freeze/src/f3cacc2fd45a/samples/PyQt4/setup.py
Try something like this:
