Im̀ trying to create a code that uses kivy library to create a window that has a button as widget. To do that I used the following code copied from a online video so as far as I know it should work:
(Each running cell will be divided by some dots, as the first one runs with no problems but the second is where the error occures)
from kivy.app import App
from kivy.uix.button import Button
from kivy.interactive import InteractiveLauncher
from kivy.lang import Builder
#forzar a la app a no iniciar en pantalla completa
from kivy.config import Config
Config.set("graphics", "fullscreen", "0")
janela = None
glayout= None
...
class WindowApp(App):
pass
window = WindowApp()
wi = InteractiveLauncher(janela)
wi.run()
#the error that appears on the console after running the second cell goes like this:

After running the last cell a black window that crashes appears. So far Im quite new to using the Kivy library so Im̀ quite lost about what counld have gonne wrong since I've seen this code run without problems online.

I am using windows 10 and anaconda3 to manage my python packages. This is my first time to use python, and I'm trying to make my own gui program with pyqt5. Also I'm trying to make .exe file using Pyinstaller. The issue I am running into is that the .exe is throwing the error block:

ValueError: Can't mix absolute and relative paths
The same error occurs regardless of which .py file is used. For information, I wrote the used code below.
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout
class MyApp(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
btn1 = QPushButton('&Button1', self)
btn1.setCheckable(True)
btn1.toggle()
vbox = QVBoxLayout()
vbox.addWidget(btn1)
self.setLayout(vbox)
self.setWindowTitle('QPushButton')
self.setGeometry(300, 300, 300, 200)
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = MyApp()
sys.exit(app.exec_())
I uninstalled and reinstalled pyinstaller but it didn't work. I don't think its a code issue because the code is really simple. Can anyone give a solution or hint for this problem?
What happened for me is that the absolute path name had a space in it. Once the project was moved to a directory without spaces it was able to build
The solution of this problem is to use the full file name and append the flag -F to the file name. In your case for example if for the file App_ver05.py the absolute path is :
/home/user123/Desktop/foldername/App_ver05.py
Then use the command :
pyinstaller -F /home/user123/Desktop/foldername/App_ver05.py
I am trying to create non-blocking tkiner messagebox using multithreading. I know messagebox is not defined in this way, but I preferred the messagebox concept and functions. I am having actual main program which is quite large and complex so showing some example
program toto.py
import threading
from disp_message import disp_message
msg =" This is a test message"
msgtype = 1
t1 = threading.Thread(target=disp_message, args=(msg,msgtype,))
t1.start()
t1.join()
for i in range(100000):
print(i)
disp_message(msg,msgtype)
print("Done!")
disp_messagee python function code in another file
from tkinter import *
from tkinter import messagebox
def disp_message(msg,msgtype):
top = Tk()
top.withdraw()
if msgtype==1:
messagebox.showwarning("Warning",msg)
elif msgtype==2:
messagebox.showinfo("information",msg)
else:
messagebox.showerror("Error",msg)
When I run this program i am having 2 issues
1. Following error

Secondly it displays messagebox and wait for acknowledgement.
While my objective is to display messagebox and parallel let program get executed and finished.
Can you pl help ?
I'm new to python, that is the first problem.
Secondly I am trying to automate the task of adding vector point layers from spreadsheets (xlsx-files) with Python.
The task can be done manually with the plugin "add spreadsheet layer".
I have a folder with roughly 20 xlsx-files that need to be added into the QGIS-project as vector point layers.
I have tried the following code snippet, to check if the core task of adding a spreadsheet layer actually works:
The Computer has a Win7 OS. The program in question is Python which is contained in the program QGIS 3.4.
The Plugin that I want to control through python is called "add spreadsheet layer".
from qgis.core import *
import processing
processing.run("qgis:createpointslayerfromtable",
{'INPUT':r'C:\Users\Desktop\PlayItAll\Test.xlsx',
'XFIELD':'X_Pos',
'YFIELD':'Y_Pos',
'ZFIELD':None,
'MFIELD':None,
'TARGET_CRS':QgsCoordinateReferenceSystem('EPSG:4326'),
'OUTPUT':r'memory'})
It produces this error:
File "C:/PROGRA1/QGIS31.4/apps/qgis/./python/plugins\processing\core\Processing.py", line 183, in runAlgorithm
raise QgsProcessingException(msg)
I have contacted the programmer of the plugin and he gave me this code to try:
import processing
processing.runAndLoadResults("qgis:createpointslayerfromtable",
{
'INPUT':r'C:\Users\username\Desktop\Delete\test.xlsx',
'XFIELD':'Longitude',
'YFIELD':'Latitude',
'ZFIELD':None,
'MFIELD':None,
'TARGET_CRS':QgsCoordinateReferenceSystem('EPSG:4326'),
'OUTPUT':'memory'
})
For him it worked, for me it didn't.
I got this on the processing tab:

need help to resolve the problem

One problem with your code is that you are trying to load chromedriver.exe which can be found in your current directory but after freezing it cannot be loaded anymore. When you want to freeze your app with Pyinstaller you first need to add that file to your output executable and then load it from the temp directory.
I'm not sure about auto-py-to-exe but you can use the below code and then use
pyinstaller -F --add-data "chromedriver.exe;." yourscript.py
from selenium import webdriver
import resource
import sys
import os
def resource_path(relative_path):
if hasattr(sys, '_MEIPASS'):
return os.path.join(sys._MEIPASS, relative_path)
return os.path.join(os.path.abspath("."), relative_path)
fn = resource_path('chromedriver.exe')
browser = webdriver.Chrome(fn)
browser.get('website')
# fill in username and hit the next button
username = browser.find_element_by_id('user_login')
username.send_keys('xxxxxxx')
password = browser.find_element_by_id('user_pass')
password.send_keys('xxxxxxxxxx')
nextButton1 = browser.find_element_by_id('wp-submit')
nextButton1.click()
browser.get('website')
nextButton2 = browser.find_element_by_class_name('add-new-h2')
nextButton2.click()
nextButton3 = browser.find_element_by_id('is_continue_no')
nextButton3.click()
nextButton4 = browser.find_element_by_class_name('rad10')
nextButton4.click()
Solved in the simplest way, pass the proyect folder with the script to
disk C: and the errors were solved gave error while it was saved in disk E:
