I installed kivy on my Window 7, Python 2.7. When I run the following code:
import kivy
from kivy.app import App
from kivy.uix.label import Label
class MyApp(App):
def build(self):
return Label(text='Hello World!')
if __name__ == '__main__':
MyApp().run()
it gives the following error:
Unable to get a Window, abort.
I tried on Python 3.4, same error.
There is an option that sdl2 can't find dlls needed to load *.png
Try to find libpng16-16.dll
on my PC is here: C:\Python27\share\gstreamer\bin
Add it to PATH
set PATH=C:\Python27\share\gstreamer\bin;%PATH%
This is temporary solution but it works for me
If you use Windows 10 then you may have two windows 10 installed on that same laptop which then has made it difficult for Python, Kivy and Kivmd to find the Windows to execute the program with so it gives an error.
That is why this commonly happens to partitioned laptops so check your laptop again to know how many windows are installed and delete one of the windows or you can also format your laptop properly to solve these issues. In my case my laptop was formatted.

Last week I started learning Python for Maya, following the 'CGCircuit - Learn Python Inside Maya'.
Now I'm trying to make a simple UI for Maya2020 using Qt. The tutorial itself is pretty outdated, a lot has changed since Maya2015.
I checked a lot of forums and it seems I’m not the only one having problems. This is what I learned so far:
Qt designer is not a part of Maya anymore, so I downloaded Qt Creator 4.14.0 (Community)
I used pip to install: shiboken2-5.15.2-5.15.2-cp35.cp36.cp37.cp38.cp39-none-win_amd64.whl
If I'm correct, Maya2020 has Pyside2 pr-installed, but I also Installed Pyside2 on Windows10
QtGui.QDialog is replaced by QWidget
Currently I ‘m using Python 2.7.17 on my Windows system, but I also have Python3.8 available in my Environment Variable
When I call the py script inside Maya, like this:
import geomGenerator
reload(geomGenerator)
geomGenerator.getMayaWindow()
geomGenerator.run()
I get this error:
Error: NameError: file C:/Users/12213119/Documents/maya/2020/scripts\geomGenerator.py line 12: global name 'shiboken2' is not defined #
Not sure what this means or how I can solve it. I looked all over the internet, please let me know what I'm doing wrong. Thx in regard.
from PySide2 import QtGui, QtCore, QtUiTools, QtWidgets
from shiboken2 import wrapInstance
import maya.cmds as mc
import maya.OpenMayaUI as omui
def getMayaWindow():
""" pointer to the maya main window
"""
ptr = omui.MQtUtil.mainWindow()
if ptr is not None:
return shiboken2.wrapInstance2(long(ptr), QtWidgets.QWidget)
def run():
""" builds our UI
"""
global win
win = GeometryGenerator(parent=getMayaWindow())
win.show()
class GeometryGenerator(QtWidgets.QWidget):
def __init__(self,parent=None):
super(GeometryGenerator,self).__init__(parent)
I guess you need to run you script with python that comes with Maya, and use pip that comes with maya to install packages.
I have written codes but it's showing cannot import pygame module
Download pygame from here: http://www.pygame.org/download.shtml
If you are not sure which version of python you are running, execute the following code in your shell:
import sysconfig
version = sysconfig.get_python_version()
print(version) #Python3
print version #Python2
Usually, Python3 will also accept the print command without brackets, so using sysconfig is the safest way. Sysconfig will also tell you which minor version you are using (such as 3.4.5)
Once you have download pygame, tryimport pygame in your shell. If this does not work, type help('modules'). This will now list all your modules. If pygame is not in there, check in which folder all other modules are saved and move the pygame module to that file path.
You can also use sysconfig to display all the file paths python is using:
import sysconfig
paths = sysconfig.get_paths()
print(paths) #For Python2, see print method above
I don't quite understand what you mean with "And make games", but the pygame website has a great documentary and some example codes to help you learn progamming with the pygame module.
Hope I could help,

I am using Pyinstaller (after spending a long time with py2exe) to convert my REAL.py file to .exe. I used Anaconda to make .py file which is running perfectly on my computer. But when I make .exe file, it shows no error and an application is created in dist\REAL folder. But when I run the .exe file, the console opens and closes instantly.
It should ideally show a GUI window and take inputs and use them to make plots. It does so when I run REAL.py file. I am using Tkinter, Matplotlib, numpy, scipy which comes with Anaconda.
EDIT: I tried to run simple code to check the compatibility with matplotlib:
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()
The same issue persists with this. Opens console window and then closes but no plot is given out.
I found the solution in py2exe. Following was the setup.py file that worked with Tkinter Matplotlib numpy scipy imports:
from distutils.core import setup
import py2exe
from distutils.filelist import findall
import matplotlib
opts = {"py2exe": {
"packages" : ['matplotlib'],
"includes": ['scipy', 'scipy.integrate', 'scipy.special.*','scipy.linalg.*'],
'dll_excludes': ['libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll',
'libgdk_pixbuf-2.0-0.dll']
}
}
setup(
windows = [{'script': "with_GUI.py"}], zipfile = None,
options= opts,
data_files = matplotlib.get_py2exe_datafiles()
)
But this gave me some error saying that there was version conflict with two files. So I changed the two files viz. dist/tcl/tcl8.5/init.tcl (in line 19) and dist/tcl/tk8.5/tk.tcl (in line 18). In my case I changed the version from 8.5.15 to 8.5.18. I found the location of the two files by looking at the path specified by the error in error log. Then the .exe worked just fine.
I hope this helps.
Try using the --hidden-import=matplotlib when calling pyinstaller. For example, in the command prompt you would type:
Pyinstaller --hidden-import=matplotlib your_filename_here.py
and you could try giving it a shot with tkinter in there as well.
Pyinstaller --hidden-import=matplotlib --hidden-import=tkinter your_filename_here.py
So I thought I'd toy around and try and learn Kivy, as it looks interesting. I have just started trying to get one of their examples working:
from kivy.app import App
from kivy.uix.widget import Widget
class MyPaintWidget(Widget):
pass
class MyPaintApp(App):
def build(self):
return MyPaintWidget()
if __name__ == '__main__':
MyPaintApp().run()
I get the following error:
C:\Kivy-1.8.0-py2.7-win32>python paint.py
Traceback (most recent call last):
File "paint.py", line 1, in <module>
from kivy.app import App
ImportError: No module named kivy.app
I have installed the latest version of Kivy. I see "app.py in the C:\Kivy-1.8.0-py2.7-win32\kivy\kivy folder.
Also, here is my PYTHONPATH:
>>> import sys
>>> for n in sys.path:
... print n
...

Any help would be greatly appreciated. Thank you.
I ran into this error message when I named the script kivy.py, because python looks first in the current directory to fill the dependency, so it never sees the real kivy package.
Renaming the script fixed it for me.
The name of the folder or file cannot be kivy or kivy.py. You need to rename it to another name and it will run ok.
So, I figured it out....I was not being very smart. I'm new to Kivy and I'll answer this for anyone else that is as green as I am. You can't just run this as a python program, doh.
Follow instructions [here] (http://kivy.org/docs/installation/installation-windows.html#start-a-kivy-application) and all will be right with the world.
If you installed kivy using pip you need to add the packages to your environment. In Windows Command Prompt do
pip show kivy
~Take note of the Location of the module.
Next you can do 1 of two things.
Configure any python files you write to refer to the location of your module with sys, use this tutorial for more info: https://kivy.org/docs/guide/environment.html
Add the location you found above to your PATH (Windows): https://www.computerhope.com/issues/ch000549.htm
2 Worked for me.
I was also facing the same issue while running sample app.
I followed simple steps given in : https://kivy.org/doc/stable/gettingstarted/installation.html#install-pip
It worked for me.
Create the virtual environment
Activate the virtual environment.
Install Kivy
run your .py file
I know I am too late but I hope this will help others, I just did not run it from the command prompt, I opened the python code in my python shell and then pressed run 'F5' and it worked for me.
If you're using a virtual environment (venv), make sure you're targetting the the correct Python interpreter. See here for how to to change to the venv interpreter in IntelliJ
I'm having trouble running some codes that import cx_Oracle in command line, though the same codes work in console. Is there anything else I will need to set up in order to get this to work via command line please?
Saved just one line of code "import cx_Oracle" as test.py.
Run this line in ide (Spyder), iPython Notebook => no issues
run this by opening a command line window from the same folder the .py file is saved in, and run python test.py and encounter the below:
import cx_Oracle
ImportError: DLL load failed: %1 is not a valid Win32 application.
Not sure if there is anything additional I will need to set up to run cx_Oracle via command line? Have tried all the suggestions on setting PATH, ORACLE_HOME, re-installing but could not get this to work. versions that i'm using are
Python: 2.7
cx_Oracle: cx_Oracle-5.1.3-11g.win-amd64-py2.7
instant client: 12.1.0.0
Windows: 7 Enterprise
I also found this kind of problem.
Look at "not a valid Win32 application" this sentence, so I decide to change cx_Oracle to cx_Oracle-5.1.3-11g.win-32-py2.7. Luckly, it does work.
