Psychopy stack smashing detected - psychopy

I am trying to execute the following basic psychopy (version 2021.2.3) code through the Python 3.6.13 console:
import psychopy.visual as pv
pv.Window()
Which gives the following error.
*** stack smashing detected ***: <unknown> terminated
Aborted (core dumped)
The only related topic I can find is on the psychopy forum with no answers
I'm running this on an Ubuntu 18.04.05 machine. The machine is initialized as a headless server, but I am trying to run this through RDP.
I installed psychopy using pip inside a conda environment. Initially I was getting errors related to wxPython. When I manually installed wxPython from a whl file that error was resolved and error in this question appeared.

My guess is that this is to do with the version of one of the libraries but very hard to tell from this limited info.
What version of PsychoPy are you trying to install and by what means are you installing it? Are you running from the app or is this a script you're trying to launch from the terminal? ie. trying to work out what parts of PsychoPy this is affecting (the app, the visual lib, the gui libs...?)

I had a very similar problem on ubuntu 18.04.5, psychopy 3.2.4, no headless server. I suspect that the problem is general but ubuntu/drivers related.
My solution was to update the system and to install&switch to a proprietary NVIDIA driver.

OSError: WinError 193 %1 is not a valid Win32 application

I have been working on a project in Visual Studio Code with Python 3.8.5, and I have a windows 64 bit operating system. I decided to upgrade to Python 3.11.1, and downloaded the official 64 bit installer and followed the instructions. All the packages I import at the beginning of my project that were previously working now give this error "[WinError 193] %1 is not a valid Win32 application" when I run the import statements for them.
For some of the packages (pandas, numpy, matploblib) this was solved by using an approach I saw on a few similar questions to this, by opening the command prompt and typing "pip uninstall pandas" etc and then doing "pip install pandas".
However, for the other packages (sklearn, umap, nltk), this isn't working even after trying that process a few times. I've also tried updating pip. Does anybody have any ideas on what could be causing this to work for some packages but not for others? It allows me to install all of the packages via the command prompt, the issue only arises when I actually try and import them via VSCode, and it's the same error for every package. I've seen some suggestions saying to ensure the environment path is clean, but I'm still quite a beginner so I'm a bit unsure as to what that means.
Any help would be really appreciated.

Gazebo GUI Not Showing Up when running WSL2 Graphics on Windows 11

I am attempting to use ROS with the Gazebo GUI. I recently upgraded to Windows 11 for the WSL GUI support and have the gedit GUI working. However, when I run the command $ gazebo, the GUI does not open.
Running $ gazebo --verbose gives the following error messages
[Err] [RenderEngine.cc:749] Can't open display: :0
[Err] [GuiIface.cc:124] This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
After enabling the QT Debug environment variable using export export QT_DEBUG_PLUGINS=1 and rerunning the gazebo command with the verbose option set, It shows me
[Dbg] [GuiIface.cc:112] Got keys from plugin meta data ("xcb")
[Dbg] [GuiIface.cc:112] QFactoryLoader::QFactoryLoader() checking directory path "/usr/bin/platforms" ...
[Dbg] [GuiIface.cc:112] loaded library "/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so"
I believe that I have all of the necessary packages installed from this output, so I am wondering why gazebo is not showing up. I have tried uninstalling/reinstalling gazebo to no avail.
Thank you so much for your time. If I get this problem sorted out, I will post. Please let me know if any other system/output information is needed.
Other information:
I am not using X Server because the Windows 11 upgrade does not require it for graphical WSL applications (but did try it with X Server installed just in case)
I have tinkered around with the ~/.bashrc profile. DISPLAY=0:0 option was set, but I deleted this because Windows 11 did not need it (or so I think?)
Solution:
After reading up online, I found this answer to a similar question to mine.
https://superuser.com/questions/1681647/windows-11-wsl-not-opening-gui-in-my-ubuntu-shell
Getting ubuntu and re-installing gazebo on that worked. Now I can open up the Gazebo GUI.

Packaging with Pyinstaller - PyQt5 setStyle ignored

I'm actually have an similar issue as described here after update python, pyistaller, pyqt5, pyqt5-tools. Before I got the desired "Windows Vista-style" without app.setStyle('windowsvista') when I run the compiled stand-alone executable.
Now I got the Windows "Classic-style" instead. If I start the application in PyCharm it will use the desired "Windows Vista-style".
Currently installed on Win7 64bit:
Python : 3.6.4
PyInstaller: 3.3.1
PyQt5 : 5.10
pyqt5-tools: 5.9.0.1.2 (update to 5.9.1.1 doesn't work)
Does anyone have any idea why PyInstaller ignored the style?
The error seems to have been fixed in a unmerged branch of PyInstaller. More information can be found on the GitHub pull request conversation, but reinstalling PyInstaller using pip install https://github.com/bjones1/pyinstaller/archive/pyqt5_fix.zip fixed the same style issue for me on Mac.

apache2 mod_wsgi crashes when importing pyodbc

Operating system - Ubuntu Server 14.04 on Azure VM
Tried with different versions of python (3.4.3, 3.6.0), apache and mod_wsgi.
Installed MS Native ODBC driver using instructions from here
https://gist.github.com/joecampo/6f777a659b8132b9d6fe1c3589df394c , while pyodbc was installed using pip.
To debug the wsgi_module I have set up the django application to run in embedded mode and:
gdb /usr/local/apache2/bin/httpd
run -X
When I access any function which imports pyodbc, the wsgi fails with the following error:
Program received signal SIGSEGV, Segmentation fault.
import_types () at src/pyodbcmodule.cpp:223
223 src/pyodbcmodule.cpp: No such file or directory.
Importing module works fine when I run the django app from the command line:
python3 manage.py runserver
Is there a workaround?
I experienced the same problem when setting up a Python Pyramid project, and downgrading to a previous version of pyodbc fixed it.
It looks like this may be a bug in pyodbc or the WSGI module. See pyodbc 4.0.9+ segfault with uwsgi #199. You may already be aware that this line is a red herring:
223 src/pyodbcmodule.cpp: No such file or directory.
That error is coming from the debugger and just tells where in import_types() the exception was raised, however searching for that file led me to that bug report on GitHub.
You obviously already know how to debug Apache and wsgi, but for anyone who doesn't there are detailed instructions here.
This has been fixed in 4.0.16 by adding support for subinterpreters.

Simple-OpenNI for Processing fatal errors with the Kinect

I have been using SimpleOpenNI, a wrapper for Processing, all summer now. I use it for the Kinect to make games and demos. Last week, I have been getting a fatal error in my processing window and none of the SimpleOpenNI projects will work. Here is the error:
SimpleOpenNI Version 0.20
A fatal error has been detected by the Java Runtime Environment:
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x72e8f955, pid=4596, tid=4624
JRE version: 6.0_24-b07
Java VM: Java HotSpot(TM) Client VM (19.1-b02 mixed mode windows-x86 )
Problematic frame:
C [OpenNI.dll+0xf955]
An error report file with more information is saved as:
C:\Users\mss042\Desktop\processing-1.5.1\hs_err_pid4596.log
If you would like to submit a bug report, please visit:
http://java.sun.com/webapps/bugreport/crash.jsp
The crash happened outside the Java Virtual Machine in native code.
See problematic frame for where to report the bug.
It appears as if the new OpenNI/NITE/SensorKinect drivers do not work with the SimpleOpenNI wrapper. I have tried it with people using the old drivers and everything still works. Problem is, you cannot download the old drivers off of the websites so I cannot test if it's that or not. You can see everything I've downloaded from the simpleopenni site: http://code.google.com/p/simple-openni/
Any help with this error would be appreciated. Thanks.

It looks like there's a problem with OpenNI.dll. Make sure that:
You have the dll (It should be in Program Files where you've installed OpenNI)
Make sure you've got the Environment Variables for the Open NI paths and that the paths are correct, otherwise, you might have the .dll file, but the .jnilib wouldn't know where it is.
Had a Kinect Workshop in Uni, and my colleagues using Windows all had issues with the drivers,
so I'm just passing on what they did:
Even though they had 64-bit versions of Windows they used the 32-bit version, and used Brekel OpenNI Kinect Auto Installer - Developer Edition v1.3.2.3.exe(direct link via developkinect.com) after reading this message:
Comment 4 by tijmenva...#gmail.com, Oct 21, 2011 Hey all I have Solved
the unsatisfied link dll error on windows 7 64 bits by installing java
runtime (jre-7u1-windows-i586.exe)and (Brekel OpenNI Kinect Auto
Installer - Developer Edition v1.3.2.3.exe) I uninstalled everything
and than it worked :)
hope this helpes
in Issue#17 on the SimpleOpenNI project issues page.
Another colleague used Synapse and OSC in Processing instead of SimpleOpenNI, but she had loads of errors with the drivers (basically spent a few good hours uninstalling/installing different versions). In her case, uninstalling any previous partial or complete drivers from the machine and deleting any registry entries related to PrimeSense(Sensor, Nite) and OpenNI, then using the installers from the links on the Synapse page, worked for her.
HTH
This is a long shot, but that exact error is also given if the Kinect USB and/or power supply simply becomes unplugged. Thought it was worth mentioning as it is not obvious from the error message itself and it may help someone out if they kicked their power supply and started searching for the above exception :)
