Introduction
OpenGL is a popular set of programming interfaces that allows developers to create high-performance 2D and 3D graphics applications. Python offers an interface for OpenGL, but it can be challenging to work with due to various errors like ‘No Handlers Found.’ This error is quite common when using Python’s OpenGL library.
In this article, we will examine ways to fix the ‘No Handlers Found’ error in Python’s OpenGL library. We will discuss various methods to solve this error, compare them, and give our opinions on each method.
What is the ‘No Handlers Found’ Error?
The ‘No Handlers Found’ error is a runtime error that occurs while running Python code that involves the use of OpenGL library. The error message indicates that Python has not found a handler to deal with a particular event that the code requires.
This error can occur due to various reasons, such as missing dependencies, wrong installation of the OpenGL library, incorrect python environment setup, etc.
Methods to Fix the ‘No Handlers Found’ Error
Method 1: Installing PyOpenGL 3.1.5
The first method to fix the ‘No Handlers Found’ error is to install PyOpenGL 3.1.5. This method involves uninstalling the previously installed version of PyOpenGL and installing version 3.1.5 instead.
The advantage of this method is that PyOpenGL 3.1.5 is specifically designed to work without errors on various operating systems, including Windows, Linux, and macOS.
Method 2: Upgrading PyOpenGL
An alternative method to fix the ‘No Handlers Found’ error is to upgrade the PyOpenGL package to the latest version available. This method involves using Python’s pip package manager to download the latest version of the PyOpenGL library and updating the installed packages.
The advantage of this method is that it ensures that you are using the latest version of PyOpenGL, which has improved features and bug fixes.
Method 3: Installing Dependencies
Another method to fix the ‘No Handlers Found’ error is to install the required dependencies explicitly. This method involves installing SDL, free GL, GLEW, and other OpenGL dependencies separately from PyOpenGL.
The advantage of this method is that it allows you to have better control over the specific versions of the dependencies you want to install.
Comparison of Different Methods
We have discussed different methods to fix the ‘No Handlers Found’ error in Python’s OpenGL library. Now, let us compare these methods based on their advantages and disadvantages.
| Method | Advantages | Disadvantages |
|---|---|---|
| Installing PyOpenGL 3.1.5 | – Designed to work without errors – Easy to install – Cross-platform |
– Needs to uninstall existing package – Limited control over specific version |
| Upgrading PyOpenGL | – Access to the latest version of PyOpenGL – Easy to download with pip – Quick and straightforward |
– Possible compatibility issues with other packages – May need to reinstall packages that depend on the version |
| Installing Dependencies Separately | – Increased control over specific version – Can install specific packages that are required only |
– Requires more time and effort – Harder to maintain – May not work for some operating systems |
Opinion on Which Method to Use
Based on the comparison table, we can conclude that each method has its advantages and disadvantages. Therefore, the choice of method to use will depend on the specific needs of your project.
If you want a quick and straightforward way to fix the ‘No Handlers Found’ error, you should consider upgrading PyOpenGL. However, if you want better control over dependencies and the packages you install, you should opt for installing them separately.
In cases where both methods are inadequate, you can use the first method of installing PyOpenGL 3.1.5, which is designed to work without errors on various operating systems.
Conclusion
The ‘No Handlers Found’ error can be frustrating when using Python’s OpenGL library. However, there are different ways to fix this error, including installing PyOpenGL 3.1.5, upgrading PyOpenGL, and installing dependencies separately.
It is essential to weigh the advantages and disadvantages of each method to determine which one best suits your project’s needs.

When working with Python’s OpenGL library, you may encounter the No Handlers Found error. Here are some commonly asked questions about how to fix this error:
-
What causes the No Handlers Found error in Python’s OpenGL library?
The No Handlers Found error typically occurs when there is a problem with the PyOpenGL installation or configuration. It usually means that the library cannot find the necessary handlers for the OpenGL functions you are trying to call.
-
How can I fix the No Handlers Found error?
- First, make sure that PyOpenGL is installed correctly and that all dependencies are up to date.
- Verify that your code imports the correct PyOpenGL modules and functions.
- Check that your OpenGL context is set up correctly and that the necessary handlers are loaded.
- You may also need to update your graphics drivers or install additional OpenGL libraries.
-
Are there any known workarounds for the No Handlers Found error?
One possible workaround is to use an alternative OpenGL library such as Pyglet or PyOpenGL-accelerate. These libraries may have different requirements or handlers that are more compatible with your system.
