OpenGL_accelerate is missing: a Python accelerator is not a graphics-driver repair

Scope and symptoms

Rendering nodes can depend on a Python binding, an acceleration extension and a usable graphics context. Locate the failing layer before changing packages or graphics settings.

Search fragments; wording and context vary:

No module named 'OpenGL_accelerate'
No module named 'OpenGL'

Source-supported context

The PyOpenGL-accelerate project describes an acceleration component for PyOpenGL. It is not an operating-system graphics driver and does not by itself establish that a process can create the required rendering context. V04-OPENGL

Distinguish these cases

1. PyOpenGL itself is missing or installed in a different interpreter.

2. The node requires OpenGL_accelerate but no matching native acceleration extension is available in its environment.

3. Imports work and the failure occurs while creating a context under a particular display, remote-desktop or headless configuration.

Suggested diagnostic sequence

This sequence is editorial guidance, not a diagnosis of your machine.

1. Preserve the exception chain and distinguish the two import names. Establish whether acceleration is mandatory for this node or merely optional.

2. For an import failure, align the documented binding and accelerator versions with the Python and platform tags in the correct environment.

3. For a context failure after import, check the node's window, display-server or offscreen-backend requirements. Reinstalling the same Python library is not a test of those requirements.

4. Run the node author's smallest rendering scene and verify context creation and one output frame. Record whether the run is local, remote or headless before restoring the full workflow.

Completion checks

Required imports succeed, the actual rendering context is created and the minimal scene produces output. Seeing a GPU name is insufficient.

Limits and cautions

There is no universal driver replacement or environment-variable switch that makes all rendering backends interchangeable. Follow the selected backend's deployment requirements.
