Dear ImGui Bundle

1.92.700 verified Mon Apr 27 auth: no python

A comprehensive Python binding for Dear ImGui and associated libraries (ImPlot, ImGuizmo, ImPlot3D, etc.). Version 1.92.700 bundles many C++ GUI libraries into a single pip package. Active development, with releases synced to Dear ImGui upstream.

pip install imgui-bundle

Common errors

error ModuleNotFoundError: No module named 'imgui' ↓

cause Trying to import old standalone 'imgui' package instead of using imgui_bundle.

fix

pip uninstall imgui; pip install imgui-bundle; then use 'from imgui_bundle import imgui'.

error AttributeError: module 'imgui' has no attribute 'Begin' ↓

cause Wrong import: you imported the old python imgui package (which has a different API) instead of the bundle.

fix

Use 'from imgui_bundle import imgui', then call imgui.begin() (lowercase).

error ImportError: cannot import name 'glfw' from 'imgui_bundle' ↓

cause GLFW backend not available on some platforms or not installed with the bundle.

fix

Install glfw via pip or use a different backend (e.g., 'from imgui_bundle import hello_imgui').

Warnings

breaking v1.92.0 font API changes: GetTexDataAsRGBA32() is obsolete. Fonts now rasterized dynamically. Code using manual glyph ranges or font textures must be updated. ↓

fix Remove calls to GetTexDataAsRGBA32() and rely on automatic font scaling.

breaking v1.6.1 ImGuizmo API change: Matrix3/6/16 classes introduced; manipulate() modifies matrices in place. Old code using numpy arrays will break. ↓

fix Use gizmo.Matrix3, Matrix6, Matrix16 instead of numpy arrays. See demo_gizmo.py for migration.

gotcha OpenCV is now optional (since v1.92.601). ImmVision does not require OpenCV. If you relied on OpenCV via ImmVision, you must install opencv-python separately. ↓

fix pip install opencv-python if you need OpenCV functionality.

gotcha Python 3.10 minimum. The library does not support older Python versions. ↓

fix Ensure you use Python 3.10+.

deprecated Old imports like 'import imgui' or 'import glfw' directly are deprecated. Use imgui_bundle submodules. ↓

fix Use 'from imgui_bundle import imgui' etc.

Imports

ImGui
wrong
```
import imgui
```
correct
```
from imgui_bundle import imgui
```
The library is not the same as the old python 'imgui' package. Use 'from imgui_bundle import imgui'.
ImPlot
wrong
```
import implot
```
correct
```
from imgui_bundle import implot
```
ImPlot is bundled; import via imgui_bundle.
glfw
wrong
```
import glfw
```
correct
```
from imgui_bundle import glfw
```
GLFW is bundled and aliased; direct import of 'glfw' may be a different package.

Quickstart

Basic import and version check.

from imgui_bundle import imgui
from imgui_bundle import imspinner
import os
os.environ.get('KEY', '')  # auth check placeholder
print("ImGui Bundle v1.92.700 ready")
