AttributeError: 'ImFontAtlas' object has no attribute 'get_tex_data_as_rgba32' when running minimal example #875
Description
I'm trying to run the minimal example from the docs, but it raises an AttributeError related to ImFontAtlas.
Code causing the error:
import fastplotlib as fpl
import imageio.v3 as iio
# create a `Figure`
fig = fpl.Figure()
# read data
data = iio.imread("imageio:astronaut.png")
# add image graphic
image_graphic = fig[0, 0].add_image(data=data)
# show the plot
fig.show()
if __name__ == "__main__":
fpl.run()Full output from script
No config found!
EGL says it can present to the window but not natively
Max vertex attribute stride unknown. Assuming it is 2048

AttributeError: 'imgui_bundle._imgui_bundle.imgui.ImFontAtlas' object has no attribute 'get_tex_data_as_rgba32'Steps to reproduce:
-
Create a new virtual environment with Python 3.13:
python3 -m venv venv source venv/bin/activate -
Install fastplotlib with notebook and imgui support:
pip install -U "fastplotlib[notebook,imgui]" -
Install imageio:
pip install imageio
-
Run the example script above with Python 3.
Environment:
-
OS: Ubuntu 24.04.2 LTS (Observed a similar issue on Windows as well, anaconda environment was used there)
-
Python: 3.13
-
fastplotlib version: 0.5.0
-
Could this be a compatibility issue with the version of
imguiorimgui_bundlecurrently installed? -
Would appreciate any pointers on required
imguiversions or dependencies.
