Sample Code

# Any code that plots an interactive PyVista visualization
import pyvista as pv
sphere = pv.Sphere()

# short example
sphere.plot(jupyter_backend='trame')

# long example
plotter = pv.Plotter(notebook=True)
plotter.add_mesh(sphere)
plotter.show(jupyter_backend='trame')

Description

I am trying to display PyVista interactive plots in a Binder instance, but I get various flavours of failure: it either hangs (displays “Loading …” with a wheel that spins for ever), returns a 424 error in the cell output, or 404 error in the cell output. At the current stage, I encounter Error 404 :
"404 : Not Found
You are requesting a page that does not exist!"

The notebook does work locally.

I set up the Binder instance with the recommended apt.txt and start files as indicated in PyVista’s documentation, section “Running on MyBinder”. I also tried a simpler version of a start file I found in the tutorial.

I did access the Binder instance of the pyvista tutorials, where I found that it does indeed work. I also looked through various forums (SO, Discourse, Github issues, ...) to no avail. I also started a Discourse thread on the Jupyter discourse forum.

Any help appreciated !
