Broken if no Internet Connection Available
Does not work without internet connection; gets stuck in loading screen. (using through pyvista, in a VS Code notebook) I belive the issue is with trame and not pyvista itself?
A clear and concise description of what the bug is. Before submitting, please remove unnecessary sections.
To Reproduce
Steps to reproduce the behavior:
- disable internet connection
- try to plot mesh in pyvista
Code
# disable internet, restart VS Code, create blank .ipynb
import pyvista as pv
pv.Icosahedron().plot()
developer console output:
index-5844b947.js:23 error: Uncaught TypeError: Cannot read properties of null (reading '0')

Expected behavior
I don't think generally a python plotting package should be loading external resources please package all resources. I don't know what it is trying to load? The only thing i can see is that it depends on google fonts which are not available, but i don't see how that is causing the JavaScript error?

Done the following and it worked for me
uv venv -p 3.11
source .venv/bin/activate\n
uv pip install "pyvista[all]"
uv pip install jupyterlab
Turn wifi off
jupyter lab
Execute the following in the cell
import pyvista as pv
pv.Icosahedron().plot()
I can see the 3D view with everything
uv pip list
