Figures don't appear in Jupyter Lab

[limarta]

• are you running newest version? Julia 1.9.2, WGLMakie 0.8.11, IJulia 1.24.2
• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie) yes
• What platform + GPU are you on? M1 Mac. v12.5.
  MWE Steps:

1. Run jupyter-lab

using WGLMakie
Makie.inline!(true)

f = Figure(resolution = (800, 800))
Axis(f[1, 1], backgroundcolor = "black")

xs = LinRange(0, 2pi, 20)
ys = LinRange(0, 3pi, 20)
us = [sin(x) * cos(y) for x in xs, y in ys]
vs = [-cos(x) * sin(y) for x in xs, y in ys]
strength = vec(sqrt.(us .^ 2 .+ vs .^ 2))

arrows!(xs, ys, us, vs, arrowsize = 10, lengthscale = 0.3,
    arrowcolor = strength, linecolor = strength)

f

An example output with no figure below the cell:

Try adding the following snippet before plotting:

using WGLMakie, Bonito

Page(listen_url="localhost")

I see the same with Julia 1.10.4 and these pkg versions.

Status `~/playground/wglmakie/Project.toml`
  [824d6782] Bonito v3.1.2
  [7073ff75] IJulia v1.25.0
  [276b4fcb] WGLMakie v0.10.7

Note that, as has been pointed out by @lazarusA on Slack, it seems to matter which jupyter you use or how you start it. I see no output when using my global jupyter lab (v4.0.11 if that matters). Lazaro does see output if he uses using IJulia; notebook().

Would be great if we could figure out what's going on here. Forcing people to install yet another jupyter installation for WGLMakie to work seems very unfortunate. Also, the jupyter that's auto-installed by IJulia.notebook() doesn't even work for me ("500 : Internal Server Error").

FWIW, Bonito itself seems to work in my setup. Only WGLMakie does not.

bonito_jupyter.mp4

[carstenbauer]

Alright, it seems to be jupyter lab vs jupyter notebook. Using the former I get no/empty output. Using the latter everything works:

wglmakie_jupyter.mp4

The question is why!

[carstenbauer]

Now I’m confused…. it seems to work in jupyter lab now as well… Note: I had to install mamba install jupyter to have jupyter notebook available. Perhaps that installed some things that were necessary on the jupyter end? Wildly guessing here.

(I'm going to take a break now 😄)

Jupyter Lab is a mess :(
See: https://github.com/SimonDanisch/Bonito.jl/blob/master/src/server-defaults.jl#L18-L53
I'ts not easy to figure out the parameters to build up the connection correctly, and it seems to change from time to time.

Using Page(listen_url="localhost") makes it display in both jupyter lab and notebook for me. However, the first time I ran a plot it works but gives the following error message:

Following plots work fine.
