No output in Jupyter with Plots and GR

dlfivefifty commented 6 years ago

I don't see any output in the attached. It works fine without the @manpulate for.

Updating IJulia fixed it.

I think it's very brittle: it stopped working again.

Unfortunately WebIO (on which this is based) seems to be having some hiccups lately when used from a notebook. A known issue is that it's not robust to refreshing the page. There is a massive effort to make it more robust at https://github.com/JuliaGizmos/WebIO.jl/pull/211 and a future plan to write a proper Jupyter Lab / Notebook extension which would make it much more solid and reliable.

I'm not seeing any widgets in Jupyter, using Julia 1.0.2, using Interact. All packages up to date. Plots (Plots/pyplot()) working OK.

(a) Is this still broken or (b) Am I doing something wrong?

If (a) Any news, when? else (b) What am I doing wrong?

Thanks.

Could you make sure all dependencies are at their latest release:

(v1.0) pkg> add WebIO@0.6.1
(v1.0) pkg> add InteractBase@0.8.1

Things are supposed to be working, if they don't work in your case it'd be useful to post your versioninfo, what code you are running and in what setup (jupyter notebook or lab).

Thanks.

Can't add WebIO@0.6.1 or InteractBase@0.8.1 -- incompatible with MeshCat -- MeshCat does not exist -- See error messages below. VersionInfo at bottom.

Code: Examples from Doc, notebook tutorials - none produce any widgets. Have tried Jupyter and JupyterLab (which are working OK otherwise). It does seem to work OK in Atom.

Looks like MeshCat prevents you from installing WebIO 0.6 (which could potentially resolve your issue) as it isn't yet compatible with it. The issue to track that compatibility is https://github.com/rdeits/MeshCat.jl/issues/71.

Even though you don't have MeshCat directly installed you probably have installed some package that depends on it (I imagine it must be something from JuliaRobotics). To test that WebIO 0.6 fixes that issue you can either try and remove those packages, or create a separate environment using Pkg, add WebIO 0.6.1 there and test if things work.

Indeed, I have RigidBodyDynamics installed & it uses MeshCat. Guess I'll have to figure out how to create separate environments ... Thanks for your help.
