WebIO not detected in jupyterlab #315

Do you have more than one version of Jupyter Lab (e.g. one on your system and the one installed by IJulia)? |
|
yes and no: I get the same error on my laptop where I only have |
|
Can you We try to find the best JupyterLab to use; it defaults to the one in your path and if there is none it tries to use the one IJulia installs (if any). |

Glad it worked! WebIO defaults to the first Jupyter in the path (though you can change this by passing in the path to the executable as the first argument) and if it can't find any, it uses the one installed by Conda.jl (as part of IJulia, usually). We're working on documentation to make things as easy as possible too. |

I have this issue in JupyterLab 1.0 It is possible to install the jupyter lab provider extension, however WebIO claims afterwards: I tried uninstalling everything, running jupyter lab clean, and running WebIO.install_jupyter_serverextension and WebIO.install_jupyter_labextension and verifying the jupyter location is correct.

Unfortunately I can't reproduce this. I suspect you might be infected by the previous "bad" (i.e. not-working/buggy) WebIO jupyterlab extension. Can you try nuking conda and see if that fixes things? run(`rm -rf ~/.julia/dev/conda`)

The first one is (probably) because you have Jupyter notebook installed through pip or homebrew. You can specify force_conda_jupyter to make WebIO use the one installed by IJulia (assuming that's how you launch jupyterlab). The second one will require you to upgrade jupyterlab. You should be able to There seem to be some issues with jupyterlab ATM concerning the initial render. Usually refreshing makes things work. |
|
In the first one, this is just a standard install on a new machine, following the IJulia install, so I don't think that is it. If I try to force it, how and to what do I supply the The second one initially seemed fixed by your suggestion, but then on restart, sliders no longer update, as for the first one. |
|
WebIO uses the first WebIO.install_jupyter_labextension(; force_conda_jupyter=true)I don't have a fix for the second other than just "refresh until it works." Hopefully I'll have some time to look into that soon. |

On the third one (macOS Mojave 10.14.6) I no longer get a major error after nuking Then the sliders come appear (WebIO not detected is no longer the issue), but again, they don't update when slid ... Should I open a new issue? |
|
I have the same problem shown in the message above on Ubuntu 18.04. Anyway to fix this problem? Thank you. |
|
@jzazo did you ever get this working? |
|
Well, I was using ECharts.jl to plot some figures and I could not get it to work on Jupyter nor Atom. However it did work using Blink.jl on terminal, and that sufficed to me. Sorry I cannot help, it didn't work for me. |
|
I seem to have made some progress on this, though I'm running Jupyter Lab in a docker container on Debian. For me, the reason none of this was working (Specifically that WebIO couldn't be found) was because I was mounting/using a custom Jupyter config file. It turns out, during the container build, What I've had to do is edit the As a note, I do still get the |
|
I should also add the output of |
Haha what's that? Yeah this situation sounds a bit out of our control. Although running the install command after your Dockerfile is done setting up (like at the very end) should work too. |
|
My thought in posting was less about Docker (because obviously that's not WebIO's problem :P) but more sharing what I found was the hang up. Maybe some of the people for whom this isn't working aren't having the right lines added to their Jupyter Config or perhaps they're overwriting the one created by the WebIO installation procedure without realizing it? |
|
Hello, I'd like to share with everyone the solution that helped me get out of this problem of not being able to use Interact because of the said error: WebIO not detected in jupyterlab After All my troubleshooting, removing and reinstalling Julia, IJulia, Interact and etc, what helped me was as simple as running from "Anaconda PowerShell Prompt (3)" the next code:
NOTE: It doesn't matters if you have it already installed from IJulia, I saw no conflict at the time of using this command. This worked on my case, but I'm not 100% sure that it'll do the same in every case. |
|
May I ask if anyone has found a stable solution to this? I'm on macOS 11.0.1.
But it seems to work fine in command line:
|
|
Can confirm, both Interact.jl and PlotlyJS.jl have the same problem in Windows and Linux. I have been trying for 2 days to sort it :/ It would be nice if documentation could be expanded a little and to include a simple test to debug what may be going on with WebIO and Juypyterlab detecting it. |
|
I know of no solution. I found this so disheartening when dealing with large student groups that I gave up on jupyterlab and moved to Pluto several years ago. For me this proven a highly robust solution to the problem. |
