Support for rendering inside VSCode

[jc9677]

Hi, I'm really looking forward to playing with lonboard but I can't get viz to to render. I've tried the two example notebooks... They render in your Binder and Colab links, but when I try them in local Jupyter, nothing gets displayed but a blank white bar in the cell output. The objects returned from viz seem valid -- I can see coordinates etc when I print them as a string. I assume there might be a widget support issue or something like that. I'm using conda to create env's on a Windows machine. Tried various python 3 versions, tried upgrading/downgrading Jupyter-related packages but no luck so far. Also tried upgrading & downgrading pyogrio, lonboard, pyarrow...

You could look for errors in the browser console (right click and choose inspect to open). Alternatively it could be an issue in your Python-jupyter environment setup. You should also try reloading the page, not just the jupyter kernel, if you haven't done that yet.

The Jupyter logs below are from the cell in question in north-america-roads.ipynb
(map_ = viz(gdf.geometry, width_min_pixels=0.8)
map_ ).

Unfortunately I don't know how to trace the cause. Hoping something stands out for you.

You're not in Jupyter, you're in VSCode. VSCode is not currently supported

[jc9677]

Sorry, I had initially mentioned VS Code while drafting the issue but I reworded things and forgot to put it back in. I did try Jupyter in a dedicated env (not tied to VS Code in any way) and couldn't render there either but that must have been a different problem. I will give it another go outside of VS Code. Thanks Kyle!

anywidget should work in VSCode environments. If i get the chance, i can dig into the devtools to try to see what's going on

[kylebarron]

Actually it looks like it's fixed on main, so it was probably fixed by #199

[kylebarron]

Yep, I can confirm this was fixed by #199. If I rewind before that commit, I get the following error, which is the same as what was described in manzt/anywidget#369.

I'll make a new release sometime this week

Ran into this as well -- had to restart the Jupyter kernel in case anyone else is running into this!

This is the library I've been waiting for!!!
