Native VSCode editor does not work

[ebetica]

Thanks for all your amazing work on Marimo. I'm so excited to see this replace my jupyter notebooks so I can run typechecking and all the goodness of notebooks with python files :)

I'm running the Native VSCode editor for marimo==0.7.8, all I see is a blank screen that says Loading.

The web app works as expected.

Same thing happens to me on

• marimo 0.8.0
• vscode-marimo 0.4.2
• MacOS Sonoma 14.5
• VS Code 1.92.2

Here are the output logs:

@mscolnick I'm still having this issue with vscode-marimo v0.4.8.

[mscolnick]

@mentoc3000, do you see any errors in the extension logs?

[mentoc3000]

I do not. Here are my steps to reproduce:

1. Open empty directory in VS Code
2. Run command "marimio: Create new marimo notebook"
3. Name it whatever

I get that loading screen above that never resolves. My logs are below:

I am able to use the extension to launch the marimo server which I then access via the browser, though.

@mscolnick I am facing the same issue when I attempt to "Open as VSCode Notebook".

When I attempt to "Start in marimo editor", the following message appears: Error running command marimo-explorer.edit: fetch failed. This is likely caused by the extension that contributes marimo-explorer.edit.

My marimo version is 0.9.21

[cotucotudu]

@mscolnick I face exactly what I described in my previous comment with marimo 0.9.27 :(

[mentoc3000]

@mscolnick I propose that this issue be reopened. #41 didn't resolve the issue as far as I can tell.

[gabrielgrant]

yup, also still having this issue:

$ /home/gabriel/marimo-env/bin/python -m marimo --version
0.9.34

[mscolnick]

Does stopping and restarting the server fix this? Can you verify the server is healthy through the Command Palette marimo: Show marimo status (and the bottom line)

[gabrielgrant]

@mscolnick marimo server seems to be running fine -- I'm able to use it through the browser

Not sure if this is actually an issue, but when I try to open the notebook, I see the following output from the marimo extension (Bottom pane > Output > Marimo):

and the following toast message:

[jediwarpraptor]

Is this just dead? Does it work for anyone? It has to work for someone right?

[akshayka]

@jediwarpraptor and others

We're actively rewriting our extension to provide a native experience for marimo notebooks, similar to what you may be used to when using Jupyter in VS Code. It isn't the most straightforward task because marimo is different from the traditional notebooks that VS Code was designed around, but we're making good progress. We'll write back when our rewrite is ready for testing. In the meantime, we recommend using marimo from the command line (docs). Thanks for your patience!

Hi, we've launched a new VSCode extension at https://github.com/marimo-team/marimo-lsp (readme). It may mean this issue is resolved or no longer applicable. If the issue still exists, please file the issue on over on the new Issues page.
