Why do mo.ui.batch & mo.ui.array clone their contained elements?

batch/array both clone their elements. Why is that needed? What would happen if an UIElement with children wouldn't do that?

Controlling output of long-running process?

getting the output object from a cell, in which we append the output

I have a table from which I want to select some values, and use this to download attachments, zip them, then present a download button. The process takes time, so I tried using mo.lazy to show a spinner, but it doesn't update more than once, when it's inside an accordion. Therefore, I tried hacking my own solution using the output module. However, it struck me that it's not possible to get the the output object from a cell. I'm thinking something like ```spinner=mo.status.spinner() mo.output.append(spinner) _download_attachments = new_download_attachments_ui(heatpump_table) download_attachments = await _download_attachments()...

Is it possible to use OpenAI Compatible API instead of Copilot for autocompletion?

Hi, the documentation for AI Completion says that we can only use either Copilot or Codeium for autocompletion. Is this still true? Or is there a way to use an OpenAI Compatible Model instead? There is a github issue related to this but hasn't been resolved: https://github.com/marimo-team/marimo/issues/2193...

Real-time collaboration stability?

Hi everyone! I am very excited about the experimental real-time collaboration features that I am trying to use with my university students learning Python! However I am experiencing stability issues: the feature works as expected but after a short while (a few minutes) the remote marimo notebooks are displaying some Failed to save / Failed to fetch, Failed to run / Failed to fetch, errors and new connections are impossible ("Secure connection failed" ; see screenshots). The local notebook is still working properly....

DB Connection SQL Cell not connected to other SQL Cells not linked in dataflow

As you can see in the picture attached from my notebook data flow the cell where I create my DB connection is not linked to the SQL cell below it. This is to be expected because these two cells don't share variables but at the same is wrong because these cells depend on each other for execution. I don't know what a good solution for this is at the moment. I think I suggested in another post to have a DB connection tab on the left side menu, this wouldn't solve this particular issue but might be beneficial. @Myles Scolnick...

How to use local AI model like Llama instead of OpenAI

Has anyone tried using a local API endpoint for an AI assistant instead of the OpenAI API? I have Ollama running on my laptop, along with several models to assist with my tasks. That’s why I want to use this local model instead of relying on Anthropic, OpenAI, or Google. By the way, I’m using Llama and Open WebUI....

GitHub copilot unable to connect when using VSCode port forwarding

When running a marimo notebook locally on my laptop copilot works as it should, but when I use the Visual Studio Code port forwarding feature and I connect to the same marimo notebook using the forwarded address, copilot stops working and I get a websockets.exceptions.InvalidURI: http://localhost:2918/copilot isn't a valid URI: scheme isn't ws or wss. Any idea why this is happening? And how can this be fixed?...
