Polars in Pyodide

Publishing Your Results

Hi,

I am very excited to hear that it is now possible to use Polars with Pyodide and Quarto-Live. This will make me finally switch from Pandas to Polars.

However, I have a problem. When I render a Quarto-Live qmd, I can run all chunks but when I run the chunk that imports Polars, in a browser I get:

No module named 'polars'

I uninstalled all Python versions and installed Python 3.14 (although it looks like Pyodide runs Python 3.13.2), I also uninstalled Positron and reinstalled it, then I upgrade Quarto to 1.8.26.

When the local host is listening the lower bar in Positron says: "Initializing Virtual Environments".

Thank you so much in advance for your help.

Carsten

Below is my code.

import pandas as pd
print("pandas loaded")

import sys
print(sys.version)

import polars as pl
print("pandas loaded")

After long further research, this is what I found out (hope it helps others who come along this post): Polars was included in Pyodide 27, but then taken out in version 28 and not reintegrated in version 29. I hope it gets back into version 30, until then I will wait patiently. Any update is appreciated.
