unexpected error: 'VegaFusionRuntime' object has no attribute 'set_connection'

[cboettig]

I have the vegafusion packages installed via conda:

vegafusion                2.0.0rc1        py312h63f49a4_0    conda-forge
vegafusion-jupyter        1.6.9              pyhd8ed1ab_0    conda-forge
vegafusion-python-embed   1.6.9           py312h63f49a4_2    conda-forge

I try to call vf.runtime.set_connection but get the error 'VegaFusionRuntime' object has no attribute 'set_connection'

import vegafusion as vf
import pandas as pd
import altair as alt

# Configure DuckDB connection
vf.runtime.set_connection("duckdb")

Produces the error trace:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[2], line 6
      4 import duckdb
      5 # Configure DuckDB connection
----> 6 vf.runtime.set_connection("duckdb")

AttributeError: 'VegaFusionRuntime' object has no attribute 'set_connection'

On Ubuntu 22.04 with python 3.12.7

Hi @cboettig, set_connection is being removed in VegaFusion 2, and you have the 2.0 release candidate installed (Unfortunately, conda is installing the release candidate version automatically).

DuckDB relations (DuckDBPyRelation) are now supported like inline datasets directly (See https://vegafusion.io/v2/posts/2024/2024-11-13_Release_2.0.0.html), so you don't need to set_connection and use table:// URLs. Happy to answer any questions.

[cboettig]

awesome on all fronts. (sorry I didn't notice about conda installing the release candidate by default!)

yup, things are working nicely as expected on 1.6.9, and the automatic support in 2.0 sounds fantastic. really enjoying the altair/vega experience so far and hope to include this in my teaching!

Thanks for the kind words, and that's great to hear you're considering using this ecosystem for teaching.

Cross reference conda-forge/altair-feedstock#58 (comment) where @joelostblom ran into this same kind of issue with the release candidate.
