Error. Perspective could not render the data

[MarcSkovMadsen]

Describe the bug

When I try to open a parquet file with the perspective-parquet viewer in my JupyterHub I get Error. Perspective could not render the data.

To Reproduce

• add perspective-parquet to the requirements of your JupyterHub base environment
• restart the server
• upload a parquet file
• right click the parquet file, select Open With, Perspective-Parquet.
• See the error

We've tried different parquet files (small, large) without success. It works for csv files.

Expected behavior

It opens without issues

Screenshots

Desktop (please complete the following information):

• OS: Windows
• Browser edge
• Version Version 125.0.2535.92 (Official build) (64-bit)

The JupyterHub is running inside linux docker container on kubernetes

perspective-parquet==0.1.2

[MarcSkovMadsen]

If I look in the browser console I see

ps. Thanks very much for this package. Its just another step to make it as easy to work with data in Jupyter/ Python as in Excel.

[timkpaine]

That error usually occurs when e.g. your python-side perspective is not aligned with js-side perspective. What version of perspective-python is present in the kernel? Actually I don't think I have python-side perspective in this extension, but perhaps you have a version of @finos/perspective-jupyterlab extension also installed?

[MarcSkovMadsen]

I don't think I have @finos/perspective-jupyterlab installed. What I have installed is below

I am facing same exact issue when trying to open .parquet file with perspective-parquet: 'Error. Perspective could not render the data'

I am using:

• perspective-parquet==0.1.2
• perspective-python==2.10.1
• OS: Ubuntu 22.04.2-LTS
• JupyterHub & Jupyterlab 4.1.5

My work-arround now is to convert parquet to arrow, and use perspective-arrow, which works very well.
I hope perspective-parquet can be fixed as it will remove this hastle

thanks!
