[Issue] Using lux on Databricks

[pbezz1]

I'm trying to use the lux library in a Databricks notebook but I'm getting this warning and error after the df.intent statment:

Out[10]: /databricks/python/lib/python3.8/site-packages/IPython/core/formatters.py:918: UserWarning: Unexpected error in rendering Lux widget and recommendations. Falling back to Pandas display. Please report the following issue on Github: https://github.com/lux-org/lux/issues

Hi @pbezz1, Thank you for reporting this issue! Could you share the code and data you used to help us reproduce and debug this issue?

[pbezz1]

In a Databricks environment:

1. create a new notebook
2. Enter the following script:

!pip install lux

import pandas as pd import lux

Load dataset

df = pd.read_csv("data/abcdefg.csv")

df.intent = ['col1','col2'] df

The above error is shown.

Hi @pbezz1, What does the data/abcdefg.csv look like? Do you mind sending a sample? I believe this is an issue that is caused by Lux based on the dataset, but not something specific to Databricks.
