[SETUP] Lux defaults to Pandas when there are no valid actions defined.

C:\ProgramData\Anaconda3\lib\site-packages\IPython\core\formatters.py:345: UserWarning: Lux defaults to Pandas when there are no valid actions defined.

1. install lux according the document

pip install lux-api

# active Jupyter notebook extension
jupyter nbextension install --py luxwidget
jupyter nbextension enable --py luxwidget

1. run the demo code from readme.md

import lux
import pandas as pd

df = pd.read_csv("https://raw.githubusercontent.com/lux-org/lux-datasets/master/data/college.csv")
df

and then I cannot get the Toggle Pandas/Lux button, and see below warning message

C:\ProgramData\Anaconda3\lib\site-packages\IPython\core\formatters.py:345: UserWarning:
Lux defaults to Pandas when there are no valid actions defined.

please tell me what I am doing wrong, thanks

Hi @jonozw, Yes I think the first warning message is likely caused by df.head(), since the dataframe is not big enough to generate recommendations. It is great to hear that this is working for you now. I’ll close this issue for now, feel free to let us know if there are any issues and questions that come up!

it worked…

1. at the begining, I install lux with pip, then I got the error message.
2. I modify the code form df->df.head()
3. I uninstall the lux with pip and reinstall it with conda
4. modify the code to df again
5. it worked…

I am not sure whether or not the first error message was caused by df.head()…

but now it worked, I like this project, thanks:)
