Problem in using hiplot for streamlit

[shangzTJ]

Hi, I tried to run hiplot/examples/demo_streamlit.py on Windows , I got the following error in web page:

Your app is having trouble loading the hiplot.experiment.hiplot component.

(The app is attempting to load the component from , and hasn't received its "streamlit:componentReady" message.)

If this is a development build, have you started the dev server?
If this is a release build, have you compiled the frontend?
For more troubleshooting help, please see the or visit our ***.

Is this induced by a bug? If not, how can I solve the issue?

Thank you!

Hello - and thank you for opening an issue :)

As it's working on my laptop, I would like to check a few things about your setup:

• What is the exact command you typed to run streamlit on this example?
• How did you install hiplot? (with conda? or "pip install" ?)
• Can you run that for me and give me the output? python -c "import hiplot; print(hiplot.__version__); print(hiplot.__file__)"

Thank you!

Thanks! @danthe3rd

1. The command is streamlit run demo_streamlit.py, and displayed the following information after the web page was opened

Oh I see.
It's the same issue as in #127. I proposed a workaround in the issue - but it's a problem within streamlit - tracking in streamlit/streamlit#1936

[shangzTJ]

It works. Thank you :) @danthe3rd

This should be fixed in streamlit as of the next release (or with streamlit-nightly)
