Describe the bug Integrate PyGWalker with Shiny-Python following https://github.com/ObservedObserver/pygwalker-shiny/tree/main. But when I change ui.HTML(pyg.walk(df, spec="./viz-config.json", return_html=True, debug=False)), to ui.HTML(pyg.walk(df, spec="./viz-config.json", use_kernel_calc=True, return_html=True, debug=False)), bug happens. and also there is no data in Data Tab。 Without the option: “use_kernel_calc=True”，the program runs normally.

To Reproduce Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'

with the option: use_kernel_calc=True

[qingfengwuhen]

another interesting thing is that the program adding the option: “use_kernel_calc=True” runs normally in jupyter

Hi, @qingfengwuhen , thanks for feedback.

Currently, pygwalker does not implement communication feature on Shiny, so it cannot use python kernel for data calculation.

You can use the following code to run on Shiny:

ui.HTML(pyg.to_html(df, spec="./viz-config.json"))

[qingfengwuhen]

im strongly looking forward the support of communication feature on Shiny

In todo-list.

Thanks for supporting pygwalker.
