Hi, Have tried downgrading these packages, and continuously getting errors. Does anyone have an env in which they work.

hvplot 0.8.1  
panel 0.10.3  
bokeh 3.7.0  
ImportError: cannot import name ‘Box’ from ‘bokeh.models’  
Downgrade Bokeh  
hvplot 0.8.1  
panel 0.10.3  
bokeh 2.4.0  
“ValueError: ClassSelector parameter None value must be an instance of (function, tuple), not \<function size at 0x7fe354743630\>.”

Rather than downgrading, can you upgrade all of them?

Also, for future reference, this question is probably better suited in the [HoloViz Discourse](https://discourse.holoviz.org/).

Panel 0.10.3 is quite old–the current version is 1.6.1.
