I used to use the IPython bridge regularly, back before they renamed 
IPython to Jupyter. I haven't touched recent versions.

The fact that this doesn't work for you *now *is potentially the result of 
*code 
rot;* with enough changing in the IPython/Jupyter API to finally(? 
surprised it didn't happen earlier) break the bridge. I doubt anyone has 
touched this bridge code in a while. Ville is for the most part long gone. 
I reached out to him a couple years back and while he responded and was 
cordial his memory of events wasn't good enough to move my issue forward.

I'm not saying that you need to abandon your efforts but unless somebody 
else chimes in you may not receive additional guidance. 

Firstly, however, try to determine if it's worth your time.

The IPython bridge doesn't buy you much. It gave me the ability to use 
IPython's interactive REPL on some of Leo's internals. Most importantly it 
let me view object structure using auto-completion to dig down into various 
objects. This was helpful when developing some plugins. You can most likely 
do similar investigations via Leo scripting, Edward is a wizard at this 
type of stuff and I'm sure has recipes for any type of Leo introspection 
you might want to do. 

If Leo is missing anything it's not necessarily IPython/Jupyter integration 
as is often requested but in general a terminal/console like REPL linked to 
its internals.

Perhaps you should let us know what you want to do with the bridge before 
spending a lot of time trying to get it to work. I would say there is only 
small chance it's going to aid your efforts.
