A few months ago I work on a plugin for supporting 'cells' in a regular .py file
I was hoping somebody might give input or comment on its usefulness: https://github.com/UIUC-SINE/ipython-cells
Hi, I am running into an error with cython code and the jupyter kernel ends up restarting itself.. I don't see where the actual error happens, don't see a core file and not sure how to debug further
anyone has any suggestions?

Hello, can I embed ipython in an async program? can't seem to find any docs on it. I've tried:
import nest_asyncio
nest_asyncio.apply()
IPython.embed(using='asyncio')with no luck 😐️
An ipython backend is running on one machine A. This backend receives commands from a user on another machine B, sends them to A for execution, and then returns the results to B. The program running on the other machine B is a pyqt5 GUI that can type strings, but machine B cannot install anything ipython related. What programming interface should the program on machine A call to implement? Or an example of the relevant code.
That's potentically a big task, but the main core function for evaluating code is exec. What 'results' might be is tricky for exec.
IPython's implementation is mostly here but it has lots of handling of different async situations that you probably don't need. Other things to consider include a persistent namespace or not, etc.
Hello! I'm seeing an issue with my IPython setup on Mac, where attempting to use await with an async command results in the following error:
648
649 if self._local._loop is None:
--> 650 raise RuntimeError('There is no current event loop in thread %r.'
651 % threading.current_thread().name)
652
RuntimeError: There is no current event loop in thread 'MainThread'.I've traced it to the fact that the following call always errors out:
import asyncio
asyncio.get_event_loop()---------------------------------------------------------------------------

It could be reasonable to define a metadata field for this use case
