How to launch IPython while showing line numbers at the prompt?

I launch IPython in a script via: start_ipython(config=cfg) . cfg currently consists of modifications to HistoryAccessor.hist_file, InteractiveShell.banner1... but I can't find anything in the documentation which relates to line numbers at the prompt. Currently, the prompt appears without line numbers as shown. IPython 7.2.0

If I run IPython from the command line (as opposed to from the above script), the line numbers appear as expected

    In the second case IPython is processing the input and output; it's the interactive shell. In the first case, IPython is a module that you've imported. Input/output (the REPL loop) is still the basic python one. You can access some IPython functions with IPython.... syntax, just as you would with any other imported module, but it isn't acting as an interactive shell.

  • ipython.readthedocs.io/en/stable/interactive/… - shows how to start the interactive IPython session after the import. IPython.start_ipython(argv=) or IPython.embed().

  • @hpaulj Perhaps I wasn't clear from the example. The prompt >>> was after I had already run start_ipython. I only got >>> and no lines numbers. (The text import IPython was simply for purposes of the screenshot so I could print out the version of IPython being used).
