I haven't tried anything ipython for a very long time so not sure I can help much. These two lines in the traceback stand out to me though:
File ".\leo\plugins\qt_gui.py", line 1424, in show_tips ModuleNotFoundError: No module named 'leo.core.leoTips' *...later:* Win10 x64, python 3.6.9 in a conda env. python .\launchLeo.py --ipython leoIpython.py: can not import connect_qtconsole leoIpython.py: can not import IPKernelApp Leo 6.3-devel, devel branch, build 8051ecd172 2020-04-05 05:55:36 -0500 Leo worked fine, but no ipython, which isn't surprising because I haven't installed it. pip install notebook python .\launchLeo.py --ipython *Now *Leo locks up like you described earlier. However there's a message in the console: [IPKernelApp] WARNING | Eventloop or matplotlib integration failed. Is matplotlib installed? new_qt_console <subprocess.Popen object at 0x0000015DEFE77DA0> So I pip installed matplotlib and tried again. Leo now does not lock up and appears to functioning normally. The console still complains that matplotlib integration fails though. Here's the last console log: # python .\launchLeo.py --ipython Leo 6.3-devel, devel branch, build 8051ecd172 2020-04-05 05:55:36 -0500 don't forget to launch leo-ver-serv!!! NOTE: When using the `ipython kernel` entry point, Ctrl-C will not work. To exit, you will have to explicitly quit this process, by either sending "quit" from a client, or using Ctrl-\ in UNIX-like environments. To read more about this, see https://github.com/ipython/ipython/issues/2049 To connect another client to this kernel, use: --existing kernel-4816.json [IPKernelApp] WARNING | Eventloop or matplotlib integration failed.
