After emerge app-admin/ansible which pulls in dev-python/ipython-5.4.1-r2, I see the following message: * Messages for package dev-python/ipython-5.4.1-r2: * dev-python/sympy for sympyprinting * dev-python/line_profiler for %lprun magic command * dev-python/memory_profiler for %mprun magic command These seems to be just fragments, not clear notifications.
Seems resolved in dev-python/ipython-7.18.1. Closing the bug.
