Comment 8 for bug 1611523

I'd like to add big +1 to the proposed solution. As ibus is tool provided by the system, it SHOULD use the system python3 or anything wrong can happen.

It's likely to have user's own python3 interpreter if you're seriously working on machine learning field (e.g. pyenv and virtualenv), and I strongly believe Ubuntu (or other linux distros) shall give the freedom to the users, including installing user local python interpreter.
