Answer 1

As a short-term workaround, you have two options:

(1) Create a symlink python in your $PATH that references python3. This can be done in one of several ways:

• Some Linux distros have a python-is-python3 package for that
• Some distros have other "official" ways to do it
• Or you can just sudo ln -s /usr/local/bin/python3 /usr/local/bin/python (or whatever the correct paths are on your system).

(2) You can call gm.py with an explicit Python binary: python3 tools/dev/gm.py

Medium-term, gm.py should be updated to require python3 directly. The fact that it doesn't do so yet is an artifact of the Python2-to-Python3 migration.
