Summary

  • Setup guide and system requirements now say Python 3.10 or newer, available as python3 on PATH, with pip and venv. Before, they said only "Python 3".
  • Added a short prerequisite note to the manual "Run Genvm setup" step, with a python3 --version check.

Why

  • The node install runs python3 from PATH twice (taskfiles/node/scripts/install.sh): once for a small stdlib config helper and once for the GenVM post-install (setup.py).
  • The GenVM post-install needs 3.10+. It uses X | None annotations at module level (modules/install/lib/python/post-install/__main__.py), and the node repo states the same minimum (tests/conformance/genvm/README.md).
  • pip and venv are still needed: post-install creates a venv with pip by default (--create-venv defaults to true).
  • Validators don't need PyYAML. The Python 3.13.3+ minimum is for node developers only, so it isn't in the validator guide.

Summary by CodeRabbit

  • Documentation
    • Updated validator setup requirements to specify Python 3.10 or newer, available as python3 with pip and venv.
    • Added a command to check the Python version during node-software setup.

The GenVM post-install (setup.py) uses Python 3.10 syntax and creates
a venv with pip by default, and the node install calls `python3` from
PATH. State the minimum version and the PATH requirement in the setup
guide and system requirements.

CentOS/RHEL validators may need to translate the generic Python package names before setting up GenVM. This is a bounded documentation issue, and the PR remains mergeable with the distribution-specific correction tracked.

Qualify the package names by distribution.

The OS list includes CentOS, but this line does not qualify python3-pip and python3-venv by distribution. RHEL 9 documents venv through python3.11 -m venv and uses versioned pip package names, so this list may misdirect operators on RHEL-family systems. State the required capabilities separately from distribution-specific package names. (docs.redhat.com)

Folded into #705, so the v0.6 release update is a single docs PR. The CodeRabbit note on package names is addressed there.
