 In the future it would be advantageous to implement an automated way of keep versions synchronised across files e.g. https://github.com/pre-commit/pre-commit/issues/945#issuecomment-527603460 or preferably parsing `.pre-commit-config.yaml` and using it to `pip install` requirements (see discussion here: https://github.com/brian-team/brian2/pull/1449#issuecomment-1372476018).
