You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false HEAD is now at 2b4bc6a fix: add blank line before closing fence in changelog doctest [rtd-command-info] start-time: 2026-06-05T15:05:31.751668Z, end-time: 2026-06-05T15:05:31.791553Z, duration: 0, exit-code: 0 cat .readthedocs.yml # .readthedocs.yml # Read the Docs configuration file # See https://docs.readthedocs.io/en/stable/config-file/v2.html for details # Required version: 2 build: os: ubuntu-24.04 tools: python: "3.11" apt_packages: - graphviz jobs: post_install: - pip install --extra-index-url https://test.pypi.org/simple/ pennylane-catalyst --pre # torch version must match pyproject.toml [dependency-groups] docs - pip install 'torch~=2.9.0' --index-url https://download.pytorch.org/whl/cpu - pip install --group docs # Build documentation in the docs/ directory with Sphinx sphinx: configuration: doc/conf.py # Build documentation with MkDocs #mkdocs: # configuration: mkdocs.yml # Optionally build your docs in additional formats such as PDF and ePub formats: - htmlzip # Optionally set the version of Python and requirements required to build your docs python: install: - method: pip path: .
