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 6a6f591 Merge branch 'main' into test_pl_meet [rtd-command-info] start-time: 2026-04-29T18:28:37.225417Z, end-time: 2026-04-29T18:28:37.298083Z, duration: 0, exit-code: 0 cat .readthedocs.yml version: 2 sphinx: configuration: doc/conf.py python: install: - method: pip path: . build: os: ubuntu-24.04 tools: python: "3.12" apt_packages: - graphviz jobs: post_install: - pip install --group docs - PL_BACKEND="lightning_qubit" python scripts/configure_pyproject_toml.py && SKIP_COMPILATION=True python -m build - rm -rf ./build && PL_BACKEND="lightning_gpu" python scripts/configure_pyproject_toml.py && SKIP_COMPILATION=True python -m build - rm -rf ./build && PL_BACKEND="lightning_amdgpu" python scripts/configure_pyproject_toml.py && SKIP_COMPILATION=True python -m build - rm -rf ./build && PL_BACKEND="lightning_kokkos" python scripts/configure_pyproject_toml.py && SKIP_COMPILATION=True python -m build - rm -rf ./build && PL_BACKEND="lightning_tensor" python scripts/configure_pyproject_toml.py && SKIP_COMPILATION=True python -m build - python -m pip install ./dist/*.whl [rtd-command-info] start-time: 2026-04-29T18:28:40.776455Z, end-time: 2026-04-29T18:28:50.189514Z, duration: 9, exit-code: 0 apt-get update --assume-yes --quiet Get:1 http://security.ubuntu.com/ubuntu noble-security InRelease [126 kB] Hit:2 http://archive.ubuntu.com/ubuntu noble InRelease Get:3 http://archive.ubuntu.com/ubuntu noble-updates InRelease [126 kB] Get:4 http://security.ubuntu.com/ubuntu noble-security/main amd64 Packages [1985 kB] Get:5 http://archive.ubuntu.com/ubuntu noble-backports InRelease [126 kB] Get:6 http://security.ubuntu.com/ubuntu noble-security/main amd64 Components [25.1 kB] Get:7 http://security.ubuntu.com/ubuntu noble-security/universe amd64 Packages [1498 kB] Get:8 http://security.ubuntu.com/ubuntu noble-security/universe amd64 Components [94.8 kB] Get:9 http://security.ubuntu.com/ubuntu noble-security/restricted amd64 Packages [3491 kB] Get:10 http://security.ubuntu.com/ubuntu noble-security/restricted amd64 Components [157 B] Get:11 http://security.ubuntu.com/ubuntu noble-security/multiverse amd64 Packages [34.2 kB] Get:12 http://security.ubuntu.com/ubuntu noble-security/multiverse amd64 Components [158 B] Get:13 http://archive.ubuntu.com/ubuntu noble/main amd64 Components [665 kB] Get:14 http://archive.ubuntu.com/ubuntu noble/universe amd64 Components [5943 kB] Get:15 http://archive.ubuntu.com/ubuntu noble/multiverse amd64 Components [41.9 kB] Get:16 http://archive.ubuntu.com/ubuntu noble-updates/main amd64 Packages [2355 kB] Get:17 http://archive.ubuntu.com/ubuntu noble-updates/main amd64 Components [237 kB] Get:18 http://archive.ubuntu.com/ubuntu noble-updates/universe amd64 Packages [2142 kB] Get:19 http://archive.ubuntu.com/ubuntu noble-updates/universe amd64 Components [532 kB] Get:20 http://archive.ubuntu.com/ubuntu noble-updates/restricted amd64 Packages [3737 kB] Get:21 http://archive.ubuntu.com/ubuntu noble-updates/restricted amd64 Components [159 B] Get:22 http://archive.ubuntu.com/ubuntu noble-updates/multiverse amd64 Packages [54.1 kB] Get:23 http://archive.ubuntu.com/ubuntu noble-updates/multiverse amd64 Components [888 B] Get:24 http://archive.ubuntu.com/ubuntu noble-backports/main amd64 Packages [49.0 kB] Get:25 http://archive.ubuntu.com/ubuntu noble-backports/main amd64 Components [8177 B] Get:26 http://archive.ubuntu.com/ubuntu noble-backports/universe amd64 Packages [35.6 kB] Get:27 http://archive.ubuntu.com/ubuntu noble-backports/universe amd64 Components [11.4 kB] Get:28 http://archive.ubuntu.com/ubuntu noble-backports/restricted amd64 Components [160 B] Get:29 http://archive.ubuntu.com/ubuntu noble-backports/multiverse amd64 Packages [671 B] Get:30 http://archive.ubuntu.com/ubuntu noble-backports/multiverse amd64 Components [161 B] Fetched 23.3 MB in 4s (6360 kB/s) Reading package lists...
