Simple check list from AllenNLP repo: https://github.com/allenai/allennlp/blob/main/setup.py

To create the package for PyPI.

1. Run `make pre-release` (or `make pre-patch` for a patch release) then run `make fix-copies` to fix the index of the
   documentation.

   If releasing on a special branch, copy the updated README.md on the main branch for the commit you will make
   for the post-release and run `make fix-copies` on the main branch as well.

2. Unpin specific versions from setup.py that use a git install.

3. Checkout the release branch (v<RELEASE>-release, for example v4.19-release), and commit these changes with the
   message: "Release: <RELEASE>" and push.

4. Manually trigger the "Nightly and release tests on main/release branch" workflow from the release branch. Wait for
   the tests to complete. We can safely ignore the known test failures.

5. Wait for the tests on main to be completed and be green (otherwise revert and fix bugs).

6. Add a tag in git to mark the release: "git tag v<RELEASE> -m 'Adds tag v<RELEASE> for PyPI'"
   Push the tag to git: git push --tags origin v<RELEASE>-release

7. Build both the sources and the wheel. Do not change anything in setup.py between
   creating the wheel and the source distribution (obviously).

   For the wheel, run: "python setup.py bdist_wheel" in the top level directory
   (This will build a wheel for the Python version you use to build it).

   For the sources, run: "python setup.py sdist"
   You should now have a /dist directory with both .whl and .tar.gz source versions.

   Long story cut short, you need to run both before you can upload the distribution to the
   test PyPI and the actual PyPI servers:

   python setup.py bdist_wheel && python setup.py sdist

8. Check that everything looks correct by uploading the package to the PyPI test server:

   twine upload dist/* -r pypitest
   (pypi suggests using twine as other methods upload files via plaintext.)
   You may have to specify the repository url, use the following command then:
   twine upload dist/* -r pypitest --repository-url=https://test.pypi.org/legacy/

   Check that you can install it in a virtualenv by running:
   pip install -i https://testpypi.python.org/pypi diffusers

   If you are testing from a Colab Notebook, for instance, then do:
   pip install diffusers && pip uninstall diffusers
   pip install -i https://testpypi.python.org/pypi diffusers

   Check you can run the following commands:
   python -c "from diffusers import __version__; print(__version__)"
   python -c "from diffusers import DiffusionPipeline; pipe = DiffusionPipeline.from_pretrained('fusing/unet-ldm-dummy-update'); pipe()"
   python -c "from diffusers import DiffusionPipeline; pipe = DiffusionPipeline.from_pretrained('hf-internal-testing/tiny-stable-diffusion-pipe', safety_checker=None); pipe('ah suh du')"
   python -c "from diffusers import *"

9. Upload the final version to the actual PyPI:
   twine upload dist/* -r pypi

10. Prepare the release notes and publish them on GitHub once everything is looking hunky-dory. You can use the following
    Space to fetch all the commits applicable for the release: https://huggingface.co/spacmes/sayakpaul/auto-release-notes-diffusers.
    It automatically fetches the correct tag and branch but also provides the option to configure them.
    `tag` should be the previous release tag (v0.26.1, for example), and `branch` should be
    the latest release branch (v0.27.0-release, for example). It denotes all commits that have happened on branch
    v0.27.0-release after the tag v0.26.1 was created.

11. Run `make post-release` (or, for a patch release, `make post-patch`). If you were on a branch for the release,
    you need to go back to main before executing this.
