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 your the commit you will make
   for the post-release and run `make fix-copies` on the main branch as well.

2. Run Tests for Amazon Sagemaker. The documentation is located in `./tests/sagemaker/README.md`, otherwise @philschmid.

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

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

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.

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

   twine upload dist/* -r pypitest
   (pypi suggest 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

   Check you can run the following commands:
   python -c "from diffusers import pipeline; classifier = pipeline('text-classification'); print(classifier('What a nice release'))"
   python -c "from diffusers import *"

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

10. Copy the release notes from RELEASE.md to the tag in github once everything is looking hunky-dory.

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.

# Just pass the desired package names to that script as it's shown with 2 packages above.

# If diffusers is not yet installed and the work is done from the cloned repo remember to add `PYTHONPATH=src` to the script above

# pip install -U $(python -c 'import sys; from diffusers.dependency_versions_table import deps; \

# Release checklist
# 1. Change the version in __init__.py and setup.py.
# 2. Commit these changes with the message: "Release: Release"
# 3. Add a tag in git to mark the release: "git tag RELEASE -m 'Adds tag RELEASE for pypi' "
#    Push the tag to git: git push --tags origin main
# 4. Run the following commands in the top-level directory:
#      python setup.py bdist_wheel
#      python setup.py sdist
# 5. Upload the package to the pypi test server first:
#      twine upload dist/* -r pypitest
#      twine upload dist/* -r pypitest --repository-url=https://test.pypi.org/legacy/
# 6. Check that you can install it in a virtualenv by running:
#      pip install -i https://testpypi.python.org/pypi diffusers
#      diffusers env
#      diffusers test
# 7. Upload the final version to actual pypi:
#      twine upload dist/* -r pypi
# 8. Add release notes to the tag in github once everything is looking hunky-dory.
# 9. Update the version in __init__.py, setup.py to the new version "-dev" and push to master
