@pipopopo assuming that you have setup your environment as recommended in CONTRIBUTING.md and the Wiki, you can run both pytest and flake8 in the root of your repo to ensure that you have no errors. You can also run make clean html_debug in the docs subdir to verify that your docstrings are correct and you can review your generated docs in docs/_build/html/index.html. If all of these are satisfactory then the CI tests are more likely to pass when you commit your changes. More info on documentation requirements and testing are available in the Core docs.
