 Check the suggestions below for possible resolutions:
 - The pip index has moved from the initial experimental release! Ensure the correct `--extra-index-url=https://pypi.nvidia.com`
-- Only Python versions 3.9, 3.10, and 3.11 are supported
+- Only Python versions 3.10 and 3.11 are supported
 - RAPIDS pip packages require a recent version of pip that [supports PEP600](https://peps.python.org/pep-0600/){: target="_blank"}. Some users may need to update pip: `pip install -U pip`
