Use the `--trusted-host` option with pip to ignore SSL errors: `pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org tensorflow` 4. Try installing the package with `conda` instead of `pip` 5. Update your SSL certificate bundle by downloading the latest version from the certifi package: `pip install --upgrade certifi` 6. If you are behind a corporate firewall, contact your IT department to check if there are any restrictions on SSL connections. If none of the above solutions work, please provide more details about your system and the error message for further assistance.
