All versions of Python that executed successfully executed. Some versions of Python failed to execute on my machine which appears to be an environment of Python build issue, it is not related to packaging. Succeeded on Ubuntu 24.04 x86Succeeded on Windows 11 x86Failed on Ubuntu 24.04 x86 due to Python not runningFailed on Windows 11 x86 due to Python not running |
