python: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by python)

This error message means that your version of Python requires a higher version of the GNU C library (GLIBC) than what is currently installed on your system. To resolve this issue, you can either upgrade your GLIBC version or install a compatible version of Python.

To upgrade your GLIBC version, you can try updating your system's package manager and then running the following commands:

sudo apt-get update
sudo apt-get upgrade libc6

If upgrading is not an option, you can install a compatible version of Python that is compatible with your current GLIBC version. You can download the appropriate version of Python from the official Python website and install it manually.

Alternatively, you can use a package manager like conda or virtualenv to create a virtual environment for your Python project, which will allow you to install a specific version of Python and its dependencies without affecting your system's global configuration.
