The following suggestion is almost certainly overkill and probably more work to set up than simply porting the application to Python 3. On HPC systems, multiple versions of software packages are often installed parallel to the packages provided by the operating system. So the system I work with runs AlmaLinux 8.10, which provides Python 2.7.18 and Python 3.6.8. However, in addition to these version we also have a number of other versions of Python namely: Python/2.7.14-intel-2018a Python/2.7.15-foss-2018b Python/2.7.15-GCCcore-8.2.0 Python/2.7.15-intel-2018b Python/2.7.16-GCCcore-8.3.0 Python/2.7.18-GCCcore-9.3.0 Python/2.7.18-GCCcore-10.2.0 Python/3.6.4-foss-2018a Python/3.6.4-intel-2018a Python/3.6.6-foss-2018b Python/3.6.6-fosscuda-2018b Python/3.6.6-intel-2018b Python/3.7.2-GCCcore-8.2.0 Python/3.7.4-GCCcore-8.3.0 Python/3.8.2-GCCcore-9.3.0 Python/3.8.6-GCCcore-10.2.0 Python/3.9.5-GCCcore-10.3.0 Python/3.9.6-GCCcore-11.2.0 Python/3.10.4-GCCcore-11.3.0 Python/3.10.8-GCCcore-12.2.0 Python/3.11.3-GCCcore-12.3.0 Python/3.11.5-GCCcore-13.2.0 Python/3.12.3-GCCcore-13.3.0 (The suffix after the version refers to the toolchain, the main component of which is the compiler, used to build the software). These are installed using EasyBuild[1] (no Debian package), which allows one to install pieces of (mostly scientific) software plus all dependencies with a single command. The desired version can then be chosen by using Lmod[2] (Debian package: lmod). Like I say, probably overkill for the case here, but possibly useful for someone.
