If you are pure PURE python, and you have your system dependencies managed properly, then there might not be much point. If you are primarily python but need to add C/C++/BLAS/LAPACK/MKL/Fortran, etc..., at least on linux and macOS, then you are going to want conda or something like it. conda with the conda-forge channel solves much of that. There's other things out there which can solve it, notably Spack, possibly Nix. Or, you reduce the problem space by only building for a single linux and distributing containers, if that works for you.
