The setup.py of `python-package` contains some path resolution magic to find `libxgboost.so` which is needed for the python API. Unfortunately the code is incompatible with Nix as it isn't compatible with the store-based structure for each package and tries to express the location of the shared object with relative paths. The detection in `setup.py` and `xgboost/libpath.py` has been either removed entirely or patched to link to the proper store path of the `libxgboost` build input. See https://hydra.nixos.org/build/77702715 for further reference.
