CUDA is problematic. There is no package for CUDA in the official Guix channels, because it is non-free software. There is a patch for a Tensorflow package, which is built without GPU support (because that requires CUDA), but it hasn't been merged yet, because it isn't really pretty. (I didn't use Bazel to build Tensorflow, because Bazel depends on dozens of Java archives that cannot easily be built exclusively from source.) You can use Nix as an additional package manager on top of a Guix system, of course, but this might not be as satisfying as using one package manager exclusively.
