danieldk's Nix repository

This Nix package repository primarily offers natural language processing and machine learning packages. Most of these packages have a user group that is too narrow to upstream them in nixpkgs.

Supported Nix channels

In principle any modern release of Nix is supported. CI builds of packages are automatically performed on NixOS 19.03. macOS builds are checked semi-regularly. Failing macOS builds are considered to be bugs.

Using the repository

One-off installs

One-off package installs can be performed without configuration changes, using e.g. nix-env:

$ nix-env \
  -f \
  -iA finalfrontier

Adding the repository

If you want to use multiple packages from the repository or get package updates, it is recommended to add the package set to your local Nix configuration. You can do this be adding the package set to your packageOverrides. To do so, add the following to ~/.config/nixpkgs/config.nix:

  packageOverrides = pkgs: {
    danieldk = import (builtins.fetchTarball "") {
      inherit pkgs;

Then the packages will be available as attributes under danieldk, e.g. danieldk.finalfrontier.

Pinning a specific revision

Fetching the repository tarball as above will only cache the repository download for an hour. To avoid this, you should pin the repository to a specific revision.

  packageOverrides = pkgs: {
    danieldk-pinned = import (builtins.fetchTarball {
        # Get the archive for commit baa127b
        url = "";
        # Get the SHA256 hash using: nix-prefetch-url --unpack <url>
        sha256 = "04l7djqsc6qx9bk2ri3jqwpx7vnqviyh65s7aqxk6d06kf89gc4h";
      inherit pkgs;

Binary cache

After each commit, CI uploads builds on the latest stable NixOS to cachix. If you want to use this binary cache, follow the steps described at
