I followed the guide on nixos wiki GNS3 - NixOS Wiki
i use unstable nixpkgs

configuration.nix:

users.users.myuser = {
        packages = with pkgs; [ 
        gns3-gui 
        ];
};
environment.systemPackages = with pkgs; [
        gns3-server
];

after a while switching between comits in nixpkgs, this commit is the problem

3

opened up an issue Build failure: GNS3, problem with python · Issue #299447 · NixOS/nixpkgs · GitHub
my temporary fix is revert my nixpkgs back a commit

inputs = {
    nixpkgs = {
      url = "github:nixos/nixpkgs/093051473fd84cce950f574e77754353a5731463";#nixpkgs-unstable";
    };

will wait for answer because i have no idea what to do with it
