The fact that it only happened to some students was evidence that conda wasn't as hermetically sealed as nix. Conda can be a bit fiddly, it makes life much easier if you specify the required version of python when you create a new environment. >I know that conda lets users do this too, but I don't think that the environments compose as well as they do with nix. Yes, though we find Conda great for most of our use cases, we still have to resort to creating containers.
