Problem with map reduce tutorial

[jacohend]

I'm only adding some options to executor, and otherwise using a custom model:

    let opts = options!(
        Model: ModelRef::from_path(model_path),
        ModelType: "llama",
        MaxContextSize:  2048_usize,
        NThreads: 12_usize,
        Temperature: 0.7
    );
    let exec = executor!(llama, opts.clone())?;

I'm getting

thread 'main' panicked at 'Cannot block the current thread from within a runtime. This happens because a function attempted to block the current thread while the thread is being used to drive asynchronous tasks.'

thread 'main' panicked at 'Cannot block the current thread from within a runtime. This happens because a function attempted to block the current thread while the thread is being used to drive asynchronous tasks.',

Was wondering if I could gain some insight by a rust wizard into what's wrong.
