Hey Jack,

I'm very new to rust and still don't know how to attack build issues. Can you help me out with that one? I don't understand well why its not working, although the ScopedPool seems to be implemented in the threadpool lib as pub struct ScopedPool<'pool> : https://github.com/rust-lang/threadpool/blob/master/src/lib.rs

Hey swiesend,

I think the problem is that since I last update this, scoped threads were discovered to be unsound and so have been marked as unstable again so won't compile. The fix would be to replace the ScopedPool which I'll do as soon as I have time, hopefully by tomorrow.

Jack

In the IRC channel they told me that I just have to add the scoped-pool feature in the dependencies like this:

[dependencies.threadpool]
version = "0.1"
features = ["scoped-pool"]

So that would only be a temporary solution?

jackm321 commented 9 years ago

I don't think that will work because scoped is still not allowed in beta. I tried that and got error: unstable feature...this feature may not be used in the beta release channel. It might work on nightly but I'm not sure.

I removed batch training so no multithreading for now but it is building. 26aff11c545c31a8eb39a5b1bb0e81ebf290f7da
