Hey, I am getting “non-deterministic” behaviour in my implementation using core.matrix and I don’t understand why (there is nothing purposely introducing randomness). Specifically on some runs the dimensions of matrices are wrong and thus computation fails with an exception. On the next run though it might be working again. This does not happen too rarely, I would say ~20-30% of the times it fails. Haven’t yet spent too much time on trying to figure this out but I am wondering if anyone ever saw something like that.
