Hello guys, I would like to try out this library, but ran into a problem with Clojure 1.3, 'lein repl' throws an exception, when:
*user=> (use 'probabilistic-clojure.monadic.demos)* *user=> (test-mixture mixture-mem) * *Trying to find valid trace ...* *Starting MH-sampling.* *IllegalArgumentException No value supplied for key: 0.7 clojure.lang.PersistentHashMap.createWithCheck (PersistentHashMap.java:89)* I am a total beginner with Clojure, if you could provide a at least a hint of how to resolve this - I'd appreciate it. P.S. I am using the "1.3" branch by Jeff, that works with Leiningen. Thanks! - Julius On Sun, Nov 20, 2011 at 6:32 AM, Jeff Rose <ros...@gmail.com> wrote: > Cool!
