pingles / bandit Goto Github PK

Hi,
Running the first code snippet in README.md, I (ahem) ran into a little hitch.
I entered the forms in a leiningen 2.3.4 repl.

user=> (ns mybandit.core)
nil
mybandit.core=> (load "core")

And got the response:

CompilerException java.lang.RuntimeException: No such var: a/mk-arms, compiling:(mybandit/core.clj:9:11) 

In my core.clj, I had:

(ns mybandit.core 
(:require 
[clj-bandit.arms :as a] 
[clj-bandit.algo.epsilon :as e]))

...

;; the rest of the code in README.md

If I repeat the actions in a repl, as opposed to loading core.clj, the call a/mk-arms causes the same runtime exception as above.

(def arms 
(a/mk-arms :arm1 :arm2 :arm3 :arm4 :arm5))

I replaced it with the exact same implementation of mk-arms in arms.clj

;; in core.clj, right after the namespace definition.
(defn mk-arms [& names] 
 (apply sorted-map (interleave names (map a/mk-arm names))))

(def arms (mk-arms :arm1 :arm2 :arm3 :arm4 :arm5))
...

Which, when ran like this, works well just as the recipe describes. Have you seen this issue anywhere else?

Hey,

Thanks for sharing this, While running this code as you mentioned in README.md I'm getting stack overflow error while running softmax algorithm using simulation.clj code.

Here is error message,

java.lang.StackOverflowError: null
Random.java:532 java.util.Random.nextDouble
Math.java:773 java.lang.Math.random
core.clj:4515 clojure.core/rand
softmax.clj:33 bandit.algo.softmax/select-arm
softmax.clj:33 bandit.algo.softmax/select-arm

Could you please help me resolving this error?
