logistic-regression example fails #4

Closed azarafrooz closed 6 years ago

This is so good. Thank you for all the efforts you have put into this. I am newbie to Clojure and I was searching for something close to Pytorch spirit and I couldn't get happier finding your codes. Thank you for that!

I was giving your logistic regression example a try and I keep getting some errors. It is highly possible that I am doing something wrong but if you happened to have an idea what might cause these errors, I would appreciate if you could let me know.

Ah, the fix was trivial. num-classes option was missing from the example. Just add it to cli-options: ["-c" "--num-classes NUM" "Number of classes" :default 5 :parse-fn #(Integer/parseInt %)]
