thanks to all. I'm studying AI, so maybe there will be something good for Julia BUT we are reaching only now good libraries for Python.
They are porting good R libraries, there is Theano, pandas, scikit-learn, pylearn2 etc. With Julia? Let's see but it's a shame we start again :(((
I'm curious. I would like to know if it is worth to learn a new language only for speed reasons or if it's better to hope in improvements in Python... What do you think?
