Old timer here .... wanna make a NN game player. What library should I use? • /r/MachineLearning

I actually started to look for old hard drive where I'd written my own code. But cmon, I know newer widely used library will be better. Googling led to too many options, and a slight feeling of being overwhelmed. I'm pretty much just looking to make a few classification networks. Cross Entropy is my cost function, not MSE.
