Which do you think is the best library or tool for Data Science, Machine Learning or Big Data?

Answer 1

scikit-learn is great for most ML applications
tensorflow, mxnet, keras or pytorch (R.I.P. theano 😢) are your choices for deep learning and neural network models.

Answer 2

Oh no, theano exists alright. Just won't be maintained. Google-backed Tensorflow is good. I use keras with tensorflow back-end, as building NN layers is a piece of cake with keras and for prototyping I find it more handy over plain tensorflow.

Answer 3

thanks Kuba...and I didnt know Theano doesnt exist anymore... what do you think about Tensor Flow?
