TensorFlow version 1.4 is now publicly available-this is a big update. We are very pleased to announce some exciting new features here and hope you enjoy it.
Keras
In version 1.4, Keras has migrated from Tf.contrib.keras to the core package Tf.keras. Keras is a very popular machine learning framework that contains a number of advanced APIs that can minimize the

Deep Learning Library packages Theano, Lasagne, and TensorFlow support GPU installation in Ubuntu
With the popularity of deep learning, more and more people begin to use deep learning to train their own models. GPU training is much faster than the CPU, allowing models that require one week of training to be completed within one day. This post explains how to install Theano, Lasagne, TensorFlow trained with GPU on Ubuntu14.04.

For any beginner, this is the best choice for machine learning because it provides a simpler way to express neural networks than other libraries. The Keras is written in pure Python and is based on the TensorFlow, Theano, and cntk back end.According to the official websi
