##tensorflow简单介绍：
TensorFlow? is an open source software library for numerical computation using data flow graphs.https://www.tensorflow.org/
TensorFlow是谷歌基于DistBelief进行研发的第二代人工智能学习系统，其命名来源于本身的运行原理。Tensor（张量）意味着N维数组，Flow（流）意味着基于数据流图的计算，TensorFlow为张量从图象的一端流动到另一端计算过程。
选择virtualenv install的方法；TensorFlow支持CNN、RNN和LSTM算法，这都是目前在Image，Speech和NLP最流行的深度神经网络模型。
