TensorFlow Simple introduction and installation on CentOS

# #tensorflow简单介绍:

TensorFlow? is a open source software library for numerical computation using data Flow graphs.https://www.tensorflow.org/
TensorFlow is Google's second generation of AI learning systems based on Distbelief, and its nomenclature derives from its own operating principles. Tensor (tensor) means that n-dimensional arrays, flow (flow) means that based on the calculation of the flow graph, the TensorFlow is the calculation process of the tensor from one end of the image to the other.
Choose the Virtualenv install method; TensorFlow supports the CNN, RNN, and lstm algorithms, which are currently the most popular deep neural network models in Image,speech and NLP.
