TensorFlow

TensorFlow is the most popular, and most contributed to, deep learning library. Originally developed by Google Brain for use on Google's own AI products, it was open sourced in 2015 and has since become the standard for deep learning. TensorFlow underlies all of Google's own deep learning based products such as Google Translate and the Google Cloud Platform's machine learning APIs. Google has setup TensorFlow specifically to be parallelized, and as such it performs really well in distributed environments. 

TensorFlow provides APIs for Python, C++, Java, and others; however, in this book we are going to stick to utilizing Python. TensorFlow can be installed from PyPy with the simple: pip install tensorflow.
