TensorFlow is like Numpy, only it is capable of working symbolically and can work more easily with your GPU in a highly parallel manner. For those two reasons, it is vastly superior to numpy for tasks like deep learning / machine learning.
Theano is another symbolic numerical library, coming before TensorFlow, though TensorFlow has seemingly gained more popularity and people have more general faith in it.
