12**TensorFlow** is an open source software library for numerical computation
13using data flow graphs. The graph nodes represent mathematical operations, while
14the graph edges represent the multidimensional data arrays (tensors) that flow
15between them. This flexible architecture enables you to deploy computation to
16one or more CPUs or GPUs in a desktop, server, or mobile device without
17rewriting code. TensorFlow also includes
18[TensorBoard](https://github.com/tensorflow/tensorboard), a data visualization
19toolkit.
20
21TensorFlow was originally developed by researchers and engineers
22working on the Google Brain team within Google's Machine Intelligence Research
23organization for the purposes of conducting machine learning and deep neural
24networks research.  The system is general enough to be applicable in a wide
25variety of other domains, as well.
26
27TensorFlow provides stable Python and C APIs as well as non-guaranteed backwards
28compatible API's for C++, Go, Java, JavaScript and Swift.

33
34## Installation
35
36To install the current release for CPU-only:
37
38```
39pip install tensorflow
40```
41
42Use the GPU package for CUDA-enabled GPU cards:
43
44```
45pip install tensorflow-gpu
46```
47
48*See [Installing TensorFlow](https://www.tensorflow.org/install) for detailed
49instructions, and how to build from source.*
50
51People who are a little more adventurous can also try our nightly binaries:
52
53**Nightly pip packages**
54* We are pleased to announce that TensorFlow now offers nightly pip packages
55under the [tf-nightly](https://pypi.python.org/pypi/tf-nightly) and
56[tf-nightly-gpu](https://pypi.python.org/pypi/tf-nightly-gpu) project on pypi.
57Simply run `pip install tf-nightly` or `pip install tf-nightly-gpu` in a clean
58environment to install the nightly TensorFlow build. We support CPU and GPU
59packages on Linux, Mac, and Windows.
60
61#### *Try your first TensorFlow program*
62
63```shell
64$ python
65```
66
67```python
68>>> import tensorflow as tf
69>>> tf.enable_eager_execution()
70>>> tf.add(1, 2).numpy()
713
72>>> hello = tf.constant('Hello, TensorFlow!')
73>>> hello.numpy()
74'Hello, TensorFlow!'
75```
