#TensorFlow

TensorFlow is an open source software library for numerical computation using
data flow graphs.  Nodes in the graph represent mathematical operations, while
the graph edges represent the multidimensional data arrays (tensors) that flow
between them.  This flexible architecture lets you deploy computation to one
or more CPUs or GPUs in a desktop, server, or mobile device without rewriting
code.  TensorFlow was originally developed by researchers and engineers
working on the Google Brain team within Google's Machine Intelligence research
organization for the purposes of conducting machine learning and deep neural
networks research.  The system is general enough to be applicable in a wide
variety of other domains, as well.

# Download and Setup

27 28 29
To install the CPU version of TensorFlow using a binary package, see the
instructions below.  For more detailed installation instructions, including
installing from source, GPU-enabled support, etc., see
30
[here](tensorflow/g3doc/get_started/os_setup.md).

## Binary Installation

34
The TensorFlow Python API supports Python 2.7 and Python 3.3+.
35

36 37
The simplest way to install TensorFlow is using
[pip](https://pypi.python.org/pypi/pip) for both Linux and Mac.

### Ubuntu/Linux 64-bit
44

45
```bash
46
# For CPU-only version
47
$ pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl
48 49 50 51
```

### Mac OS X

52 53 54
```bash
# Only CPU-version is available at the moment.
$ pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl
55 56 57 58 59 60 61 62 63 64
```

### Try your first TensorFlow program

```sh
$ python

>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
65
>>> sess.run(hello)
66 67 68
Hello, TensorFlow!
>>> a = tf.constant(10)
>>> b = tf.constant(32)
69
>>> sess.run(a+b)
70 71 72 73 74
42
>>>

```
