| **TensorFlow** is an open source software library for numerical computation using |
| data flow graphs. The graph nodes 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 also includes TensorBoard, a data visualization toolkit. |
| |
| 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. |

| |
| ## Installation |
| *See [Installing TensorFlow](https://www.tensorflow.org/get_started/os_setup.html) for instructions on how to install our release binaries or how to build from source.* |
| |
| People who are a little more adventurous can also try our nightly binaries: |
| |
| **Nightly pip packages** |
| * We are pleased to announce that TensorFlow now offers nightly pip packages |
| under the [tf-nightly](https://pypi.python.org/pypi/tf-nightly) and |
| [tf-nightly-gpu](https://pypi.python.org/pypi/tf-nightly-gpu) project on pypi. |
| Simply run `pip install tf-nightly` or `pip install tf-nightly-gpu` in a clean |
| environment to install the nightly TensorFlow build. We support CPU and GPU |
| packages on Linux, Mac, and Windows. |
