# TensorFlow Examples
This tutorial was designed for easily diving into TensorFlow, through examples. For readability, it includes both notebooks and source codes with explanation, for both TF v1 & v2.
It is suitable for beginners who want to find clear and concise examples about TensorFlow. Besides the traditional 'raw' TensorFlow implementations, you can also find the latest TensorFlow API practices (such as `layers`, `estimator`, `dataset`, ...).
**Update (08/17/2019):** Added new [TensorFlow 2.0 examples](tensorflow_v2)! (more coming soon).
*If you are using older TensorFlow version (0.11 and under), please take a [look here](https://github.com/aymericdamien/TensorFlow-Examples/tree/0.11).*

## TensorFlow 2.0
The tutorial index for TF v2 is available here: [TensorFlow 2.0 Examples](tensorflow_v2).
## Dataset
Some examples require MNIST dataset for training and testing. Don't worry, this dataset will automatically be downloaded when running examples.
MNIST is a database of handwritten digits, for a quick description of that dataset, you can check [this notebook](https://github.com/aymericdamien/TensorFlow-Examples/blob/master/notebooks/0_Prerequisite/mnist_dataset_intro.ipynb).
Official Website: [http://yann.lecun.com/exdb/mnist/](http://yann.lecun.com/exdb/mnist/).
## Installation
To download all the examples, simply clone this repository:
```
git clone https://github.com/aymericdamien/TensorFlow-Examples
```
To run them, you also need the latest version of TensorFlow. To install it:
```
pip install tensorflow
```
or (with GPU support):
```
pip install tensorflow_gpu
```
For more details about TensorFlow installation, you can check [TensorFlow Installation Guide](https://www.tensorflow.org/install/)
## More Examples
The following examples are coming from [TFLearn](https://github.com/tflearn/tflearn), a library that provides a simplified interface for TensorFlow. You can have a look, there are many [examples](https://github.com/tflearn/tflearn/tree/master/examples) and [pre-built operations and layers](http://tflearn.org/doc_index/#api).
