# MNIST

## Tensorflow examples using MNIST.  

**How to Install TensorFlow using pip**  

https://www.tensorflow.org/install/install_linux#determine_how_to_install_tensorflow  

Tested on cs50.io:  

`sudo pip install -U pip`  

`sudo pip install tensorflow`

**MNIST For ML Beginners**  

[softmax.py](https://github.com/EN10/MNIST/blob/master/softmax.py) from https://www.tensorflow.org/get_started/mnist/beginners  

Report Accuracy [print.py](https://github.com/EN10/MNIST/blob/master/print.py) 

**TensorBoard Demo**  

[board.py](https://github.com/EN10/MNIST/blob/master/board.py) TensorBoard Image [image.py](https://github.com/EN10/MNIST/blob/master/image.py)  

https://www.tensorflow.org/get_started/summaries_and_tensorboard  

needs to run in python before tensorboard  

`python board.py`  

`tensorboard --logdir=/tmp/mnist_logs --port 8080`  

tensorboard defaut port 6006 may not be open  

e.g. https://cicai-eniof.cs50.io

**Predict from Image**  

[predict.py](https://github.com/EN10/MNIST/blob/master/predict.py)

requires :  

`sudo pip install --upgrade scipy`  

`sudo pip install pillow`  

based on [softmax.py](https://github.com/EN10/MNIST/blob/master/softmax.py) 

L25 based on [cnnPredict.py](https://github.com/EN10/KerasMNIST/blob/master/cnnPredict.py) L3-11  

trained on `mnist.train.images[0]` vs image `imread('test3.png',mode='L')`  

[expert.py](https://github.com/EN10/MNIST/blob/master/MoreExamples/expert.py) from https://www.tensorflow.org/get_started/mnist/pros  

**Remove Tensorflow Warning**  

disable "cpu_feature_guard":  

`export TF_CPP_MIN_LOG_LEVEL=2`
