## README

# Process from training with estimator to serving with flask

* Dataset: MNIST dataset from *Keras*
* Training Method : Tensorflow Estimator
* One of the MNIST datasets is randomly selected to show the predicted result and label.

## File explaination

* modeling.py : make model for tensorflow estimator
* train.py : tensorflow training process
* eval.py : evaluate tensorflow estimator model based on train.py
* export.py : export freeze model from model made by train.py
* serving_flask.py : serving freeze model with flask method

## Requirements

* tensorflow==1.14.0
* numpy
* flask
* flask-restful

## Command line

```
python train.py ## training
python eval.py ## evaluate
python export.py ## export model
python serving_flask.py ## serving by flask, you have to edit line 17(export file path)
```

## Serving and Check by requests module
