Docker Installation

Build the image

cd keras-flask-deploy-webapp
docker build -t keras_flask .
docker run -e MODEL_PATH=models/your_model.h5 -p 5000:5000

You can mount your model into the container.

docker run -e MODEL_PATH=/mnt/models/your_model.h5  -v volume-name:/mnt/models -p 5000:5000 keras_flask

Local Installation

Clone the repo

$ git clone https://github.com/mtobeiyf/keras-flask-deploy-webapp.git

Install requirements

$ pip install -r requirements.txt

Make sure you have the following installed:

tensorflow
keras
flask
pillow
h5py
gevent

Run with Python

Python 2.7 or 3.5+ are supported and tested.

$ python app.py

Play

Open http://localhost:5000 and have fun. 😃

Customization

Use your own model

Place your trained .h5 file saved by model.save() under models directory.

Check the commented code in app.py.

Use other pre-trained model

See Keras applications for more available models such as DenseNet, MobilNet, NASNet, etc.

Check this section in app.py.

UI Modification

Modify files in templates and static directory.

index.html for the UI and main.js for all the behaviors

Deployment

To deploy it for public use, you need to have a public linux server.

Run the app

Run the script and hide it in background with tmux or screen.

$ python app.py

You can also use gunicorn instead of gevent

$ gunicorn -b 127.0.0.1:5000 app:app

More deployment options, check here

Set up Nginx

To redirect the traffic to your local app. Configure your Nginx .conf file.

server {
    listen  80;

    client_max_body_size 20M;

    location / {
        proxy_pass http://127.0.0.1:5000;
    }
}
