A detailed tutorial covering the code in this repository: Turning design mockups into code with deep learning.

The neural network is built in three iterations. Starting with a Hello World version, followed by the main neural network layers, and ending by training it to generalize.

The models are based on Tony Beltramelli's pix2code, and inspired by Airbnb's sketching interfaces, and Harvard's im2markup.

Note: only the Bootstrap version can generalize on new design mock-ups. It uses 16 domain-specific tokens which are translated into HTML/CSS. This version can be trained on a few GPUs. The raw HTML version has potential to generalize, but is still unproven and requires a few hundred GPUs to train.

A quick overview of the process:

1) Give a design image to the trained neural network

Insert image

2) The neural network converts the image into HTML markup

3) Rendered output

Installation

FloydHub

Run on FloydHub

Click this button to open a Workspace on FloydHub where you will find the same environment and dataset used for the Bootstrap version. You can also find the trained models for testing.

pip install floyd-cli
floyd login
git clone https://github.com/emilwallner/Screenshot-to-code-in-Keras
cd Screenshot-to-code-in-Keras/floydhub 
floyd init projectname
floyd run --gpu --env tensorflow-1.4 --data emilwallner/datasets/imagetocode/2:data --data emilwallner/datasets/html_models/1:weights --mode jupyter

Local

pip install keras tensorflow pillow h5py jupyter
git clone https://github.com/emilwallner/Screenshot-to-code-in-Keras
cd Screenshot-to-code-in-Keras/local
jupyter notebook

Go do the desired notebook, files that end with '.ipynb'. To run the model, go to the menu then click on Cell > Run all

The final version, the Bootstrap version, is prepared with a small set to test run the model. If you want to try it with all the data, you need to download the data here: https://www.floydhub.com/emilwallner/datasets/imagetocode, and specify the correct dir_name.
