SketchCode

Generating HTML Code from a hand-drawn wireframe

SketchCode is a deep learning model that takes hand-drawn web mockups and converts them into working HTML code. It uses an image captioning architecture to generate its HTML markup from hand-drawn website wireframes.

For more information, check out this post: Automating front-end development with deep learning

This project builds on the synthetically generated dataset and model architecture from pix2code by Tony Beltramelli and the Design Mockups project from Emil Wallner.

Note: This project is meant as a proof-of-concept; the model isn't (yet) built to generalize to the variability of sketches seen in actual wireframes, and thus its performance relies on wireframes resembling the core dataset.

Setup

Prerequisites

• Python 3 (not compatible with python 2)
• pip

Install dependencies

pip install -r requirements.txt

Example Usage

Download the data and pretrained weights:

# Getting the data, 1,700 images, 342mb
git clone https://github.com/ashnkumar/sketch-code.git
cd sketch-code
cd scripts

# Get the data and pretrained weights
sh get_data.sh
sh get_pretrained_model.sh

Converting an example drawn image into HTML code, using pretrained weights:

cd src

python convert_single_image.py --png_path ../examples/drawn_example1.png \
      --output_folder ./generated_html \
      --model_json_file ../bin/model_json.json \
      --model_weights_file ../bin/weights.h5

General Usage

Converting a single image into HTML code, using weights:

cd src

python convert_single_image.py --png_path {path/to/img.png} \
      --output_folder {folder/to/output/html} \
      --model_json_file {path/to/model/json_file.json} \
      --model_weights_file {path/to/model/weights.h5}

Converting a batch of images in a folder to HTML:

cd src

python convert_batch_of_images.py --pngs_path {path/to/folder/with/pngs} \
      --output_folder {folder/to/output/html} \
      --model_json_file {path/to/model/json_file.json} \
      --model_weights_file {path/to/model/weights.h5}

Train the model:

cd src

# training from scratch
# <augment_training_data> adds Keras ImageDataGenerator augmentation for training images
python train.py --data_input_path {path/to/folder/with/pngs/guis} \
      --validation_split 0.2 \
      --epochs 10 \
      --model_output_path {path/to/output/model}
      --augment_training_data 1

# training starting with pretrained model
python train.py --data_input_path {path/to/folder/with/pngs/guis} \
      --validation_split 0.2 \
      --epochs 10 \
      --model_output_path {path/to/output/model} \
      --model_json_file ../bin/model_json.json \
      --model_weights_file ../bin/pretrained_weights.h5 \
      --augment_training_data 1

Evalute the generated prediction using the BLEU score

cd src

# evaluate single GUI prediction
python evaluate_single_gui.py --original_gui_filepath  {path/to/original/gui/file} \
      --predicted_gui_filepath {path/to/predicted/gui/file}

# training starting with pretrained model
python evaluate_batch_guis.py --original_guis_filepath  {path/to/folder/with/original/guis} \
      --predicted_guis_filepath {path/to/folder/with/predicted/guis}
