Tweak Story is an open-source project towards generating controllable Instagram captions, powered by PyTorch, Transformers and Streamlit. We apply attention-based condition LSTM network to generate engaging captions that can be tweaked by our users. With different attributes we offer, user can easily mix and match different combination of attributes for their own flavor. In current stage, we offer sentence length and emoji flag as available attributes.

Demo

You can find an online version of Tweak Story here.

App Structure

app has 4 major parts :

1. app.py - Main script for launching our Streamlit app
2. src - This folder contains all utility scripts for powering the app
3. ckpts - This folder contains model checkpoint, word map and configuration file for our model
4. demo - This folder contains example images you can try out in our app

Prerequisites (optional)

Download the following files and place them into ckpts folder

• model checkpoint
• word map file
• configuration file

Install and Run in Docker

Clone the repo and navigate to the repo:

git clone https://github.com/riven314/TweakStory.git
cd TweakStory/app

Build and run the docker image locally:

make run

Navigate to http://localhost:8501 for the app. (Streamlit runs on port 8501 by default)

Shutdown the server:

make stop 

Note : When you'll run the container for the first time it will download a resnet101 model. The Streamlit app is run in CPU.

Run Unit Test

cd TweakStory/app
pytest -s tests
