Titan Image Generator v2 Outpainting Example

Simple Streamlit application that uses the Amazon Bedrock API to call the Amazon Titan Image Generator v2 model and replaces an image's background using outpainting.

Foundation Model Access

Ensure you have access to the Amazon Titan Image Generator G1 v2 model in the "Model access" tab of the Amazon Bedrock Web Console.

Prepare Local Environment

Create Python virtual environment locally and install required packages (1x only). Script assumes you already have a recent version of Python 3 installed and use a python3 alias.

Mac

# I am running Python 3.12 or later
python3 --version

python3 -m venv .venv
source .venv/bin/activate

pip install pip --upgrade
pip install -r requirements.txt --upgrade

Windows

REM I am running Python 3.12 or later
python --version 

python -m venv .venv
.venv\Scripts\activate

python -m pip install pip --upgrade
python -m pip install -r requirements.txt --upgrade

Authenticate to AWS

Provide your AWS credential on the commandline or authenticate in your normal way before starting the application.

Mac

export AWS_ACCESS_KEY_ID="<YOUR_AWS_ACCESS_KEY_ID>"
export AWS_SECRET_ACCESS_KEY="<YOUR_AWS_SECRET_ACCESS_KEY>"
export AWS_SESSION_TOKEN="<YOUR_AWS_SESSION_TOKEN>"

Windows

SET AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY_ID
SET AWS_SECRET_ACCESS_KEY=YOUR_AWS_SECRET_ACCESS_KEY
SET AWS_SESSION_TOKEN=YOUR_AWS_SESSION_TOKEN

Run Streamlit Application

Start the Streamlit application. The application should start locally on http://localhost:8501 and open in your web browser automatically. View the terminal output for more logging information.

streamlit run app.py --server.runOnSave true

You can pass custom arguments to Streamlit when starting the application. For example:

Mac

streamlit run app.py \
    --server.runOnSave true \
    --theme.base "dark" \
    --theme.backgroundColor "#26273B" \
    --theme.primaryColor "#ACADC1" \
    --theme.secondaryBackgroundColor "#454560" \
    --theme.font "sans serif"\
    --ui.hideTopBar "true" \
    --client.toolbarMode "minimal"

Windows

streamlit run app.py ^
    --server.runOnSave true ^
    --theme.base "dark" ^
    --theme.backgroundColor "#26273B" ^
    --theme.primaryColor "#ACADC1" ^
