How to run

Works on any OS

This main branch contains prerendered version that runs on a single computer. For real-time rendering using Unreal Engine 5.2 on a GPU, please visit real-time-render branch.

git clone https://github.com/ROC-HCI/SAPIEN.git
cd SAPIEN
pip install -r requirements.txt

• Download the folder: https://rochester.app.box.com/v/SAPIEN-public/folder/237414507812
• Place the folders static and speaking under: start_app/static/video/Metahumans
• Create keys.py from keys_template (rename to keys.py).py and add your own API keys for Microsoft Speech SDK, Azure OpenAI, and SERP (Not required; for enabling google search).
• Rename start_app/files/local_mode_dummy.json to start_app/files/local_mode.json.
• In "start_app/app.py", inside the "admin_required" function, put the email address you would be using to sign in.

cd start_app
python app.py

• Goto 0.0.0.0:80, and sign-in. Voila!

Other useful tips:

• Install ffmpeg and add it to Path.
  • [Windows] Add start_app/files/ffmpeg/bin to path.
• If you get errors to initiate sessions, after you sign in, go to "localhost/init_server" and click "Initialize Server". Run again.
