Setup instructions

• Install dependencies

pip install PyQt5 numpy opencv-python openai tenacity pygame
pip install tensorflow==2.15.0

(The FER classifier was trained with an older version of Keras, which is why we force tensorflow version 2.15.0. This is kludgy and we should find a more elegant way, but it doesn’t matter much because we’re not training the FER classifier, just using it black box.)

• Test out the emotion visualizer!

python3 tunnel.py

It should open a GUI with 2 tabs, one shows the camera feed with boxes around any faces detected, the other shows a color-coded “tunnel” of the real-time emotions detected.

-Troubleshooting: if the camera doesn’t open, try listing available cameras:

python3 camera-check.py

tunnel.py opens camera ‘0’ by default, which is usually the laptop camera on a mac, but to force a different camera, you can use the camera_id flag:

python3 tunnel.py --camera_id 1

• Make faces and experiment with the FER classifier and visualizer! It works well in most situations but not if backlit.

• Test out the video chat! You’ll need an OpenAI API key.

python3 videochat.py

It should open a GUI with 3 tabs: chat, FER, and transcript. Use the bottom of the chat tab to chat with GPT-4, press enter to send.

• You’ll notice that Emili chats with you unprompted sometimes. That’s because every so often she sees a snapshot from the camera. Also, when your emotions change, she sees a summary of the recent emotion data. You can see exactly what gets sent in the “transcript” tab.

• Have fun!
