With the touchscreen connected, and after setting up the Pi upon bootup for the first time, including:

• Hostname
• User and password
• Wireless LAN SSID and password
• Locale settings

Enable SSH, I2C and Remote GPIO, using the touchscreen:

• Pi icon → Preferences → Raspberry Pi Configuration → Interfaces → SSH (enable)
• Pi icon → Preferences → Raspberry Pi Configuration → Interfaces → I2C (enable)
• Pi icon → Preferences → Raspberry Pi Configuration → Interfaces → Remote GPIO (enable)

Or using the Terminal and a keyboard:

sudo raspi-config

• Interface Options -> SSH -> Yes
• Interface Options -> I2C -> Yes
• Interface Options -> Remote GPIO -> Yes

Then install picamera2 and opencv with apt install:

sudo apt update
sudo apt install -y python3-picamera2
sudo apt install -y python3-opencv
sudo apt install -y opencv-data
sudo apt install -y portaudio19-dev

Make (and enter) a project directory:

cd
mkdir Pi5Robot
cd Pi5Robot

Create a virtual environment:

python3 -m venv venv

Activate it:

source venv/bin/activate

And install the rest of the dependencies with pip:

pip install adafruit-circuitpython-pca9685
pip install adafruit-circuitpython-motor
pip install deepface
pip install tf-keras
pip install facenet-pytorch
pip install rpi-lgpio
pip install mediapipe
pip install pyaudio
pip install websockets

Make the apt-installed libraries accessible from within the virtual environment:

echo "/usr/lib/python3/dist-packages" > $(python -c "import site; print(site.getsitepackages()[0])")/system_packages.pth

Downgrade numpy because 2.0.0 seems incompatible:

pip install "numpy<2.0.0"

And this should now work:

python -c "from picamera2 import Picamera2; print(Picamera2)"
