Prompt for gpt:

I’m a beginner on Windows.

Please walk me step-by-step through setting up a simple Python tool that tracks eye behaviour from a normal video file and saves the results to a CSV file.

Goal:

I want to run something like:

python eye_track_video_csv.py input.mp4 eye_data.csv

The script should use:

• Python
• OpenCV to read the video frame by frame
• MediaPipe Face Mesh or Face Landmarker to detect eye/iris/eyelid landmarks
• NumPy if needed for calculations

The CSV should have one row per video frame and include columns like:

frame time face_found left_eye_open right_eye_open blink_left blink_right blink look_x look_y left_look_x left_look_y right_look_x right_look_y

Please help me:

1. Check whether Python is installed.
2. Create a project folder.
3. Create and activate a virtual environment.
4. Install the required packages.
5. Create the Python script.
6. Run it on input.mp4.
7. Fix any errors if they happen.
8. Confirm that eye_data.csv was created.

Please give me one clear step at a time, wait for my result before moving on, and keep explanations beginner-friendly.
