hey i want a command to run jjk hand sign detector...

Use this from the project folder:

bash
python main.py

or, if the file is named differently:

bash
python app.py

But since you’re on Python 3.14.1, most JJK hand-sign detector projects that use MediaPipe / OpenCV / TensorFlow may not install or run cleanly yet. MediaPipe/OpenCV-based hand tracking projects are common for JJK hand-sign detectors, and the Roboflow Jujutsu Kaisen model is an object-detection API/model rather than a simple local script. (Roboflow)

Best fix: run it with Python 3.11 or 3.12 in a virtual environment:

bash
py -3.11 -m venv .venv
.venv\Scripts\activate
pip install -r requirements.txt
python main.py

On Mac/Linux:

bash
python3.11 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python main.py

If there is no main.py, list the files:

bash
dir

or Mac/Linux:

bash
ls

Then run the detector file, for example:

bash
python hand_detector.py

For Python 3.14.1, expect install errors with packages like mediapipe, opencv-python, or tensorflow; OpenCV and TensorFlow compatibility with Python 3.14 has been a known issue area. (stackoverflow.com)

For Python 3.14.1, try this command first:

bash
python -m pip install --upgrade pip setuptools wheel
python -m pip install opencv-python numpy
python main.py

If you’re on Windows and python is not your 3.14.1 install, use:

bash
py -3.14 -m pip install --upgrade pip setuptools wheel
py -3.14 -m pip install opencv-python numpy
py -3.14 main.py

If the detector uses MediaPipe, the command would usually be:

bash
py -3.14 -m pip install mediapipe opencv-python numpy
py -3.14 main.py

But this may fail because MediaPipe has had missing wheel/support issues for newer Python versions, including 3.13+, and Python 3.14 support may not be available for your setup. (GitHub)

If it uses TensorFlow, try:

bash
py -3.14 -m pip install tensorflow opencv-python numpy
py -3.14 main.py

TensorFlow 3.14 support has been actively tracked as a compatibility issue, so this may also fail depending on your platform and package version. (GitHub)

So the real run command is probably:

bash
py -3.14 main.py

If your file is not main.py, run this to see the Python files:

bash
dir *.py

Then run the correct one, for example:

bash
py -3.14 hand_detector.py
