I am using mediapipe/hands in a web app.
And now finding a way to use this on my local machine offline mode.
Is there any solution?

Hi @georgelxl6,

Yes, you can run the npm package offline. However, it seems you are using the legacy @mediapipe/hands package (please correct me if I am wrong). This solution has been upgraded and is now part of the Task Vision package https://www.npmjs.com/package/@mediapipe/tasks-vision. Here's an example implementation for the updated Hand Landmarker:

const vision = await FilesetResolver.forVisionTasks(
    "https://cdn.jsdelivr.net/npm/@mediapipe/tasks-vision/wasm"
);
const handLandmarker = await HandLandmarker.createFromModelPath(vision,
    "https://storage.googleapis.com/mediapipe-models/hand_landmarker/hand_landmarker/float16/1/hand_landmarker.task"
);
const image = document.getElementById("image") as HTMLImageElement;
const landmarks = handLandmarker.detect(image);

You can find the Hand Landmarker overview here and the web implementation guide here.(https://ai.google.dev/edge/mediapipe/solutions/vision/hand_landmarker) and Implenetation for Web you can find here.

Please note that support for the old package @mediapipe/hands has been discontinued, as mentioned here. Let us know if you encounter any issues!

Thank you!!

Hi @kuaashish,

Thank you for your response.
Yes, it’s similar to what I’m using now.
However, I’m planning to use it locally.
The link below will not work offline:

Thank you
