models/hand_landmarker.task doesn't exist

[fractalbob]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

Yes

OS Platform and Distribution

Ubuntu 24.04.1 LTS

Python Version

3.9.7

MediaPipe Model Maker version

MediaPipe Tasks Vision library (which currently resolves to version 0.20230731).

Task name (e.g. Image classification, Gesture recognition etc.)

Hand Landmarker (Hand Tracking)

Describe the actual behavior

Calling setModelAssetPath("models/hand_landmarker.task") returns file not found

Describe the expected behaviour

models/hand_landmarker.task should exist

Standalone code/steps you may have used to try to get what you need

private void setupHandTracking() {         HandLandmarker.HandLandmarkerOptions options = HandLandmarker.HandLandmarkerOptions.builder()                 .setBaseOptions(BaseOptions.builder()                         .setModelAssetPath("models/hand_landmarker.task")  // ✅ Correct format with a subdirectory                         .build())                 .setRunningMode(RunningMode.LIVE_STREAM)                 .setResultListener((HandLandmarkerResult result, MPImage image) -> {                     // ✅ This callback is required when using LIVE_STREAM mode                     if (result != null && !result.landmarks().isEmpty()) {                         System.out.println("Detected hand landmarks: " + result.landmarks().get(0));                     }                 })                 .build();          // Debugging: Verify if the model file is available before initializing HandLandmarker         File modelFile = new File(getFilesDir(), "models/hand_landmarker.task");          if (!modelFile.exists()) {             Log.e("HandLandmarker", "❌ Model file NOT FOUND at: " + modelFile.getAbsolutePath());         } else {             Log.d("HandLandmarker", "✅ Model file FOUND at: " + modelFile.getAbsolutePath());         }          handLandmarker = HandLandmarker.createFromOptions(this, options);     }

Hi @fractalbob,

Could you please provide more details, including a complete, standalone code that can help us reproduce the issue on our end?

Thank you!!

Here's a reproducible test case: https://drive.google.com/file/d/1MGRkQ0bWYMVKe25Dp5hug9oW9ZdjUR0A/view?usp=sharing. Unzip the file and open the resulting folder with Android Studio, then run the app. It should fail in MainActivity.java at line 207 with a SEGV fault because the file models/hand_landmarker.task doesn't exist.
