[RN] Pose Detection not working on android.

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): MacOS Monterey 12.0.1
• Mobile device (e.g. iPhone 8, Pixel 2, Samsung Galaxy) if the issue happens on mobile device: Samsung Galaxy S10 5G
• TensorFlow.js installed from (npm or script link): npm
• TensorFlow.js version (use command below): ^0.8.0
• Browser version: Chrome 96.0

• Expo version : 43.0.0

Describe the current behavior Pose estimation not working properly only on Android. (keypoints are detected, but very low score)

There was no error during preparation (load model, handleImageTensorReady). Also, camera preview works properly.

Describe the expected behavior Pose estimation should work same as IOS.

Standalone code to reproduce the issue Provide a reproducible test case that is the bare minimum necessary to generate the problem. If possible, please share a link to Colab/CodePen/any notebook.

Other info / logs Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached.

@rthadur I tested the working example on both OS, but neither worked. (Galaxy S10 5G, iPhone 11 Pro)

Result IOS : app crashed after warning: initialization of backend rn-webgl failed Android : only black screen displayed.(both front/back camera) frame rate was about 4~5fps.

Test Process

1. clone repo
2. yarn && yarn start
3. Scan QR code and launch app with Expo Go

@rthadur @jinjingforever Thank you for the update. I’ve tested the example on Samsung Galaxy S10, but the example still not working properly.

Expected behavior keypoints should be displayed just like the image on the README.md

Actual behavior App does not crashed, but the keypoints(green circles) not displayed properly. (only 1-2 circles shown randomly)

Test Process

1. clone repo
2. yarn => Failed with error An unexpected error occurred: "https://registry.yarnpkg.com/colors/-/colors-1.4.2.tgz: Request failed \"404 Not Found\"".
3. rm yarn.lock
4. yarn && yarn start
5. set camera to front and adjust position to show my face and shoulder. (just like image on README.md)
