Issue trying new tensorflow version

I tested the new version with tensorflow, i get this error:

@kalwalt Sorry, I still couldn't replicate this error.

Maybe can you try running any tensorflowjs example first? https://www.tensorflow.org/js/demos

i will try again also with other devices and will test the examples you suggested :slightly_smiling_face:

[hiukim]

Thanks a lot! appreciated!

@kalwalt Just bumped the tfjs version from 2.x to 3.6. Not sure it helps, but worth a try.

Thank you for the news! I will test It.

@hiukim with my new Oppo A72 works fine all the examples! i will test also with my oldest device.

[hiukim]

@kalwalt good news! thanks for testing.
