tensorflow: Class GpuDelegateFactory missing in Tensorflow Lite Java

It looks like the GpuDelegateFactory is missing in the latest version of tflite on Android.

When ipmorting with org.tensorflow.lite.gpu.GpuDelegateFactory, compilation fails with Unresolved reference: GpuDelegateFactory.

I have imported the following packages:

    implementation 'org.tensorflow:tensorflow-lite:2.10.0'
    implementation 'org.tensorflow:tensorflow-lite-api:2.10.0'
    implementation 'org.tensorflow:tensorflow-lite-gpu:2.10.0'
    implementation 'org.tensorflow:tensorflow-lite-gpu-delegate-plugin:0.4.2'
    implementation 'org.tensorflow:tensorflow-lite-support:0.4.2'

But none of these seem to contain GpuDelegateFactory.

Developers of library forgot to include a transitive dependency to tensorflow-lite-gpu-api from tensorflow-lite-gpu

@sachinprasadhs I’m guess, that the right solution is in adding transitive dependency from tensorflow-lite-gpu to tensorflow-lite-gpu-api. This is very unobvious, that the consumer of TensorFlow SDK must add an additional dependency manually. Fix will be available in the future version of TF SDK?

@mohantym importing DelegateFactory does not help. It really does seem like the class is just missing from the AAR, as @Erdemtsynduev points out.

Hi @mohantym . Looks like an issue in 2.10. I’m getting runtime exception with GpuDelegateFactory. Looks like it missing
