GPU Delegation error in Andoid (java.lang.IllegalArgumentException: Internal error: Error applying delegate:)

i have completed a keral_nlp,english to spanish translation task check this below colab notebook https://colab.research.google.com/drive/1qTDpDp1N6gyejkzmuCfrTtGVX1EJsnve#scrollTo=ctUYMsASP46V
in this i have created a "BeamSampler" tflite model it was working fine ,but in android side for better performance(faster inference) acheiving ,while applying GPU delegate, getting this error "java.lang.IllegalArgumentException: Internal error: Error applying delegate:"

please help me how to overcome this issue
tflite model contains these ops:(10,
array(['CAST', 'CONCATENATION', 'EXPAND_DIMS', 'GATHER', 'RESHAPE',
'SHAPE', 'STRIDED_SLICE', 'TILE', 'TOPK_V2', 'WHILE'], dtype='<U13'))

i already gone through this documentation https://www.tensorflow.org/lite/performance/gpu

i am using this code to enabling the GPU Delegate(Android)
CompatibilityList compatList = new CompatibilityList();if(compatList.isDelegateSupportedOnThisDevice()){ // if the device has a supported GPU, add the GPU delegate GpuDelegateFactory.Options options1 = new GpuDelegateFactory.Options().setQuantizedModelsAllowed(true); GpuDelegate gpuDelegate = new GpuDelegate(options1); opt.addDelegate(gpuDelegate);} else { // if the GPU is not supported, run on 4 threads options.setNumThreads(4);}

i am using this TFVersion org.tensorflow/tensorflow-lite-api) » 2.13.0

Start with the Android GPU delegate setup using CompatibilityList, GpuDelegateFactory, and GpuDelegate, then compare the model's listed ops with the TensorFlow Lite GPU delegate documentation and the linked Colab notebook. Done means determining which operation or model constraint causes delegate application to fail, or documenting that this model cannot use the GPU delegate.
