getting issue in this line of code -> attn_out, attn_states = attn_layer([encoder_outputs, decoder_outputs]) #1
Description
Exception encountered when calling layer "tf.keras.backend.rnn" (type TFOpLambda).
You are passing KerasTensor(type_spec=TensorSpec(shape=(None, 35), dtype=tf.float32, name=None), name='tf.nn.softmax_1/Softmax:0', description="created by layer 'tf.nn.softmax_1'"), an intermediate Keras symbolic input/output, to a TF API that does not allow registering custom dispatchers, such as tf.cond, tf.function, gradient tapes, or tf.map_fn. Keras Functional model construction only supports TF API calls that do support dispatching, such as tf.math.add or tf.reshape. Other APIs cannot be called directly on symbolic Kerasinputs/outputs. You can work around this limitation by putting the operation in a custom Keras layer call and calling that layer on this symbolic input/output.
