Error is,
ValueError: Graph disconnected: cannot obtain value for tensor KerasTensor(type_spec=TensorSpec(shape=(None, 156), dtype=tf.float32, name=‘input_9’), name=‘input_9’, description=“created by layer ‘input_9’”) at layer “sequential_3”. The following previous layers were accessed without issue: [‘sequential_5’]
You can visualize the graph with tf.keras.utils.plot_model(model, show_shapes=True, show_dtype=True). It could help to find disconnected parts of the graph or errors in the model architecture.
In order to reproduce the issue reported, could you please provide the standalone code.Thank you.
