I am getting the following Error while executing KNIME nework Learner, please help
Execute failed: An error occurred while creating the Keras network from its layer specifications. Details: Tensors are unhashable (this tensor: KerasTensor(type_spec=TensorSpec(shape=(1, 28, 28, 1), dtype=tf.float32, name=‘input_1’), name=‘input_1’, description=“created by layer ‘input_1’”)). Instead, use tensor.ref() as the key.

@mbejawar welcome to the KNIME forum. You will have to install a specific combination of versions for deep learning packages.
