Can only be run on GPU with the TensorFlow back end. Corresponds to the CuDNNGRU Keras layer .
- Type: Keras Deep Learning NetworkKeras NetworkThe Keras deep learning network to which to add an CuDNN GRU layer.
- Type: PortObjectKeras NetworkAn optional Keras deep learning network which provides the initial hidden state for this CuDNN GRU layer. The hidden state must have shape [units], where units must correspond to the number of units this layer uses.
