      The input to the LSTM cell, shape (batch_size, num_inputs).
    cs_prev: A `Tensor`. Must have the same type as `x`.
      The previous cell state.
    h_prev: A `Tensor`. Must have the same type as `x`. The previous h state.
    w: A `Tensor`. Must have the same type as `x`. The weight matrix.
    wci: A `Tensor`. Must have the same type as `x`.
      The weight matrix for input gate peephole connection.
    wcf: A `Tensor`. Must have the same type as `x`.
      The weight matrix for forget gate peephole connection.
    wco: A `Tensor`. Must have the same type as `x`.
      The weight matrix for output gate peephole connection.
    b: A `Tensor`. Must have the same type as `x`. The bias vector.
    i: A `Tensor`. Must have the same type as `x`. The input gate.
    cs: A `Tensor`. Must have the same type as `x`.
      The cell state before the tanh.
    f: A `Tensor`. Must have the same type as `x`. The forget gate.
    o: A `Tensor`. Must have the same type as `x`. The output gate.
    ci: A `Tensor`. Must have the same type as `x`. The cell input.
    co: A `Tensor`. Must have the same type as `x`. The cell after the tanh.
    cs_grad: A `Tensor`. Must have the same type as `x`.
      The current gradient of cs.
    h_grad: A `Tensor`. Must have the same type as `x`.
      The gradient of h vector.
    use_peephole: A `bool`. Whether the cell uses peephole connections.
    name: A name for the operation (optional).

  Returns:
    A tuple of `Tensor` objects (cs_prev_grad, dicfo, wci_grad, wcf_grad, wco_grad).

    cs_prev_grad: A `Tensor`. Has the same type as `x`. The gradient of cs to be back-propped.
    dicfo: A `Tensor`. Has the same type as `x`. The derivative wrt to [i, cs, f, o].
    wci_grad: A `Tensor`. Has the same type as `x`. The gradient for wci to be back-propped.
    wcf_grad: A `Tensor`. Has the same type as `x`. The gradient for wcf to be back-propped.
    wco_grad: A `Tensor`. Has the same type as `x`. The gradient for wco to be back-propped.
