def __init__(self,
        Create a QRNN model.


            input_dim(int): The dimension of the measurement space, i.e. the number
                            of elements in a single measurement vector y

            quantiles(np.array): 1D-array containing the quantiles  to estimate of
                                 the posterior distribution. Given as fractions
                                 within the range [0, 1].

            depth(int): The number of hidden layers  in the neural network to
                        use for the regression. Default is 3, i.e. three hidden
                        plus input and output layer.

            width(int): The number of neurons in each hidden layer.

            activation(str): The name of the activation functions to use. Default
                             is "relu", for rectified linear unit. See 
                             `this <>`_ link for
                             available functions.

            **kwargs: Additional keyword arguments are passed to the constructor
                      call `keras.layers.Dense` of the hidden layers, which can
                      for example be used to add regularization. For more info consult
