class LocationNetworkNew(nn.Module):
    """The location network.

    Uses the internal state `h_t` of the core network to
    produce the location coordinates `l_t` for the next
    time step.

    Concretely, feeds the hidden state `h_t` through a fc
    layer followed by a tanh to clamp the output beween
    [-1, 1]. This produces a 2D vector of means used to
    parametrize a two-component Gaussian with a fixed
    variance from which the location coordinates `l_t`
    for the next time step are sampled.

    Hence, the location `l_t` is chosen stochastically
    from a distribution conditioned on an affine
    transformation of the hidden state vector `h_t`.

    Args:
        input_size: input size of the fc layer.
        output_size: output size of the fc layer.
        std: standard deviation of the normal distribution.
        h_t: the hidden state vector of the core network for
            the current time step `t`.

    Returns:
        mu: a 2D vector of shape (B, 2).
        l_t: a 2D vector of shape (B, 2).
