tf.nn.l2_loss(t, name=None)L2 Loss.Computes half the L2 norm of a tensor without the sqrt:output = sum(t ** 2) / 2Args:t: A Tensor. Must be one of the following types: float32, float64, int64, int32, uint8, int16, int8, complex64, qint8, quint8, qint32. Typically 2-D, but may have any dimensions.name: A name for the operation (optional).Returns:A Tensor. Has the same type as t. 0-D.
