class_docstr: Class for space of landmarks.
  
  The landmark space is a product manifold where all manifolds in the
  product are the same. The default metric is the product metric and
  is often referred to as the L2 metric.
  
  Parameters
  ----------
  ambient_manifold : Manifold
      Manifold to which landmarks belong.
  k_landmarks : int
      Number of landmarks.
code: def __init__(self, ambient_manifold, k_landmarks, equip=True):
      super().__init__(
          base_manifold=ambient_manifold,
          n_copies=k_landmarks,
          equip=equip,
      )
  
imports: from geomstats.geometry.nfold_manifold import NFoldManifold, NFoldMetric
label_desc: Use image node_id 1 to create a new Landmarks object from inherited base classes: NFoldManifold with example: obj = Landmarks(ambient_manifold, k_landmarks, equip)
