class_docstr: Shared noise table used by learner and actor.
  
  Learner and actor will create a same noise table by passing the same seed.
  With the same noise table, learner and actor can communicate the noises by
  index of noise table instead of numpy array of noises.
code: def get(self, i, dim):
      return self.noise[i : i + dim]
  
imports: import numpy
label_desc: Use image node_id 3 for calling the SharedNoiseTable obj's underlying member method code with example usage: obj.get(i, dim) and returns: self
