title: AttributeError: module 'open3d' has no attribute 'PointCloud'
body: <p>I'm trying to an example code in my vsc editor. However, I got the AttributeError: module 'open3d' has no attribute 'PointCloud'error. I looked how to fix this problem but none of those are worked. Looking for any help. I'm using Win10 and Python 3.8. Thanks in advance</p>
  <pre><code>import open3d as o3d
  import numpy as np
  
  pc_array = np.array([[1, 2, 3], [3, 4, 5]], dtype=np.float32)
  print(pc_array)
  
  pc = o3d.PointCloud()
  pc.points = o3d.Vector3dVector(pc_array)
  print(pc)
  </code></pre>
