Use of Update() in vtk7

Support
1

read file for geometry

  reader = vtk.vtkXMLMultiBlockDataReader()
  reader.SetFileName(geometry_file)
  reader.Update()
  data = reader.GetOutput()
  data_iterator = data.NewIterator()
  img_data = data_iterator.GetCurrentDataObject() 
  img_data.Update()
  point_data = img_data.GetPointData()
  array_data = point_data.GetArray(0)
  np_array = vtk_to_numpy(array_data)
  img_shape = img_data.GetWholeExtent()
  np_shape = [img_shape[3] - img_shape[2] + 1, img_shape[1] - img_shape[0] + 1, 1]
  geometry_array = np_array.reshape(np_shape)
  if np.isnan(geometry_array).any():
    continue

ERROR:‘vtkmodules.vtkCommonDataModel.vtkImageData’ object has no attribute ‘Update’
Can you please tell me how to modify it?

You update a filter not the data. Just remove the Update() on the image data.
