How to reindex facial recognition data in LR 6?

[dimkasmir]

I accidentally deleted all of the faces that Lightroom recognized in my photos upon the initial indexing. Is there anyway to reset the facial recognition index so that I can go through the process again?

Use Intelligent facial recognition in Lightroom Classic CC

Is #3 correct?

From the menu bar, choose Library > Find Faces Again.

My bad, I was viewing 7.2; it's correct in 7.3.

I cannot find "Find Faces Again" and I have the most recent version of Lightroom CC.  Any more specific directions as to where it is? When I follow these instructions I still do not see the option.

Recommended steps to upgrade the face records

• In Library module, select All Photographs in the Catalog panel.

• Select all photos in the Grid view or the Filmstrip. To select all photos, choose Edit > Select All or press Ctrl+A (Windows) or Command+A (macOS).
  

• From the menu bar, choose Library > Find Faces Again.

• In the Find Faces Again dialog, ensure that the following options are selected.

  • Skip Over Photos That Have Not Been Previously Indexed
  • Skip Over Photos With Manually Confirmed Faces
