Attempting to Run Map Faces Results in Error With OpenCV

[ConnoisseurProtege]

Here's the error I'm getting -

Exception in Tkinter callback

I am not able to find create_source_target_popup in experimental branch

I am experiencing the same.

Replicate

1. Run the app
2. Put a Picture on the left and a Video on the right.
3. toggle Map faces
4. press Start

On Console output I get the following

Creating temp resources...

and then a second window pops-up, titled Source x Target Mapper, like below

Then no matter if I select another image (which btw I am not sure why I need to) the console remains as it is. If I click the Start button on the main window, I get prompted I should finish my business with the 2nd window. If I close the 2nd window and then click Start, then the app state reaches the same deadlock/bug as described above

Map faces works if you're planning to have multiple faces on the scene or if you want to target a specific face.
