CRITICAL Error caught! Exiting...
ERROR Caught exception in thread: '_training_0'
ERROR You have selected the mask type 'bisenet-fp_face' but at least one face does not contain the selected mask.
ERROR The face that failed was: 'F:\work\1\1_000853_0.png'
ERROR The masks that exist for this face are: ['components', 'extended', 'vgg-clear']
I don't know what I can really add to the error message. You do not have the bisenet-fp mask in your training set.
Either generate the missing bisenet-fp mask for your face sets with the Mask Tool, or go into the Model configuration settings and change the mask to one of components, extended or vgg-clear.
