blazeface No face detected in FIRST source image

[reefor]

Hi, I hope this is the right place to post this question.

I'm trying to use Blazeface in a Liveportrait workflow in the Liveportrait LoadFaceAlignment Cropper Node. I had it working a few weeks ago but had to uninstall and reinstall. Now Blazeface & Blazeface Back Camera both give the error message: blazeface No face detected in FIRST source image

I was able to get SFD to work, so my first question is if SFD is just as good. If it is, please let me know and ignore the rest.

I seem to remember that there was a setting for "confidence" that would fix this problem, but I looked through every node 3 times and can't find it.

I also read somewhere that blazeface uses 6 keypoints. 2 eyes, 2 ears, nose, & mouth. The subject has her ears covered by long hair. Could this cause the problem?

Those are the causes I could think of. If someone can give me some ideas I'd really appreciate it.
