I am seeing the seeing the same error. As far as I can tell this is because insightface is not detecting a face in the image.

steverhoades commented 5 months ago

OK, I think I figured it out. This occurs when a face is not detected in the image. There are a few things that factor into this.

  1. det_size is 640px by 640px
  2. img_resize is max 1280 pixels

If your face is taking up the majority of the pixels, i.e.> 640px, then it will fail to detect a face and show this error. Therefore, you will need to make sure your image is > 640 pixels and that the face is < 640 pixels of the entire image.

Thank you very much for the information you provided. I thought about your idea and solved this problem by adding the "Prepare imafe for insightface" node between the source face image and the "prepare image for clipvision" node. Problem solved.

@ZHO-ZHO-ZHO I think raising an error when face is not detected would be a good strategy here. Otherwise the end-user is left to interpret an arguably ambiguous error.
