Face models not working (FFHQ, FacesHQ)

[HylisWilk]

Is anyone able to use these 2 models? I can't load them no matter what I try.
Latest error I'm getting is:

KeyError: 'Expected key target to instantiate.'

From ffhq.

If anyone is able to run these models please let me know how.

I had the same issue for a range of different models. It was driving me crazy. The issue is the difference between the official python pip package for taming-transformers and the github repo. It's solved by installing the github version.

pip install transformers
pip uninstall taming-transformers
pip install git+https://github.com/CompVis/taming-transformers

This should work for:
Ade20k
CelebAHQ
Cin
Coco
Drin
FacesHQ
FFHQ
Gumbel
Imagenet_1024
Imagenet_16384
SFlckr
Wikiart

Addendum:
If any of the models say they can't locate logs/something/last.ckpt, just edit the corresponding yaml file to alter this to the location of where you have your checkpoint file installed.

How do you change the model you want to use? I downloaded faceshq for instance with download_models.sh . I tried running generate.py with -m faceshq but it complains that the available models are models = ['RN50', 'RN101', 'RN50x4', 'RN50x16', 'ViT-B/32', 'ViT-B/16'].

@aliozcan That command isn't for the checkpoints files. If you would like to run the faceshq set for instance, you would use
python generate.py -p --vqgan_config checkpoints/faceshq.yaml --vqgan_checkpoint checkpoints/faceshq.ckpt
But this depends on a few things:

• Where you have the .yaml and .ckpt files
• What you named the .yaml and .ckpt files
• If the YAML file references a different location for the checkpoint file

Just like I stated in my addendum, if you receive an issue saying the .ckpt file can't be located, edit the yaml file in a text editor. Alter the existing path for the checkpoint/.ckpt file into where you have it installed.

@GucciFlipFlops1917 worked like a charm. Thanks.
