Error: Key generator/encoder_8/conv/filter not found in checkpoint

Hey, I just finished training for ~2 days and now tried to continue with your instructions.
Since that step isn't described: I guessed I had to copy the face2face-model folder over to the root of your projects folder and then ran:
python reduce_model.py --model-input face2face-model --model-output face2face-reduced-model
Unfortunately that led to a big error message:

During handling of the above exception, another exception occurred:

I have to admit that I never worked with tensorflow and used the version 1.4.1. I tried downgrading to 1.2.1 but that led to another error. Should I retrain with the older version of tensorflow or am I missing something else?

The problem here is that pix2pix has been updated after trained this demo. So you can reset back to April version that everything will be work. Hope this can help you.

Thanks, that solved it :)
