Hi! Thanks for your excellent work

I am trying to train an encoder on FFHQ-256(simply downsample by 4, no other difference). I followed your instructions, using pretrained model from rosinality's pytorch (he trained a ffhq-256 generator, fid about 4.5).

The training command is:

python scripts/train.py \
    --dataset_type ffhq256_encode \
    --exp_dir ffhq256_runs \
    --start_from_latent_avg \
    --use_w_pool \
    --w_discriminator_lambda 0.1 \
    --progressive_start 20000 \
    --id_lambda 0.5 \
    --val_interval 10000 \
    --max_steps 200000 \
    --stylegan_size 256 \
    --stylegan_weights pretrained/ffhq256.pt \
    --workers 8 \
    --batch_size 8 \
    --test_batch_size 4 \
    --test_workers 4

And the timestamp log is

I am wondering whether the loss log is reasonable and do you have any advice on training a ffhq-256 encoder

some example inversions:

here are the logs/images/test/face at 200k iterations

Thank you very much!

Hi，

Hi! Thanks for your excellent work

I am trying to train an encoder on FFHQ-256(simply downsample by 4, no other difference). I followed your instructions, using pretrained model from rosinality's pytorch (he trained a ffhq-256 generator, fid about 4.5).

The training command is:

python scripts/train.py \
    --dataset_type ffhq256_encode \
    --exp_dir ffhq256_runs \
    --start_from_latent_avg \
    --use_w_pool \
    --w_discriminator_lambda 0.1 \
    --progressive_start 20000 \
    --id_lambda 0.5 \
    --val_interval 10000 \
    --max_steps 200000 \
    --stylegan_size 256 \
    --stylegan_weights pretrained/ffhq256.pt \
    --workers 8 \
    --batch_size 8 \
    --test_batch_size 4 \
    --test_workers 4

And the timestamp log is

I am wondering whether the loss log is reasonable and do you have any advice on training a ffhq-256 encoder

here are the logs/images/test/face at 200k iterations image image

Thank you very much!

Hi, did you solve your problem？ I encountered a same problem with you!
Thank you very much!
