- Pytorch 1.9.0+
Our annotation and model are based on BigGAN-512, please download the model from https://tfhub.dev/deepmind/biggan-512/2, store it in ./pretrain folder. Since the original model is trained using TensorFlow, you need to convert the model weights back to Pytorch, following the instructions here https://github.com/ajbrock/BigGAN-PyTorch/tree/master/TFHub. Notice the model is Licensed under Apache-2.0 issued by DeepMind.
We only release our annotations on sampled BigGAN images and images from ImageNet along with its latents used to get the sampled images. For their licenses, please refer to their websites. Notice our dataset release is under the Creative Commons BY-NC 4.0 license by NVIDIA Corporation. Please see License session for details.
- Download ImageNet from here.
- Download our annotations
annotations.zipand latent codeslatents.zipfrom gdrive. Unzip them into data folder under./data/. - Process images from ImageNet into our dataset format. Run the following script
python prepare_imagenet_images.py --imagenet_dir [path to imagenet dir] --dataset_dir ./data/
- Prepare images generated from BigGAN. Please download the pretrained weights following this session. And run
python prepare_biggan_images.py --biggan_ckpt ./pretrain/biggan-512.pth --dataset_dir ./data/
After the processing steps, you should have data folder structure like this

After the dataset preparation, we now can train BigDatasetGAN to synthesize dataset.
Run the following
python train.py --gan_ckpt ./pretrain/biggan-512.pth \
--dataset_dir ./data/ \
--save_dir ./logs/
You can monitor the training progress in tensorboard, as well as the training predictions in logs dir.
By default, the training runs 5k iteration with a batch size of 4, you can adjust it for the best capacity.
After the training is done, we can synthesize ImageNet with pixel-wise labels.
Run the following
python sample_dataset.py --ckpt [path to your pretrained BigDatasetGAN weights] \
--save_dir ./dataset_viz/ \
--class_idx 225, 200, [you can give it more with ImagetNet class idx] \
--samples_per_class 10
--z_var 0.9
As an example, here we sample class 225 and 200 with 10 samples each.
