Training

To reproduce paper DatasetGAN: Efficient Labeled Data Factory with Minimal Human Effort:

cd datasetGAN

1. Run Step1: Interpreter training.
2. Run Step2: Sampling to generate massive annotation-image dataset.
3. Run Step3: Train Downstream Task.

1. Interpreter Training

python train_interpreter.py --exp experiments/<exp_name>.json 

Note: Training time for 16 images is around one hour. 160G RAM is required to run 16 images training. One can cache the data returned from prepare_data function to disk but it will increase trianing time due to I/O burden.

Example of annotation schema for Face class. Please refer to paper for other classes.

Download Checkpoints

2. Run GAN Sampling

python train_interpreter.py \
--generate_data True --exp experiments/<exp_name>.json  \
--resume [path-to-trained-interpreter in step3] \
--num_sample [num-samples]

To run sampling processes in parallel

sh datasetGAN/script/generate_face_dataset.sh

Example of sampling images and annotation:

3. Train Downstream Task

python train_deeplab.py \
--data_path [path-to-generated-dataset in step4] \
--exp experiments/<exp_name>.json

Inference

python test_deeplab_cross_validation.py --exp experiments/face_34.json\
--resume [path-to-downstream task checkpoint] --cross_validate True

June 21 Update:

For training interpreter, we change the upsampling method from nearnest upsampling to bilinar upsampling in line and update results in Table 1. The table reports mIOU.

Sep 12 Update:

Thanks for @greatwallet. According to issue, we fixed a uncertainty score calculation bug. The Ours-Fix row shows the results.

Create your own model

To create your own model, please follow the following steps:

1. Train your own stylegan model using official Stylegan code and convert the tensorflow checkpoint to pytorch. Specific stylegan path in

   datasetGAN/experiments/customized.json

2. Run python datasetGAN/make_training_data.py --exp datasetGAN/experiments/customized.json --sv_path ./new_data .

   This function will generate sample images and dump two numpy files in sv_path.

   a. avg_latent_stylegan1.npy (Dim: 18 *512) is used for truncation. It's average of w latent space. We sample 8000 from z space and calculate average of w.

   b. latent_stylegan1.npy (Dim: number_data *512) is cache z latent codes to retrive corresponding training images.

3. Annotate image as you like, follow the file format in google drive and put annotation in the folder of ./datasetGAN/dataset_release.
