Get started

1. install dependencies

pip install -r requirements.txt

2. initialize the fid stats

python init_fid_stats.py

Demo

The following command calculates the Inception score & FID of FSVAE trained on CelebA. After that, it outputs demo_input.png, demo_recons.png, and demo_sample.png.

python demo.py

Training Fully Spiking VAE

python main_fsvae exp_name -config NetworkConfigs/dataset_name.yaml

Training settings are defined in NetworkConfigs/*.yaml.

args:

• name: [required] experiment name
• config: [required] config file path
• checkpoint: checkpoint path (if use pretrained model)
• device: device id of gpu, default 0

You can watch the logs with below command and access http://localhost:8009/

tensorboard --logdir checkpoint --bind_all --port 8009

Training ANN VAE

As a comparison method, we prepared vanilla VAEs of the same network architecture built with ANN, and trained on the same settings.

python main_ann_vae exp_name -dataset dataset_name

args:

• name: [required] experiment name
• dataset:[required] dataset name [mnist, fashion, celeba, cifar10]
• batch_size: default 250
• latent_dim: default 128
• checkpoint: checkpoint path (if use pretrained model)
• device: device id of gpu, default 0
