Setup Local Stylegan

1. Refer to the Github Page

For major installation process refer to the stylegan3 GitHub Page.

This is an in-depth YouTube tutorial on how to install stylegan3 locally

Inference

For generating single images and videos, you may follow these steps.

activating conda environment

this needs to be done before every session if you want to use stylegan

conda init bash

source ~/.bashrc

conda activate stylegan3

alternatively if you are not able to activate stylegan3 through the terminal on our workstations, you can use the anaconda Navigator and start the terminal with the environment activated:

inference images

python gen_images.py --outdir=out --trunc=1 --seeds=2 --network=https://api.ngc.nvidia.com/v2/models/nvidia/research/stylegan3/versions/1/files/stylegan3-r-afhqv2-512x512.pkl

inference video

python gen_video.py --output=out/wikiart.mp4 --trunc=1 --seeds=0-31 --network=pretrained/wikiart.pkl

Training

For training your own datasets, you can follow these steps.

For your own dataset make sure that your training data has the correct resolution. You may use either 1024x1024, 512x512 or 256x256 resolution. The chosen resolution has to match with the pre-existing dataset that you want to train on.
You may start a dataset from scratch, just be aware that generally training your collected images on a pre-existing dataset will usually give better results (and faster ones too).

Dowload Training data

If not done before, set up a new directory for the training data

mkdir trainingdata

If you want to download your trainingdata from a sciebo folder, you may use this code. Instead of the given link you may use your own one.

wget --no-check-certificate --content-disposition https://th-koeln.sciebo.de/s/7SzJ55ZroKPf5zY/download -O trainingdata/group01.zip

wget --no-check-certificate --content-disposition https://api.ngc.nvidia.com/v2/models/nvidia/research/stylegan3/versions/1/files/stylegan3-t-afhqv2-512x512.pkl -O datasets/stylegan3-t-afhqv2-512x512.pkl

https://api.ngc.nvidia.com/v2/models/nvidia/research/stylegan3/versions/1/files/stylegan3-t-afhqv2-512x512.pkl

Prepare training data

Before training, it is highly recommended to check your dataset through the given stylegan3 check-up. It can resize your images too, although it is usually better to do it before on your own. (Adobe Bridge is a great tool for batch processing.)

python dataset_tool.py --source=trainingdata/group01.zip --destination=dest=trainingdata/group01.zip --resolution=512x512

--source= your directory with the given files
--destination= the output directory, dont forget to add .zip at the end
--resolution= resolution you want your images to be saved in. (1024x1024, 512x512 or 256x256 resolution)

start training

python train.py --outdir=~/training-runs --cfg=stylegan3-t --data=~/datasets/afhqv2-512x512.zip --gpus=8 --batch=32 --gamma=8.2 --mirror=1

--outdir= direction where you want to save the trained data
--data= your dataset you want to use
--gpus= depends on the gpus you have. usually 1 will be
--batch=

python train.py --outdir=~/training-runs --cfg=stylegan3-t --data=~/trainingdata/(...)  --gpus=1 --batch=8 --gamma=2 --snap=20 --resume=~/datasets/afhqv2-512x512.zip

Opening the Python Visualizer

Python Visualizer

The following script will open the python Visualizer

python visualizer.py

You can open one of the .pkl files that NVIDIA provided or paste a local URL to your own trainingdata to visualize and play around.
