A repo for running VQGAN+CLIP locally. This started out as a Katherine Crowson VQGAN+CLIP derived Google colab notebook.
Original notebook:
Some example images:
Environment:
- Tested on Ubuntu 20.04
- GPU: Nvidia RTX 3090
- Typical VRAM requirements:
- 24 GB for a 900x900 image
- 10 GB for a 512x512 image
- 8 GB for a 380x380 image

This example uses Anaconda to manage virtual Python environments.
Create a new virtual Python environment for VQGAN-CLIP:
conda create --name vqgan python=3.9
conda activate vqganInstall Pytorch in the new enviroment:
Note: This installs the CUDA version of Pytorch, if you want to use an AMD graphics card, read the AMD section below.
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.htmlInstall other required Python packages:
pip install ftfy regex tqdm omegaconf pytorch-lightning IPython kornia imageio imageio-ffmpeg einops torch_optimizer setuptools==59.5.0Or use the requirements.txt file, which includes version numbers.
Clone required repositories:
git clone 'https://github.com/nerdyrodent/VQGAN-CLIP'
cd VQGAN-CLIP
git clone 'https://github.com/openai/CLIP'
git clone 'https://github.com/CompVis/taming-transformers'Note: In my development environment both CLIP and taming-transformers are present in the local directory, and so aren't present in the requirements.txt or vqgan.yml files.
As an alternative, you can also pip install taming-transformers and CLIP.
You will also need at least 1 VQGAN pretrained model. E.g.
mkdir checkpoints
curl -L -o checkpoints/vqgan_imagenet_f16_16384.yaml -C - 'https://heibox.uni-heidelberg.de/d/a7530b09fed84f80a887/files/?p=%2Fconfigs%2Fmodel.yaml&dl=1' #ImageNet 16384
curl -L -o checkpoints/vqgan_imagenet_f16_16384.ckpt -C - 'https://heibox.uni-heidelberg.de/d/a7530b09fed84f80a887/files/?p=%2Fckpts%2Flast.ckpt&dl=1' #ImageNet 16384Note that users of curl on Microsoft Windows should use double quotes.
The download_models.sh script is an optional way to download a number of models. By default, it will download just 1 model.
See https://github.com/CompVis/taming-transformers#overview-of-pretrained-models for more information about VQGAN pre-trained models, including download links.
By default, the model .yaml and .ckpt files are expected in the checkpoints directory.
See https://github.com/CompVis/taming-transformers for more information on datasets and models.

Note: This hasn't been tested yet.
ROCm can be used for AMD graphics cards instead of CUDA. You can check if your card is supported here: https://github.com/RadeonOpenCompute/ROCm#supported-gpus
Install ROCm accordng to the instructions and don't forget to add the user to the video group: https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html
The usage and set up instructions above are the same, except for the line where you install Pytorch.
Instead of pip install torch==1.9.0+cu111 ..., use the one or two lines which are displayed here (select Pip -> Python-> ROCm):
https://pytorch.org/get-started/locally/
If no graphics card can be found, the CPU is automatically used and a warning displayed.
Regardless of an available graphics card, the CPU can also be used by adding this command line argument: -cd cpu
This works with the CUDA version of Pytorch, even without CUDA drivers installed, but doesn't seem to work with ROCm as of now.
Remove the Python enviroment:
conda remove --name vqgan --alland delete the VQGAN-CLIP directory.
To generate images from text, specify your text prompt as shown in the example below:
python generate.py -p "A painting of an apple in a fruit bowl"
Text and image prompts can be split using the pipe symbol in order to allow multiple prompts. You can also use a colon followed by a number to set a weight for that prompt. For example:
python generate.py -p "A painting of an apple in a fruit bowl | psychedelic | surreal:0.5 | weird:0.25"
Image prompts can be split in the same way. For example:
python generate.py -p "A picture of a bedroom with a portrait of Van Gogh" -ip "samples/VanGogh.jpg | samples/Bedroom.png"Sets of text prompts can be created using the caret symbol, in order to generate a sort of story mode. For example:
python generate.py -p "A painting of a sunflower|photo:-1 ^ a painting of a rose ^ a painting of a tulip ^ a painting of a daisy flower ^ a photograph of daffodil" -cpe 1500 -zvid -i 6000 -zse 10 -vl 20 -zsc 1.005 -opt Adagrad -lr 0.15 -se 6000An input image with style text and a low number of iterations can be used create a sort of "style transfer" effect. For example:
python generate.py -p "A painting in the style of Picasso" -ii samples/VanGogh.jpg -i 80 -se 10 -opt AdamW -lr 0.25| Output | Style |
|---|---|
 |
Picasso |
 |
Sketch |
 |
Psychedelic |
A video style transfer effect can be achived by specifying a directory of video frames in video_style_dir. Output will be saved in the steps directory, using the original video frame filenames. You can also use this as a sort of "batch mode" if you have a directory of images you want to apply a style to. This can also be combined with Story Mode if you don't wish to apply the same style to every images, but instead roll through a list of styles.
By feeding back the generated images and making slight changes, some interesting effects can be created.
The example zoom.sh shows this by applying a zoom and rotate to generated images, before feeding them back in again.
To use zoom.sh, specifying a text prompt, output filename and number of frames. E.g.
./zoom.sh "A painting of a red telephone box spinning through a time vortex" Telephone.png 150If you don't have ImageMagick installed, you can install it with sudo apt install imagemagick
There is also a simple zoom video creation option available. For example:
python generate.py -p "The inside of a sphere" -zvid -i 4500 -zse 20 -vl 10 -zsc 0.97 -opt Adagrad -lr 0.15 -se 4500Use random.sh to make a batch of images from random text. Edit the text and number of generated images to your taste!
./random.shTo view the available options, use "-h".

Your request doesn't fit into your GPU's VRAM. Reduce the image size and/or number of cuts.
