Abstract: Inspired by the ability of StyleGAN to generate highly realistic images in a variety of domains, much recent work has focused on understanding how to use the latent spaces of StyleGAN to manipulate generated and real images. However, discovering semantically meaningful latent manipulations typically involves painstaking human examination of the many degrees of freedom, or an annotated collection of images for each desired manipulation. In this work, we explore leveraging the power of recently introduced Contrastive Language-Image Pre-training (CLIP) models in order to develop a text-based interface for StyleGAN image manipulation that does not require such manual effort. We first introduce an optimization scheme that utilizes a CLIP-based loss to modify an input latent vector in response to a user-provided text prompt. Next, we describe a latent mapper that infers a text-guided latent manipulation step for a given input image, allowing faster and more stable textbased manipulation. Finally, we present a method for mapping a text prompts to input-agnostic directions in StyleGAN’s style space, enabling interactive text-driven image manipulation. Extensive results and comparisons demonstrate the effectiveness of our approaches.


Official Implementation of StyleCLIP, a method to manipulate images using a driving text. Our method uses the generative power of a pretrained StyleGAN generator, and the visual-language power of CLIP. In the paper we present three methods:

  • Latent vector optimization.
  • Latent mapper, trained to manipulate latent vectors according to a specific text description.
  • Global directions in the StyleSpace.

Setup (for all three methods)

For all the methods described in the paper, is it required to have:

Specific requirements for each method are described in its section. To install CLIP please run the following commands:

conda install --yes -c pytorch pytorch=1.7.1 torchvision cudatoolkit=<CUDA_VERSION>
pip install ftfy regex tqdm gdown
pip install git+

Editing via Latent Vector Optimization


Here, the code relies on the Rosinality pytorch implementation of StyleGAN2. Some parts of the StyleGAN implementation were modified, so that the whole implementation is native pytorch.

In addition to the requirements mentioned before, a pretrained StyleGAN2 generator will attempt to be downloaded, (or manually download from here).


Given a textual description, one can both edit a given image, or generate a random image that best fits to the description. Both operations can be done through the script, or the optimization_playground.ipynb notebook (Open In Colab).


To edit an image set --mode=edit. Editing can be done on both provided latent vector, and on a random latent vector from StyleGAN's latent space. It is recommended to adjust the --l2_lambda according to the desired edit.

Generating Free-style Images

To generate a free-style image set --mode=free_generation.

Editing via Latent Mapper

Here, we provide the code for the latent mapper. The mapper is trained to learn residuals from a given latent vector, according to the driving text. The code for the mapper is in mapper/.


As in the optimization, the code relies on Rosinality pytorch implementation of StyleGAN2. In addition the the StyleGAN weights, it is neccessary to have weights for the facial recognition network used in the ID loss. The weights can be downloaded from here.

The mapper is trained on latent vectors. It is recommended to train on inverted real images. To this end, we provide the CelebA-HQ that was inverted by e4e: train set, test set.



  • The main training script is placed in mapper/scripts/
  • Training arguments can be found at mapper/options/
  • Intermediate training results are saved to opts.exp_dir. This includes checkpoints, train outputs, and test outputs. Additionally, if you have tensorboard installed, you can visualize tensorboard logs in opts.exp_dir/logs. Note that
  • To resume a training, please provide --checkpoint_path.
  • --description is where you provide the driving text.
  • If you perform an edit that is not supposed to change "colors" in the image, it is recommended to use the flag --no_fine_mapper.

Example for training a mapper for the moahwk hairstyle:

cd mapper
python --exp_dir ../results/mohawk_hairstyle --no_fine_mapper --description "mohawk hairstyle"

All configurations for the examples shown in the paper are provided there.


  • The main inferece script is placed in mapper/scripts/
  • Inference arguments can be found at mapper/options/
  • Adding the flag --couple_outputs will save image containing the input and output images side-by-side.

Pretrained models for variuos edits are provided. Please refer to for the complete links list.

We also provide a notebook for performing inference with the mapper Mapper notebook: Open In Colab

Editing via Global Direction

Here we provide GUI for editing images with the global directions. We provide both a jupyter notebook Open In Colab, and the GUI used in the video. For both, the linear direction are computed in real time. The code is located at global_directions/.


Here, we rely on the official TensorFlow implementation of StyleGAN2.

It is required to have TensorFlow, version 1.14 or 1.15 (conda install -c anaconda tensorflow-gpu==1.14).


Local GUI

To start the local GUI please run the following commands:

cd global_directions

# input dataset name 

# pretrained StyleGAN2 model from standard [NVlabs implementation]( will be download automatically.
# pretrained StyleGAN2-ada model could be download from .
# for custom StyleGAN2 or StyleGAN2-ada model, please place the model under ./StyleCLIP/global_directions/model/ folder.

# input prepare data 
python --dataset_name $dataset_name --code_type 'w'
python --dataset_name $dataset_name --code_type 's'
python --dataset_name $dataset_name --code_type 's_mean_std'

# preprocess (this may take a few hours). 
# we precompute the results for StyleGAN2 on ffhq, StyleGAN2-ada on afhqdog, afhqcat. For these model, we can skip the preprocess step.
python --dataset_name $dataset_name

# generated image to be manipulated 
# this operation will generate and replace the w_plu.npy and .jpg images in './data/dataset_name/' folder. 
# if you you want to keep the original data, please rename the original folder.
# to use custom images, please use e4e encoder to generate, and place it in './data/dataset_name/' folder, and add --real flag while running this function.
# you may skip this step if you want to manipulate the real human faces we prepare in ./data/ffhq/ folder.   
python --dataset_name $dataset_name

# interactively manipulation 
python --dataset_name $dataset_name

As shown in the video, to edit an image it is requires to write a neutral text and a target text. To operate the GUI, please do the following:

  • Maximize the window size
  • Double click on the left square to choose an image. The images are taken from global_directions/data/ffhq, and the corresponding latent vectors are in global_directions/data/ffhq/w_plus.npy.
  • Type a neutral text, then press enter
  • Modify the target text so that it will contain the target edit, then press enter.

You can now play with:

  • Manipulation strength - positive values correspond to moving along the target direction.
  • Disentanglement threshold - large value means more disentangled edit, just a few channels will be manipulated so only the target attribute will change (for example, grey hair). Small value means less disentangled edit, a large number of channels will be manipulated, related attributes will also change (such as wrinkle, skin color, glasses).
Edit Neutral Text Target Text
Smile face smiling face
Gender female face male face
Blonde hair face with hair face with blonde hair
Hi-top fade face with hair face with Hi-top fade hair
Blue eyes face with eyes face with blue eyes

More examples could be found in the video and in the paper.

Pratice Tips:

In the terminal, for every manipulation, the number of channels being manipulated is printed (the number is controlled by the attribute (neutral, target) and the disentanglement threshold).

  1. For color transformation, usually 10-20 channels is enough. For large structure change (for example, Hi-top fade), usually 100-200 channels are required.
  2. For an attribute (neutral, target), if you give a low disentanglement threshold, there are just few channels (<20) being manipulated, and usually it is not enough for performing the desired edit.


Open the notebook in colab and run all the cells. In the last cell you can play with the image.

beta corresponds to the disentanglement threshold, and alpha to the manipulation strength.

After you set the desired set of parameters, please run again the last cell to generate the image.

Editing Examples

In the following, we show some results obtained with our methods. All images are real, and were inverted into the StyleGAN's latent space using e4e. The driving text that was used for each edit appears below or above each image.

Latent Optimization

Latent Mapper

Global Directions

The global directions we find for editing are direction in the S Space, which was introduced and analyzed in StyleSpace (Wu et al).

To edit real images, we inverted them to the StyleGAN's latent space using e4e (Tov et al.).

The code strcuture of the mapper is heavily based on pSp.
