News

• 17 April 2020. Created Slack community. Please join via invitation link.
• 15 April 2020. Added StyleGAN-generated avatars. Just press Q and now you drive a person that never existed. Every time you push the button – new avatar is sampled.
• 13 April 2020. Added Windows support (kudos to 9of9).

Requirements

To run Avatarify smoothly you need a CUDA-enabled (NVIDIA) video card. Otherwise it will fallback to the central processor and run very slowly. These are performance metrics for some hardware:

• GeForce GTX 1080 Ti: 33 fps
• GeForce GTX 1070: 15 fps
• Mac OSX (MacBook Pro 2018; no GPU): very slow ~1 fps

Of course, you also need a webcam!

Install

Download network weights

Download model's weights from Yandex.Disk or Google Drive [716 MB, md5sum 46b26eabacbcf1533ac66dc5cf234c5e]

Linux

Linux uses v4l2loopback to create virtual camera.

• Download Miniconda Python 3.7 and install using command:

bash Miniconda3-latest-Linux-x86_64.sh

• Clone avatarify and install its dependencies (sudo privelege is required):

git clone https://github.com/alievk/avatarify.git
cd avatarify
bash scripts/install.sh

• Download network weights and place vox-adv-cpk.pth.tar file in the avatarify directory (don't unpack it).

Mac

(!) Note: we found out that in versions after v4.6.8 (March 23, 2020) Zoom disabled support for virtual cameras on both Mac and Windows. Please, install Zoom v4.6.8 which is the last version that supports virtual cameras.

For Mac it's quite difficult to create a virtual camera, so we'll use CamTwist app:

1. Download and install CamTwist from here. It's easy.
2. Setup avatarify conda environment with all required dependencies:

source scripts/install_mac.sh

3. Download network weights and place vox-adv-cpk.pth.tar file in the avatarify directory (don't unpack it).

Windows

Video tutorial is coming!

This guide is tested for Windows 10.

1. Install Miniconda for Windows.
2. Install Git.
3. Press Windows button and type "miniconda". Run suggested Anaconda Prompt.
4. Download and install Avatarify (please copy-paste these commands and don't change them):

git clone https://github.com/alievk/avatarify.git
cd avatarify
scripts\install_windows.bat

5. Download network weights and place vox-adv-cpk.pth.tar file in the avatarify directory (don't unpack it).
6. Run run_windows.bat. If installation was successful, two windows "cam" and "avatarify" will appear. Leave these windows open for the next installation steps. If there are multiple cameras (including virtual ones) in the system, you may need to select the correct one. Open scripts/settings_windows.bat and edit CAMID variable. CAMID is an index number of camera like 0, 1, 2, ...
7. Install OBS Studio for capturing Avatarify output.
8. Install VirtualCam plugin. Choose Install and register only 1 virtual camera.
9. Run OBS Studio.
10. In the Sources section, press on Add button ("+" sign), select Windows Capture and press OK. In the appeared window, choose "[python.exe]: avatarify" in Window drop-down menu and press OK. Then select Edit -> Transform -> Fit to screen.
11. In OBS Studio, go to Tools -> VirtualCam. Check AutoStart, set Buffered Frames to 0 and press Start.
12. Now OSB-Camera camera should be available in Zoom (or other videoconferencing software).

The steps 10-11 are required only once during setup.

Setup avatars

Copy your avatars into avatars folder. Crop pictures to make them square. Prefer pictures with uniform background.

Run

Your web cam must be plugged-in.

Note: run Skype or Zoom only after Avatarify is started.

Linux

It is supposed that there is only one web cam connected to the computer at /dev/video0. The run script will create virtual camera /dev/video9. You can change these settings in scripts/settings.sh.

You can use command v4l2-ctl --list-devices to list all devices in your system. For example, if the web camera is /dev/video1 then the device id is 1.

Run:

bash run.sh

Mac

1. Run:

bash run_mac.sh

2. Go to CamTwist.
3. Choose Desktop+ and press Select.
4. In the Settings section choose Confine to Application Window and select python (avatarify) from the drop-down menu.

Windows

If there are multiple cameras (including virtual ones) in your system, you may need to select the correct one in scripts/settings_windows.bat. Open this file and edit CAMID variable. CAMID is an index number of camera like 0, 1, 2, ...

1. In Anaconda Prompt:

cd C:\path\to\avatarify
run_windows.bat

2. Run OBS Studio. It should automaitcally start streaming video from Avatarify to OBS-Camera.

Note: To reduce video latency, in OBS Studio right click on the preview window and uncheck Enable Preview.

Controls

Keys	Controls
1-9	These will immediately switch between the first 9 avatars.
Q	Turns on StyleGAN-generated avatar. Every time you push the button – new avatar is sampled.
0	Toggles avatar display on and off.
A/D	Previous/next avatar in folder.
W/S	Zoom camera in/out.
Z/C	Adjust avatar target overlay opacity.
X	Reset reference frame.
F	Toggle reference frame search mode.
R	Mirror reference window.
T	Mirror output window.
ESC	Quit

Driving your avatar

It is recommended to use the avatar overlay and the zoom in/out function to align your face in the preview window as closely as possible in proportion and position to the target avatar. When you have aligned, hit 'X' to use this frame as reference to drive the rest of the animation.

Alternatively, you can hit 'F' for the software to attempt to find a better reference frame itself. This will slow down the framerate, but while this is happening, you can keep moving your head around: the preview window will flash green when it finds your facial pose is a closer match to the avatar than the one it is currently using. You will see two numbers displayed as well: the first number is how closely you are currently aligned to the avatar, and the second number is how closely the reference frame is aligned.

You want to get the first number as small as possible - around 10 is usually a good alignment. When you are done, press 'F' again to exit reference frame search mode.

You don't need to be exact, and some other configurations can yield better results still, but it's usually a good starting point.

Configure video meeting app

Skype

Go to Settings -> Audio & Video, choose avatarify (Linux), CamTwist (Mac) or OBS-Camera (Windows) camera.

Zoom

Go to Settings -> Video and choose avatarify (Linux), CamTwist (Mac) or OBS-Camera (Windows) from Camera drop-down menu.

Slack

Make a call, allow browser using cameras, click on Settings icon, choose avatarify (Linux), CamTwist (Mac) or OBS-Camera (Windows) in Video settings drop-down menu.

Contribution

Our goal is to democratize deepfake avatars. To make the technology even more accessible, we have to tackle two major problems:

1. Add support for more platforms (Linux and Mac are already supported).
2. Optimize neural network run-time. Running network real-time on CPU is of high priority.

Please make pull requests if you have any improvements or bug-fixes.

Troubleshooting

• Zoom/Skype doesn't see avatarify camera. Restart Zoom/Skype and try again.
• Avatar image is frozen: In Zoom, try Stop and Start Video.
• bash run_mac.sh crashes with "Cannot open camera": Try to change CAMID in run_mac.sh from 0 to 1, 2, ...
• pipe:0: Invalid data found when processing input: Make sure CAMID in scripts/settings.sh is correct. Use v4l2-ctl --list-devices to query available devices.
• ASSERT: "false" in file qasciikey.cpp, line 501. If you have several keyboard layouts, switch to English layout.
• No such file or directory: 'vox-adv-cpk.pth.tar'. Please follow instructions Download network weights
