Kohya's GUI

This repository primarily provides a Gradio GUI for Kohya's Stable Diffusion trainers. However, support for Linux OS is also offered through community contributions. macOS support is not optimal at the moment but might work if the conditions are favorable.

The GUI allows you to set the training parameters and generate and run the required CLI commands to train the model.

Installation

Windows

Windows Pre-requirements

To install the necessary dependencies on a Windows system, follow these steps:

  1. Install Python 3.10.11.

    • During the installation process, ensure that you select the option to add Python to the 'PATH' environment variable.

  2. Install CUDA 11.8 toolkit.

  3. Install Git.

  4. Install the Visual Studio 2015, 2017, 2019, and 2022 redistributable.

Setup Windows

To set up the project, follow these steps:

  1. Open a terminal and navigate to the desired installation directory.

  2. Clone the repository by running the following command:

    git clone https://github.com/bmaltais/kohya_ss.git

  3. Change into the kohya_ss directory:

    cd kohya_ss

  4. Run the setup script by executing the following command:

    .\setup.bat

    During the accelerate config step, use the default values as proposed during the configuration unless you know your hardware demands otherwise. The amount of VRAM on your GPU does not impact the values used.

Optional: CUDNN 8.9.6.50

The following steps are optional but will improve the learning speed for owners of NVIDIA 30X0/40X0 GPUs. These steps enable larger training batch sizes and faster training speeds.

  1. Run .\setup.bat and select 2. (Optional) Install cudnn files (if you want to use the latest supported cudnn version).

Linux and macOS

Linux Pre-requirements

To install the necessary dependencies on a Linux system, ensure that you fulfill the following requirements:

  • Ensure that venv support is pre-installed. You can install it on Ubuntu 22.04 using the command:

    apt install python3.10-venv

  • Install the CUDA 11.8 Toolkit by following the instructions provided in this link.

  • Make sure you have Python version 3.10.9 or higher (but lower than 3.11.0) installed on your system.

Setup Linux

To set up the project on Linux or macOS, perform the following steps:

  1. Open a terminal and navigate to the desired installation directory.

  2. Clone the repository by running the following command:

    git clone https://github.com/bmaltais/kohya_ss.git

  3. Change into the kohya_ss directory:

    cd kohya_ss

  4. If you encounter permission issues, make the setup.sh script executable by running the following command:

    chmod +x ./setup.sh

  5. Run the setup script by executing the following command:

    ./setup.sh

    Note: If you need additional options or information about the runpod environment, you can use setup.sh -h or setup.sh --help to display the help message.

Install Location

The default installation location on Linux is the directory where the script is located. If a previous installation is detected in that location, the setup will proceed there. Otherwise, the installation will fall back to /opt/kohya_ss. If /opt is not writable, the fallback location will be $HOME/kohya_ss. Finally, if none of the previous options are viable, the installation will be performed in the current directory.

For macOS and other non-Linux systems, the installation process will attempt to detect the previous installation directory based on where the script is run. If a previous installation is not found, the default location will be $HOME/kohya_ss. You can override this behavior by specifying a custom installation directory using the -d or --dir option when running the setup script.

If you choose to use the interactive mode, the default values for the accelerate configuration screen will be "This machine," "None," and "No" for the remaining questions. These default answers are the same as the Windows installation.

Runpod

Manual installation

To install the necessary components for Runpod and run kohya_ss, follow these steps:

  1. Select the Runpod pytorch 2.0.1 template. This is important. Other templates may not work.

  2. SSH into the Runpod.

  3. Clone the repository by running the following command:

    cd /workspace
git clone https://github.com/bmaltais/kohya_ss.git

  4. Run the setup script:

    cd kohya_ss
./setup-runpod.sh

  5. Run the GUI with:

    ./gui.sh --share --headless

    or with this if you expose 7860 directly via the runpod configuration:

    ./gui.sh --listen=0.0.0.0 --headless

  6. Connect to the public URL displayed after the installation process is completed.

Pre-built Runpod template

To run from a pre-built Runpod template, you can:

  1. Open the Runpod template by clicking on https://runpod.io/gsc?template=ya6013lj5a&ref=w18gds2n.

  2. Deploy the template on the desired host.

  3. Once deployed, connect to the Runpod on HTTP 3010 to access the kohya_ss GUI. You can also connect to auto1111 on HTTP 3000.

Docker

Local docker build

If you prefer to use Docker, follow the instructions below:

  1. Ensure that you have Git and Docker installed on your Windows or Linux system.

  2. Open your OS shell (Command Prompt or Terminal) and run the following commands:

    git clone --recursive https://github.com/bmaltais/kohya_ss.git
cd kohya_ss
docker compose up -d --build

    Note: The initial run may take up to 20 minutes to complete.

    Please be aware of the following limitations when using Docker:

    • All training data must be placed in the dataset subdirectory, as the Docker container cannot access files from other directories.
    • The file picker feature is not functional. You need to manually set the folder path and config file path.
    • Dialogs may not work as expected, and it is recommended to use unique file names to avoid conflicts.
    • This Dockerfile has been designed to be easily disposable. You can discard the container at any time and docker build it with a new version of the code. To update the system, run update scripts outside of Docker and rebuild using docker compose down && docker compose up -d --build.

    If you are running Linux, an alternative Docker container port with fewer limitations is available here.

  2. Pull the latest changes from the repository:

    git pull

  3. Refresh and update everything:

    ./setup.sh

Starting GUI Service

To launch the GUI service, you can use the provided scripts or run the kohya_gui.py script directly. Use the command line arguments listed below to configure the underlying service.

--listen: Specify the IP address to listen on for connections to Gradio.
--username: Set a username for authentication.
--password: Set a password for authentication.
--server_port: Define the port to run the server listener on.
--inbrowser: Open the Gradio UI in a web browser.
--share: Share the Gradio UI.
--language: Set custom language

Launching the GUI on Windows

On Windows, you can use either the gui.ps1 or gui.bat script located in the root directory. Choose the script that suits your preference and run it in a terminal, providing the desired command line arguments. Here's an example:

gui.ps1 --listen 127.0.0.1 --server_port 7860 --inbrowser --share

or

gui.bat --listen 127.0.0.1 --server_port 7860 --inbrowser --share

Launching the GUI on Linux and macOS

To launch the GUI on Linux or macOS, run the gui.sh script located in the root directory. Provide the desired command line arguments as follows:

gui.sh --listen 127.0.0.1 --server_port 7860 --inbrowser --share

Custom Path Defaults

The repository now provides a default configuration file named config.toml. This file is a template that you can customize to suit your needs.

To use the default configuration file, follow these steps:

  1. Copy the config example.toml file from the root directory of the repository to config.toml.
  2. Open the config.toml file in a text editor.
  3. Modify the paths and settings as per your requirements.

This approach allows you to easily adjust the configuration to suit your specific needs to open the desired default folders for each type of folder/file input supported in the GUI.

You can specify the path to your config.toml (or any other name you like) when running the GUI. For instance: ./gui.bat --config c:\my_config.toml

LoRA

To train a LoRA, you can currently use the train_network.py code. You can create a LoRA network by using the all-in-one GUI.

Once you have created the LoRA network, you can generate images using auto1111 by installing this extension.

Sample image generation during training

A prompt file might look like this, for example:

# prompt 1
masterpiece, best quality, (1girl), in white shirts, upper body, looking at viewer, simple background --n low quality, worst quality, bad anatomy, bad composition, poor, low effort --w 768 --h 768 --d 1 --l 7.5 --s 28

# prompt 2
masterpiece, best quality, 1boy, in business suit, standing at street, looking back --n (low quality, worst quality), bad anatomy, bad composition, poor, low effort --w 576 --h 832 --d 2 --l 5.5 --s 40

Lines beginning with # are comments. You can specify options for the generated image with options like --n after the prompt. The following options can be used:

  • --n: Negative prompt up to the next option.
  • --w: Specifies the width of the generated image.
  • --h: Specifies the height of the generated image.
  • --d: Specifies the seed of the generated image.
  • --l: Specifies the CFG scale of the generated image.
  • --s: Specifies the number of steps in the generation.

The prompt weighting such as ( ) and [ ] is working.

Troubleshooting

If you encounter any issues, refer to the troubleshooting steps below.

Page File Limit

If you encounter an X error related to the page file, you may need to increase the page file size limit in Windows.

No module called tkinter

If you encounter an error indicating that the module tkinter is not found, try reinstalling Python 3.10 on your system.

LORA Training on TESLA V100 - GPU Utilization Issue

Issue Summary

When training LORA on a TESLA V100, users reported low GPU utilization. Additionally, there was difficulty in specifying GPUs other than the default for training.

Potential Solutions

  • GPU Selection: Users can specify GPU IDs in the setup configuration to select the desired GPUs for training.
  • Improving GPU Load: Utilizing adamW8bit optimizer and increasing the batch size can help achieve 70-80% GPU utilization without exceeding GPU memory limits.

SDXL training

The documentation in this section will be moved to a separate document later.

Masked loss

The masked loss is supported in each training script. To enable the masked loss, specify the --masked_loss option.

The feature is not fully tested, so there may be bugs. If you find any issues, please open an Issue.

ControlNet dataset is used to specify the mask. The mask images should be the RGB images. The pixel value 255 in R channel is treated as the mask (the loss is calculated only for the pixels with the mask), and 0 is treated as the non-mask. The pixel values 0-255 are converted to 0-1 (i.e., the pixel value 128 is treated as the half weight of the loss). See details for the dataset specification in the LLLite documentation.

New Contributors

2024/04/24 (v24.0.3)

  • Fix issue with sample prompt creation

2024/04/24 (v24.0.2)

  • Fixed issue with clip_skip not being passed as an int to sd-scripts when using old config.json files.

2024/04/17 (v24.0.1)

Enhancements

  • User Interface: Transitioned the GUI to use a TOML file for argument passing to sd-scripts, significantly enhancing security by eliminating the need for command-line interface (CLI) use for sensitive data.
  • Training Tools: Improved the training and TensorBoard buttons to provide a more intuitive user experience.
  • HuggingFace Integration: Integrated a HuggingFace section in all trainer tabs, enabling authentication and use of HuggingFace's advanced AI models.
  • Gradio Upgrade: Upgraded Gradio to version 4.20.0 to fix a previously identified bug impacting the runpod platform.
  • Metadata Support: Added functionality for metadata capture within the GUI.

Security and Stability

  • Code Refactoring: Extensively rewrote the code to address various security vulnerabilities, including removing the shell=True parameter from process calls.
  • Scheduler Update: Disabled LR Warmup when using the Constant LR Scheduler to prevent traceback errors associated with sd-scripts.

Shell Execution

  • Conditional Shell Usage: Added support for optional shell usage when executing external sd-scripts commands, tailored to meet specific platform needs and recent security updates.

The gui.bat and gui.sh scripts now include the --do_not_use_shell argument to prevent shell execution (shell=True) during external process handling.The GUI will automatically set use_shell to True internally, as required for proper execution of external commands. To enforce disabling shell execution, use the --do_not_use_shell argument.

  • How to Enable Shell Execution via Config File:
    1. In the config.toml file, set use_shell to true to enable shell usage as per GUI startup settings. Note: The --do_not_use_shell option will override the config.toml settings, setting use_shell to False even if it is set to True in the config file.

Miscellaneous

    • About Masked loss The masked loss is supported in each training script. To enable the masked loss, specify the --masked_loss option.

      The feature is not fully tested, so there may be bugs. If you find any issues, please open an Issue.

      ControlNet dataset is used to specify the mask. The mask images should be the RGB images. The pixel value 255 in R channel is treated as the mask (the loss is calculated only for the pixels with the mask), and 0 is treated as the non-mask. The pixel values 0-255 are converted to 0-1 (i.e., the pixel value 128 is treated as the half weight of the loss). See details for the dataset specification in the LLLite documentation.

    • About Scheduled Huber Loss Scheduled Huber Loss has been introduced to each training scripts. This is a method to improve robustness against outliers or anomalies (data corruption) in the training data.

      With the traditional MSE (L2) loss function, the impact of outliers could be significant, potentially leading to a degradation in the quality of generated images. On the other hand, while the Huber loss function can suppress the influence of outliers, it tends to compromise the reproduction of fine details in images.

      To address this, the proposed method employs a clever application of the Huber loss function. By scheduling the use of Huber loss in the early stages of training (when noise is high) and MSE in the later stages, it strikes a balance between outlier robustness and fine detail reproduction.

      Experimental results have confirmed that this method achieves higher accuracy on data containing outliers compared to pure Huber loss or MSE. The increase in computational cost is minimal.

      The newly added arguments loss_type, huber_schedule, and huber_c allow for the selection of the loss function type (Huber, smooth L1, MSE), scheduling method (exponential, constant, SNR), and Huber's parameter. This enables optimization based on the characteristics of the dataset.

      See PR #1228 for details.

      • loss_type: Specify the loss function type. Choose huber for Huber loss, smooth_l1 for smooth L1 loss, and l2 for MSE loss. The default is l2, which is the same as before.
      • huber_schedule: Specify the scheduling method. Choose exponential, constant, or snr. The default is snr.
      • huber_c: Specify the Huber's parameter. The default is 0.1.

      Please read Releases for recent updates.`

  • Added GUI support for the new parameters listed above.

  • Moved accelerate launch parameters to a new Accelerate launch accordion above the Model accordion.

  • Added support for Debiased Estimation loss to Dreambooth settings.

  • Added support for "Dataset Preparation" defaults via the config.toml file.

  • Added a field to allow for the input of extra accelerate launch arguments.

  • Added new caption tool from https://github.com/kainatquaderee
