# Activate the virtual environment
$ source venv/bin/activate

Additional Linux Packages (if needed)

Depending on your Linux distribution, you may need to install additional system-level dependencies:

# Install necessary system packages (Debian/Ubuntu)
$ sudo apt-get update
$ sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

Installation on Windows

Clone the Repository

# Clone the repository
$ git clone https://github.com/ostris/ai-toolkit.git
 
# Change directory to the repository
$ cd ai-toolkit

Install the Dependencies

# Install the required dependencies
$ git submodule update --init --recursive
$ pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121
$ pip install -r requirements.txt

Set Up Virtual Environment (Optional)

# Create a virtual environment
$ python -m venv venv
 
# Activate the virtual environment
$ venv\Scripts\activate

After installing the dependencies, you should be ready to start experimenting. Ensure that you are using a Python environment compatible with the toolkit to avoid dependency issues. Consider using tools like virtualenv to manage your environment.

Running Your First Experiment

Once the toolkit is set up, you can run your first experiment by using the following command:

# Train a model using default settings
$ python run.py --config configs/default.yaml

Feel free to modify the configuration file to suit your research needs. The toolkit also supports more advanced configurations to run hyperparameter tuning and distributed training sessions.

FLUX.1 Training: The New Feature

The AI Toolkit now supports FLUX.1 Training, an optimized training loop designed to accelerate model convergence while maintaining stability. To utilize this feature, ensure you are using the latest version of the toolkit. Here’s how you can run a training session with FLUX.1:

# Train a model using FLUX.1
$ python run.py --config configs/flux1.yaml --use-flux

FLUX.1 leverages advanced optimization techniques, such as learning rate warmups and gradient clipping, to prevent common training pitfalls like exploding gradients or slow convergence.

Advanced Experiment Setup

To run an advanced experiment, you might want to tweak some settings or use different models:

# Example: Run training with a custom config file and log the results
$ python run.py --config configs/custom.yaml --logdir logs/experiment_1

You can further integrate TensorBoard to monitor your training process visually:

# Launch TensorBoard to visualize training metrics
$ tensorboard --logdir logs/

This kind of setup makes it easy to understand model behaviors and make data-driven decisions.

The AI Toolkit also supports running experiments on cloud-based platforms like Modal and RunPod to take advantage of their powerful GPU instances.

Modal is a serverless platform that allows you to run your machine learning workloads seamlessly. Here’s how to set up and run an experiment using Modal:

Install Modal CLI

# Install the Modal CLI tool
$ pip install modal-cli

Login and Set Up Modal

# Log in to your Modal account
$ modal login
 
# Deploy your AI Toolkit to Modal
$ modal deploy ai-toolkit

Run Experiments

After deploying the AI Toolkit to Modal, you can easily start running experiments:

# Run a training job on Modal
$ modal run run.py --config configs/default.yaml

Using Modal allows you to effortlessly scale your experiments without managing physical hardware.

Running on RunPod

RunPod is another excellent service that offers on-demand GPU cloud resources. Here’s how to set up and run an experiment on RunPod:

Create a RunPod Account

Visit RunPod.io and create an account. Once registered, you can create a new pod to launch your environment.
Configure Your Pod

Select the appropriate GPU and environment settings for your AI Toolkit. Ensure that you configure the pod with a compatible Docker image that supports all dependencies.

Connect and Run

Once your pod is running, you can SSH into the environment and start running experiments:

# SSH into your RunPod environment
$ ssh user@runpod-ip-address
 
# Navigate to your project directory
$ cd ai-toolkit
 
# Run a training experiment
$ python run.py --config configs/default.yaml

RunPod is ideal for users who need a flexible, powerful cloud solution to train models without the hassle of hardware setup.

Troubleshooting Common Issues

As this toolkit is heavily experimental, you might encounter bugs or broken features. Here are some common troubleshooting tips:

Issue: Missing Dependencies
- Solution: Make sure to install all the dependencies listed in requirements.txt. You might also need to update your Python version.
Issue: Broken Features After Update
- Solution: Roll back to an earlier commit by using Git commands like git checkout <commit_hash>. This will help you use a more stable version of the toolkit.
Issue: Configuration Errors
- Solution: Double-check your configuration files for syntax errors. YAML is particularly sensitive to indentation.
Issue: Performance Bottlenecks
- Solution: Use profiling tools like PyTorch Profiler to identify and optimize slow parts of your model or data pipeline. Consider upgrading your hardware or using cloud-based GPU resources for demanding tasks.

Tips for Effective Research

Here are a few tips that can help you get the most out of the AI Toolkit:

Use Version Control: As you experiment with new features and models, make sure to use Git branches effectively. This will help you manage different stages of your research without the risk of losing stable code.
Document Everything: Keep thorough documentation of your experiments. This can include changes in the configuration, parameter tweaks, or even unexpected results. The more organized your notes, the easier it is to reproduce and share results.
Collaborate and Share Insights: AI research is often collaborative. Using tools like Jupyter Notebooks or integrating with a platform like Hugging Face Spaces can help you share and demonstrate your findings effectively.
