Steps:
Set Up the Environment:
- Clone the AI Toolkit repository from GitHub:
git clone https://github.com/ostris/ai-toolkit
- Install required dependencies:
cd ai-toolkit pip install -r requirements.txt
- Clone the AI Toolkit repository from GitHub:
Prepare the Dataset:
- Organize your images and text prompts into a structured format, such as JSON or CSV or Directory.
- Ensure that the image filenames match the corresponding text prompts.
- Consider using a data augmentation technique to increase the diversity of your training data.
Configure the Training Script:
- Open the
train_lora_flux_24gb.py
script in your preferred text editor. - Modify the following parameters:
model_path
: Path to the pre-trained Flux.1 model.data_path
: Path to your dataset.output_dir
: Directory where the fine-tuned model will be saved.train_batch_size
: Batch size for training.eval_batch_size
: Batch size for evaluation.num_epochs
: Number of training epochs.learning_rate
: Learning rate.lora_rank
: Rank of the LoRA layers.lora_alpha
: Scaling factor for the LoRA layers.save_every
: Frequency of saving checkpoints.
- Open the
Start the Training:
- Run the training script:
python train_lora_flux_24gb.py
- The training process may take several hours or even days, depending on the size of your dataset and the hardware you're using.
- Run the training script:
Evaluate the Fine-Tuned Model:
- Generate images using the fine-tuned model and compare the results to the original model.
- Assess the quality of the generated images based on your specific requirements.
Additional Tips:
- Experiment with different hyperparameters: Adjust the learning rate, batch size, and other parameters to optimize the training process.
- Consider using a learning rate scheduler: This can help prevent overfitting and improve convergence.
- Monitor the training progress: Keep an eye on the loss function and evaluation metrics to ensure that the model is learning effectively.
- Share your fine-tuned model: Contribute to the community by sharing your trained model with others.
By following these steps and incorporating the additional tips, you can effectively fine-tune Flux.1 using the AI Toolkit to achieve your desired image generation goals.
What is the recommended dataset size for fine-tuning Flux.1 effectively?
The recommended dataset size for fine-tuning Flux.1 can vary based on the complexity and goals of the project. However, starting with a small, high-quality dataset of 10 to 15 well-prepared images is often enough for simpler tasks like personalized image generation. This dataset should contain diverse images (varied angles, lighting, and expressions) to ensure better fine-tuning results.
For more complex models or broader applications, a larger dataset may be required to capture a wider range of features.
hey @exnrt - would love to get your feedback on our fine-tuning on astria.ai - i think the results are really good
how to load the flux model after finetune using ai-toolkit? In other words, how to merge lora checkpoint to the original flux dev model?
