Training Your HunyuanVideo LoRA: A Step-by-Step Guide
1. Set the Dataset Name
When initiating the dataset creation, naming it appropriately is of utmost importance. Opt for a name that is straightforward, provides a clear indication of the dataset's content, and is easy to recall. Steering clear of special characters and spaces is recommended to prevent potential glitches down the line. For instance, if your dataset comprises images of beautiful sunsets, a fitting name could be âSunsetImageDataset_01â.Let's name it âtestâ this time.
2. Upload Dataset Images
Once you've settled on a name, it's time to upload your dataset images. To ensure the highest quality of the resulting LoRA, it is highly recommended that you upload high-definition, background-clean, 1024*1024 image materials. These specifications help the model capture finer details and patterns, leading to more accurate and impressive training outcomes. Additionally, make sure your dataset contains no fewer than 10 images. A larger and more diverse dataset generally enables the model to learn a broader range of features, enhancing its generalization ability.
Post-upload, the system will automatically generate the requisite files.
Here's a critical point to bear in mind: these files must be devoid of Chinese or any other non-English characters. This precautionary measure guarantees hitch-free processing and seamless compatibility throughout the training odyssey.
Regarding parameter settings, you're presented with the option to select from pre-installed models. However, if you're inclined to train based on models not included by default, here's the drill:
- Upload the Hunyuan corresponding model and VAE model to the models directory.
- Modify the model name, being cautious to only alter the actual name of the model while leaving the preceding preceding path intact. This way, the system can accurately locate and employ the models.
3. Start Training
With all your ducks in a row â settings perfected and dataset primed â you're all set to commence the training process. A simple click on the âstart trainingâ button sets the wheels in motion. The Diffusion-Pip script will then commence its journey through your dataset, deftly applying the chosen model and parameters to sculpt the Hunyuan LoRA.
4. Training End Indicator
To stay informed about the training's progress and ascertain when it concludes, keep a vigilant eye on the outputlogs. The moment you spot the message âSaving model, Training completeâ within the outputlogs, rejoice! Your training has reached fruition. At this juncture, you can navigate to File Storage > outputs and salvage the trained LoRA model to your local storage for future utilization or dissemination.
Conclusion
While using diffusion-pipe to train HunyuanVideo LoRA might initially seem complex, it's a gateway to advanced video generation capabilities. By following these steps meticulously, you'll harness the full model performance potential for generating videos with unprecedented control.
