Background
Visual Language Model (VLM) fine-tuning usually requires dealing with a large number of configuration files involving multiple dimensions such as model architecture, hyperparameter settings, and data paths. Traditional methods require manually writing YAML/JSON, which is highly error-prone and time-consuming, and has become a key barrier to non-specialists.
Core Solutions
- Automated Configuration Management: Maestro automatically generates the necessary profiles by pre-built best practice templates for mainstream models (Florence-2/PaliGemma 2, etc.)
- Hierarchical parameter design: Categorize the parameters intomandatory parameter(e.g., dataset paths) andOptional parameters(optimized values are used by default), only 5-7 key parameters need to be entered via CLI
- Configuring the authentication mechanism: Automatically checking the legitimacy of parameters before training starts, avoiding wasted resources due to misconfiguration
concrete operation
One-click configuration via the command line:
maestro paligemma_2 train --dataset "path/to/data" --epochs 10 --batch-size 4
or flexible customization via the Python API:
from maestro.trainer.models.paligemma_2.core import train
config = {"dataset": "path/to/data", "epochs": 10, ...}
train(config)
Effectiveness expectations
It saves 801 TP3T of time compared to manual configuration and is able to avoid more than 901 TP3T of common configuration errors. Experiments show that when using the default optimization parameters, the model accuracy is improved by an average of 121 TP3T compared to random parameter settings.
