Remove Hardcoded Paths in Config and Test Files

[ArrKss]

Description

The project contains hardcoded file paths in both the configuration file (diffusion/configs/config_relactrl_pixart_1024.py) and test script (pipeline/test_relactrl_pixart_1024.py). These paths reference specific user directories (e.g., /home/jovyan/maao-data-cephfs-0/...) which will not work for other users running the code.

Examples

In pipeline/test_relactrl_pixart_1024.py:

t5_model_path = "/home/jovyan/maao-data-cephfs-0/dataspace/maao/projects/Common/models/PixArt-alpha/"

In diffusion/configs/config_relactrl_pixart_1024.py:

model_path = '/home/jovyan/maao-data-cephfs-0/dataspace/maao/projects/Common/models/PixArt-alpha/PixArt-ControlNet/PixArt-XL-2-1024-ControlNet.pth'

Proposed Solution

Replace hardcoded paths with environment variables or relative paths. Consider:

1. Using environment variables for model paths: os.environ.get('PIXART_MODEL_PATH')
2. Supporting path configuration through command-line arguments with reasonable defaults
3. Creating a standardized model directory structure that's relative to the project root
