重现步骤

下载repo
配置项目依赖
开启webui
按训练→Step 2a→处理数据

ModuleNotFoundError: No module named 'infer'

Commit: 8f2fdbf483 Commit: 81eed5e8f6

运行环境：
阿里云ecs.gn6i-c4g1.xlarge NVIDIA Telsa T4 GPU实例
OS: Ubuntu 24.04
Python: Python3.12.3
CUDA: 11.8

在Step 2a步骤执行数据处理时程序出现意外退出

WebUI Log:

【Data slicing】

在项目根目录下logs/your-experiment-name/目录内生成了一个preprocess.log文件，但未写入任何内容

补充：

经测试，在Windows平台下该问题也存在，按照README.md指导，使用python webui.py命令启动WebUI执行Step 2a步骤时也会出现ModuleNotFoundError: No module named 'infer'

在WSL2 Ubuntu 24.04 使用CPU推理版本python webui.py命令启动WebUI执行Step 2a步骤故障同样存在

总而言之故障现象与上述内容完全一致

OS:
Windows Insider Preview Build 29680.1000.rs_prerelease.260925-1447
Ubuntu 24.04

Python:
Python 3.12.3

CDUA:
NO GPU

*所有部署操作严格按照README.md指导执行，在此基础上产生上述故障
