May choose the function os.path.splitext ?

[Z-MiCTrue]

In line 89 of the file /utils/datasets.py, there is a statement: label_path = img_path.split(".")[0] + ".txt" which may cause some errors, such as using the format of './xxx/xxx. txt '.
To avoid such errors, label_path = os.path.splitext(img_path)[0] + ".txt" might be better?

linux和windows系统路径格式不同，估计得用pathlib更好
