FileNotFoundError: VisDroneDataset: [Errno 2] No such file or directory: 'Offshore-platform'

[QMLmulan]

作者您好，我想请问一下，我在"D:\xxx\YOLC-main\configs\yolc.py"中，classes = ("Offshore-platform")替换了自己的类，还是出现这样 FileNotFoundError: VisDroneDataset: [Errno 2] No such file or directory: 'Offshore-platform'，请问还有哪里需要再修改？D:\xxx\YOLC-main\VisDrone_Dataset.py里的CLASSES = (‘’Offshore-platform，'bicycle', 'car', 'motorcycle', 'airplane', 'bus',~)我也对应加了，不知道还有哪里需要修改，求助求助

可以贴一下完整的报错吗，以及配置文件

从报错看不出来问题在哪。可以先检查下config里的文件路径是否正确，只改classes和文件路径应该没问题
