> 你好,我想用semantic-kitti数据集中的测试集进行推理可视化,之前用mayavi成功做过验证集的推理可视化,但是可视化测试集时出现问题,报错说没有预处理的.npy文件,但是.npy文件是处理.label和.invalid文件得到的,所以想问一下推理可视化一定需要.label和.invalid文件吗? you should modify the generate_output.py according to the note. `data_loader = data_module.val_dataloader() # data_loader = data_module.test_dataloader() # use this if you want to infer on test set`

> I checked the path to my dataset,And there is nothing wrong,But I don't know why the dataset doesn't load.Can you give me some tips? ok,兄弟,我找到方法了,是数据集的问题,这个代码需要带normal后缀的数据集,我们一开始选错了数据集。 ![Image](https://github.com/user-attachments/assets/1bed52d0-ca27-44df-806f-948558a16782)
