您好可视化需要您指导一下

您好，之前复现过您的代码，现在想可视化看一下。但是它报这个错，您能帮我看看吗

python3 visualize_SemanticKITTI.py --dataset /media/wx/HDD/DQ/semantic_kitti/dataset/sequences --predictions /media/wx/HDD/DQ/RandLA-pytorch-main/result --sequence 08

我不知道我是不是哪里路径出了问题

[ksama777]

之前用的evaluate的路径是evaluate_SemanticKITTI.py --dataset /media/wx/HDD/DQ/semantic_kitti/dataset/sequences --predictions /media/wx/HDD/DQ/RandLA-pytorch-main/result --sequence 08

请问你最后可视化出来了吗？我也是这个问题，我打算可视化grid_sample后的数据集，但是也是报这个错，是要evaluate之后才会生成正确的文件吗？grid后的点云和label文件都是.npy的，但是可视化需要label是.label
