Hi, It seems your depth_map value is None. You can check how you load the depth_map and find out why it fails to load a file.

I'm so sorry,Could you please let me know at which stage the depth_map is typically obtained? I'm not quite sure how to acquire it. Thank you very much!

You can set a breakpoint here to check whether this path is valid.

I met the same issue, do you solve it?

通过在 load_scannet_mv_data.py 中添加 print，我发现我的问题出现在 2D/scene_0000_01/depth/5120.png 这个文件损坏了。你可以通过在代码中添加调试语句，来查看自己出问题的图像位置。

By adding print in load_scannet_mv_data.py, I found that my issue was caused by a corrupted file: 2D/scene_0000_01/depth/5120.png. You can add debugging statements in the code to locate the problematic image in your case.
