I never encounter this bug. Can you try some other yamls？Do they reproduce the same error？

Hi, you need to download the OPV2V-H dataset, which includes the depth file.

Please unzip the `OPV2V-H-depth.zip` and `OPV2V-H-LiDAR.zip` outside of `OPV2V` folder. They will produce a parallel folder `OPV2V-H`, just as the README illustrated.

I'm very sorry about that. @xhjy2020 @Lesliewsq Please modify line 150 in `opencood/data_utils/datasets/basedataset/opv2v_basedataset.py` to ``` depth_files = self.find_camera_files(cav_path, timestamp, sensor="depth") depth_files = [depth_file.replace("OPV2V", "OPV2V_Hetero") for depth_file in depth_files] ``` There...

This is because I convert the RGB image & depth image into a hdf5 file for fast loading. In this case, I do not load the depth image from `OPV2V_Hetero`...

By the way, you can also speed up the image loading by storing all images in an HDF5 format. They are larger but facilitate your training speed. You can find...

I hope I didn't cause more trouble. I just pushed the third commit and apologize for my typo again @xhjy2020 ``` depth_files = self.find_camera_files(cav_path, timestamp, sensor="depth") depth_files = [depth_file.replace("OPV2V", "OPV2V_Hetero")...

Yes, the `shrink_header` is missing. Please check the latest commit and now it should work. @Lesliewsq

Are you using spconv 2.x? Could you provide more error information?

Hi, I think the best way is to contact the original author.
