when i trained using 3dmatch , the dataloader have one problem

[WuHaoYu21]

in main.py line 99 ,'cofig.train_loader, neighborhood_limits = get_dataloader(train_set,config,shuffle=True)'
this line have one problem.
the 'train_set' need one file '3dmatch/3dmatch/train/rgbd-scenes-v2-scene_01/cloud_bin_1.pth' , but i can't find the ''cloud_bin_1.pth''.
i have already download 3dmatch.zip ,and unzip this file.
but in the unzip file,i don't find the ''cloud_bin_1.pth''.
i hope you can help me.
thank you very much.

I have encountered the same problem.

This is the error log:

[WuHaoYu21]

yes.
Maybe the dataset:3dmatch.zip has been already changed?
So, we can't find the ****.pth ?
i don't know.

i know how to solve this problem.
The dataset , you need to download from https://github.com/overlappredator/OverlapPredator

Hi, I have some questions about Lepard debugging. dataset/dataloader.py line 5 I can't find the file for cpp_wrappers.cpp_neighbors. Radius_neighbors Can we add QQ friends to chat each other QQ number: 844787024

cd cpp_wrappers
sh compile_wrappers.sh
cd ..

[WuHaoYu21]

i can't find your qq number

[ChaunceyQin]

I also have the same problem, may I ask how to solve it at last？？？

I still have the same problem after downloading it，I don't know how to solve it.

I also upload the correct 3DMatch to google drive. Have a try.
