Hello, I'm reproducing your code. Could you please provide the corresponding code for the visualization process? Thank you.

@pgw111 May I ask if you have successfully reproduced the code and if it is convenient to provide the dataset you have processed
I encountered the following issue with the dataset when reproducing：

### FileNotFoundError: [Errno 2] No such file or directory: '/root/autodl-tmp/data/3dmatch/sun3d-brown_cs_3-brown_cs3/seq-01/frame-000020.complete.png'

It seems that some data was not processed when using the Python file of process3dmatch to process the dataset

@0xzcy I have successfully reproduced the code using the ScanNet dataset, haven't tried it with the 3DMatch dataset yet, you might want to try using the ScanNet dataset?
