Additional information

I can train fine, but when I run the script for test.py, it reports the error FileNotFoundError: [Errno 2] No such file or directory: 'data/scannet/posed_images/scene0568_00/00000.jpg. . After checking, I found that there was no such image in that path (it seems that not all of them were converted during my first convert), so I re-ran the generate_image_scannet.py script. But it fails, with the error as described above. (Oddly enough, it works at my first run) I added the following two lines to the source code:

                try.
                    frame.load(f)
                except Exception as e.
                  print(f)

which prints the following.

<_io.BufferedReader name='scans/scene0548_00/scene0548_00.sens'>
unpack requires a buffer of 64 bytes

It seems to be a buffer shortage? I would like to know how to solve this problem. Also, since I have already converted most of the scannet data, is there any way to just specify the converted files to save time.

Thnak you for your intime help.

I have found the solution. It seems to be because there is corruption in the specified data, I re-downloaded the specified scene and this time it works. But when I execute test.py, it still doesn't go through and reports the following error:

In the grounder decoder file, change the following lines in predict function in sparse_featfusion_grounder L532-L533

to the following code

  tokens_positive = [[[[0, 1]]]
                     for _ in range(len(batch_data_samples))]
