why same zip files don't have root dir

[JunyuanDeng]

Hello,

When I unzip the file, I found some zip files don't have the root name.

For example, DL3DV-ALL-960P/9K/4ee47d252d4bbf858085858a55f148c57dc4f178688ebeb5880e86ce6f80b0c9.zip

I use unzip -l DL3DV-ALL-960P/9K/4ee47d252d4bbf858085858a55f148c57dc4f178688ebeb5880e86ce6f80b0c9.zip to visualize, I found:

So when I unzip the file, the error would appear:

replace DL3DV-ALL-960P/9K/images_4/frame_00033.png? [y]es, [n]o, [A]ll, [N]one, [r]ename: NULL (EOF or read error, treating as "[N]one" ...)

But for most other files, it has the formate like this:

How should I do?

I meet the same problem here in 8K-9K subset, I solve this problem by checking the zip file namelist. I change the code in the download script to handle the error. Change the unzip file code at 197 lines may work for 960P download:
Change the above code

 # unzip the file 
            if rel_path.endswith('.zip'):
                zip_file = join(output_dir, rel_path)
                with zipfile.ZipFile(zip_file, 'r') as zip_ref:
                    ofile = join(output_dir, os.path.dirname(rel_path))
                    zip_ref.extractall(ofile)
                os.remove(zip_file)

into

# unzip the file 
            if rel_path.endswith('.zip'):
                zip_file = join(output_dir, rel_path)
                with zipfile.ZipFile(zip_file, 'r') as zip_ref:
                    members = zip_ref.namelist()
                    has_images_root = any(m.startswith('images') for m in members)
                    if has_images_root:
                        zip_name = os.path.basename(zip_file).split('.')[0]
                        ofile = join(output_dir, os.path.dirname(rel_path), zip_name)
                    else:
                        ofile = join(output_dir, os.path.dirname(rel_path))
                    zip_ref.extractall(ofile)
                        
                os.remove(zip_file)
