zipfile.BadZipFile: Truncated file header

[Hiusam]

Hi, I ran

python contrib/99991/download.py -c .tonemap.jpg -d /home/datasets/hypersim --silent

and it raise:

Traceback (most recent call last):
  File "contrib/99991/download.py", line 620, in <module>
    main()
  File "contrib/99991/download.py", line 616, in main

I encountered this error after finishing downloading hypersim/ai_011_009/images/scene_cam_00_final_preview/frame.0066.tonemap.jpg

And advice? Thank you.

I just ran this:

python download.py --contains ai_011_009/images/scene_cam_00_final_preview/frame.0066.tonemap.jpg --scene ai_011_009

And it worked for me. I didn't get the same error as you. Were you able to download other files successfully?

Hi, I ran the command for several times and found the error raised when downloading different files.

• Have you been able to download any files successfully using the user-contributed partial download script? (You already said that the script fails for several files, but does it succeed for any files?)
• What if you don't use any --contains filters? Can you download a single scene successfully, e.g., by using --scene ai_001_001 in your command-line invocation?
• What happens when you paste https://docs-assets.developer.apple.com/ml-research/datasets/hypersim/v1/scenes/ai_001_001.zip into a browser? Can you download the entire thing successfully? Can you decompress it successfully?

Simply after running the script several times, I make it download all the files. Thank you for your patience.
