Corrupted dataset file: [depth_undistorted.tar.gz], unable to extract

[YuzheHao]

I am trying to fine-tune the LightGlue model with megdaDepth dataset.
But the dataset downloaded from ETH website seems to have some missing and corrupted files:

• In scene_info.zip ---> npz files with the following ID cannot be found:

  • 0012
  • 0070
  • 0036
  • 0407

• In depth_undistorted.tar.gz ---> Cannot extract complete files from compressed tar.gz file

  • Only the files in one folder: 0065 can be extracted
  • Only can extract 500 MB h5 files from a 148 GB compressed tar.gz file
  • The extraction will stopped after 0065:

  Separate two step extraction:

  # (1) Extract with gzip first, then untar
  $ gunzip -kv depth_undistorted.tar.gz
  (after running for a while)
  gzip: depth_undistorted_backup.tar.gz: invalid compressed data--format violated

  Direct one-step extraction:

  # (1) Extract directly with tar
  $ tar -xvzf depth_undistorted.tar.gz
  depth_undistorted/
  depth_undistorted/0065/
  depth_undistorted/0065/169836871_03dcb437c5_o.h5
  .....
  depth_undistorted/0065/2700367171_f26cbce468_o.h5
  tar: Skipping to next header
  tar: Exiting with failure status due to previous errors

I tried various of extraction methods and none of them works.
I also re-downloaded the dataset files once, for avoiding the corrupted downloading problem from my side.

There is a period that this ETH dataset downloading site is down and cannot be opened, about 2 months ago, maybe something is wrong during that period?

I would appreciate it very much if you could check the data or provide a way for me to deal with this problem!
Thank you very much!
