subprocess.CalledProcessError: Command '['tar', '-I', 'zstd', '-xf', 'data/past_failures_label.lmdb.tar.zst']' returned non-zero exit status 1.

Steps to reproduce:

• Remove the data directory
• Run scripts/commit_classifier.py

The tar command works when dropping the -I zstd part.

Hey @suhaibmujahid , for some reason. I cannot reproduce the error. On my side, the data folder is downloaded without any errors coming up.

[suhaibmujahid]

I can reproduce it on macOS, example:

$ tar --version
bsdtar 3.5.3 - libarchive 3.5.3 zlib/1.2.11 liblzma/5.0.5 bz2lib/1.0.8

$ tar -I zstd -xf ./data/commit_experiences.lmdb.tar.zst
tar: Error inclusion pattern: Error reading 'zstd'

There is no error if I strip -I zstd, example:

$ tar -xf ./data/commit_experiences.lmdb.tar.zst

Also, there is no error if I use the GNU version of tar, example:

$ brew install gnu-tar
...

$ gtar --version

$ gtar -I zstd -xf ./data/commit_experiences.lmdb.tar.zst

@suhaibmujahid I am unable to move past this error. This is the error I am getting currently. Kindly assist

nafeesah@DESKTOP-1N5TMF8:~/bugbug$ tar -xf ./data/commit_experiences.lmdb.tar.zst
tar: ./data/commit_experiences.lmdb.tar.zst: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now

It seems that you do not have the ./data/commit_experiences.lmdb.tar.zst file installed. It will be installed when you run the scripts/commit_classifier.py script.

Resolving #3755 will help to mitigate the problem, but will not solve it.
