The release is corrupted about tessdata HOT 9 CLOSED

I can confirm that problem. The release zip files are provided by GitHub, so there is nothing we can do to fix it. But the tar.gz file is fine, so there is a working alternative.

from tessdata.

tessdata repository is huge repository and:

ZIP format had a 4 GB limit on various things (uncompressed size of a file, compressed size of a file, and total size of the archive), as well as a limit of 65,535 entries in a ZIP archive.

so it seems you chose to use the wrong technology. Use git clone --depth 1 https://github.com/tesseract-ocr/tessdata.git for downloading all data.

The tar.gz file is about 565 MiB. The zip file 543 MiB, far away from the limit but the size seems to be too small.

git clone is a good alternative which has several advantages compared to downloading a zip or tar.gz file.

I am also seeing the same issue with 4.0.0. I opened an issue earlier, but don't see it now.

Is the root problem understood? I don't think the zip file we have been downloading has been updated in some time.

Our build system does this quite often, so the issue has come up very recently, within the last few days.

Also, we had similar issues with the tar.gz file.

Thanks,

Is the root problem understood?

Ask Microsoft, the owners of GitHub. The zip files are created automatically by GitHub.

Also, we had similar issues with the tar.gz file.

In my test tar.gz worked fine.

I now tried several downloads of the zip file using wget. The resulting files had different sizes although there was no download error. All downloads finished after 1:40, so maybe the GitHub servers have a fixed time limit.

More tests confirmed that the download terminates after exactly 100 seconds, resulting in a partial file.

I close this issue as we cannot solve it, but there is a good alternative way to get the data using git clone (see above).

Hi !

Thank you for your reply. I will use git clone instead. About tar.gz in my remember it did not work either but i'm not sure.

Anyway, the main thing is that I can use tessdata somehow !

thank you for your explanations and your time :)
