Hey,
It seems that some of the zipfiles are corrupted.
This is what comes up when decompressing such a file:
ERRORS:
Unexpected end of archive
Has anybody solved this issue?
Posted by: asafifergan @ June 6, 2022, 10:07 a.m.Hi,
Yes this problem had been reported once before for the validation image files, however i have not been able to reproduce the issue on ubuntu 16.04, 18.04, 20.04, and windows 10 (21H1). The version installed on Ubuntu used the most recent version in the ubuntu universe repository, and were installed with '$ sudo apt install p7zip-full p7zip-rar'
Since i wasn't able to reproduce it i assumed the files must have gotten corrupted during download.
They are compressed with 7-Zip (v. 21.07) on windows 10 (21H1), do you have 7zip installed? and if such which version?
If you can let me know which files throw the error and which operating system / version of 7-zip you are using to decompress it, then maybe i can help.
Else trying to unzip it on another computer or redownloading it might solve the issue.
Hey! Thanks for your answer.
I'm working on ubuntu 20.4 and I have 7z installed.
Every zipfile besides Train.zip.001, Valid.zip.001 and the Train.zip.001 annotations zip is of binary type and not archive, and seem to contain frames that already exist in Train.zip.001 and Valid.zip.001.
In total I have managed to download about 566,000 frames.
Posted by: asafifergan @ June 7, 2022, 10:21 a.m.Yes they are binary files as they are extension of the split001 archives, each archive have been split up into several files so not one file would be larger than 1 GB.
By downloading all of the files and running '$ 7z x path/to/Valid.7z' it should automatically unzip the contents of all files. However if one is damaged it will be able to still extract some data but fail during extraction.
If i provide some checksum values for each file could you double check if yours deviate from the ones we have on the server?
