Indexing not working

[daelba]

I have similar issue to #41. meta-data.json is not created.

Ubuntu 24.04.1 LTS

pip show qlever:

Where Q31519.ttl was downloaded from https://www.wikidata.org/wiki/Special:EntityData/Q31519.ttl. It is small file with few triples, so there can't be any memory issue.

Is there any problem in the Qleverfile, or is it qlever bug? Thanks.

@daelba Sorry for the late reply. That was a bug introduced by a recent commit. Fixed now by 466df71 . Please reinstall using pip install --upgrade qlever or git pull if you have have cloned https://github.com/ad-freiburg/qlever-control

[daelba]

Thanks for your reply. Now I have:

$ pip show qlever

But the result is still the same.

Hello, I continue on this issue while I have a similar problem. It occurs only on one specific computers. I compare here the behavior between two systems with similar OS.

$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.1 LTS"

On both systems. 32BG ram on both systems. 8 cores on both systems. The main difference is they are both virtualised with different backend.

$ qlever --version
qlever 0.5.12

On both systems. Result is the same on both systems for qlever setup-config olympics and qlever get-data. When it comes to index, I have on the first (not working)

$ qlever index
