Hello,

I attempted a vanilla installation of olympics as below but there is a complaint at the indexing saying to let the developers know, so I've pasted all in below...

Many thanks,

Gos

[gos@dx]$ qlever setup-config olympics

Command: setup-config

cat /data/intermine/local/lib/python3.11/site-packages/qlever/Qleverfiles/Qleverfile.olympics | sed -E 's/(^ACCESS_TOKEN.*)/\1_eZtfMwE6cU1n/'> Qleverfile

Created Qleverfile for config "olympics" in current directory

[gos@dx]$ qlever get-data

Command: get-data

curl -sLo olympics.zip -C - https://github.com/wallscope/olympics-rdf/raw/master/data/olympics-nt-nodup.zip && unzip -q -o olympics.zip && rm olympics.zip

Download successful, total file size: 337,695,911 bytes

[gos@dx]$ qlever index

Command: index

echo '{ "ascii-prefixes-only": false, "num-triples-per-batch": 100000 }' > olympics.settings.json

@gmicklem Sorry for the late reply. Can you please run

echo '{ "ascii-prefixes-only": false, "num-triples-per-batch": 100000 }' > olympics.settings.json
docker run --rm -u $(id -u):$(id -g) -v /etc/localtime:/etc/localtime:ro -v $(pwd):/index -w /index --init --entrypoint bash --name qlever.index.olympics docker.io/adfreiburg/qlever:latest -c 'cat olympics.nt | IndexBuilderMain -F ttl - -i olympics -s olympics.settings.json --stxxl-memory 5G | tee olympics.index-log.txt'

directly from the shell and tell me what happens then?

@gmicklem If it does not work properly with Docker, try SYSTEM = podman (edit the Qleverfile) instead

Directly from the shell the same things happens:

[gos@dx ~/intermine/qlever/olympics_test2]$ echo '{ "ascii-prefixes-only": false, "num-triples-per-batch": 100000 }' > olympics.settings.json
[gos@dx ~/intermine/qlever/olympics_test2]$ docker run --rm -u $(id -u):$(id -g) -v /etc/localtime:/etc/localtime:ro -v $(pwd):/index -w /index --init --entrypoint bash --name qlever.index.olympics docker.io/adfreiburg/qlever:latest -c 'cat olympics.nt | IndexBuilderMain -F ttl - -i olympics -s olympics.settings.json --stxxl-memory 5G | tee olympics.index-log.txt'

Thanks for your reply! Probably I should have said this is a linux system running CentOS-7 3.10.0-1160.76.1.el7.x86_64

Unfortunately podman is not installed on this system and I don't have sudo rights...
