Good catch... again.

Sadly this script takes too many resources to run in GH CI. I tried in

https://github.com/janosh/matbench-discovery/blob/1db982a01a8518c5e16038d1893bc0b2840fccac/.github/workflows/test-scripts.yml#L17-L18

but the jobs were killed. Probably due to high mem use. So thanks for continually testing this. Hopefully it works now! 🤞
