Good catch... again.

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

matbench-discovery/.github/workflows/test-scripts.yml

Lines 17 to 18 in 1db982a

	- scripts/compile_metrics.py
	- scripts/analyze_element_errors.py

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