Thanks for the information!

I found numpy aliases are marked deprecated in 1.20.0: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
and actually removed in 1.24.0: https://numpy.org/devdocs/release/1.24.0-notes.html#expired-deprecations

• Quickest solution: downgrade to numpy1.23.5
• Follow up solution: disgard usage of numpy alias, use python builtin types and str-compare data.dtype == "bool" instead
