Nexus: Numpy 2.0 incompatibility #5050

Open prckent opened 3 months ago

prckent commented 3 months ago

I noticed in #5049 that the macos CI failed due to the use of Numpy 2.0 which was released on 17 June. 69 test failures. Possibly we can pin Numpy < 2.0. By eye the failures are to do with string handling and numerical precision. Needed updates might be small but backwards compatibility also needs to be considered.

@jtkrogel Can you please look and propose a reasonable way forward?

Updated the title since we have the interim workaround.
