Hi there
since I installed Xcode 13 b3, codes running under python 3.9.6 hang at various stages:
I have no error messages just that python resources jump to >100% of CPU.
This happens either loading a module (e.g. from astropy.modeling import models - but from astropy.constants.si import c its fine) or creating a reasonably sized array with numpy.arange().
I reinstalled Xcode 12.5.1 with its CLT and the code loads and creates what is needed.
My vague idea is that the memory resources are badly handled using Xcode 13+CLTs (ahh everything worked fine with Xcode 13 b1) with Xcode 13 I have been using: Big Sur 11.5, or Monterey 12.0b3 . so the machine seems not to be an issue. any ideas?
