>Description:

py37-numpy-1.19.2nb1 builds successfully on macOS, but importing it fails:

  $ python3.7 -c 'import numpy'
  python3.7(72995,0x111874dc0) malloc: can't allocate region
  :*** mach_vm_map(size=18446744071817588736, flags: 100) failed (error code=3)
  python3.7(72995,0x111874dc0) malloc: *** set a breakpoint in malloc_error_break to debug
  init_dgelsd failed init
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/Users/gson/pkg/lib/python3.7/site-packages/numpy/__init__.py", line 286, in <module>
      raise RuntimeError(msg)
  RuntimeError: Polyfit sanity test emitted a warning, most likely due to using a buggy Accelerate backend. If you compiled yourself, see site.cfg.example for information. Otherwise report this to the vendor that provided NumPy.
  RankWarning: Polyfit may be poorly conditioned
