python3-numba: AttributeError: module 'numpy' has no attribute 'long'

Reported by: jakimowb Owned by: osgeo4w-dev@…
Priority: normal Component: Package
Version: Keywords: numba python numpy
Cc: jakimowb


By now, the latest versions of numba and numpy available in the OSGeo4W installer are: numba 0.51.2-2 (python3-numba) and numpy 1.24.1-1 (python3-nunmpy

numba 0.51 uses np.long (e.g. in numba/core(types/ ), but this was removed from numpy with version 1.24. This leads to the following python import error:

Python 3.9.18 (heads/master:5eba59e, Feb  1 2024, 20:02:10) [MSC v.1929 64 bit (AMD64)] on win32

>>> import numba
F:\OSGeo4W\apps\Python39\lib\site-packages\numba\core\types\ FutureWarning: In the future `np.long` will be defined as the corresponding NumPy scalar.  (This may have returned Python scalars in past versions.
  long_ = _make_signed(np.long)
Traceback (most recent call last):

    from numba.core import types, errors
  File "F:\OSGeo4W\apps\Python39\lib\site-packages\numba\core\types\", line 108, in <module>
    long_ = _make_signed(np.long)

    raise AttributeError("module {!r} has no attribute "
AttributeError: module 'numpy' has no attribute 'long'

I recommend to update numba to a more recent version, e.g. 0.53.1
