New submission from Victor Lazzarini <victor.lazzar...@nuim.ie>:
With Python 3.9.4 ctypes.CDLL does not appear to find framework libraries
installed in /Library/Frameworks.
--- With Python 3.6.5:
victor@MacBook-Pro ~ % python3
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 03:03:55)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> ctypes.CDLL('CUDA.framework/CUDA')
<CDLL 'CUDA.framework/CUDA', handle 102b044b0 at 0x102c9b9e8>
>>>
--- With Python 3.9.4
victor@MacBook-Pro ~ % python3.9
Python 3.9.4 (v3.9.4:1f2e3088f3, Apr 4 2021, 12:32:44)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> ctypes.CDLL('CUDA.framework/CUDA')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ctypes/__init__.py",
line 374, in __init__
self._handle = _dlopen(self._name, mode)
OSError: dlopen(CUDA.framework/CUDA, 6): image not found
>>>
This happens with all frameworks I have installed in /Library/Frameworks.
The full path seems to work OK:
>>> ctypes.CDLL('/Library/Frameworks/CUDA.framework/CUDA')
<CDLL '/Library/Frameworks/CUDA.framework/CUDA', handle 7fa358404180 at
0x7fa3580eeaf0>
>>>
but that's suboptimal as in MacOS you might have frameworks installed elsewhere.
