NumPy 2.x와 OpenCV의 호환성 문제 A module that was compiled using NumPy 1.x cannot be run in NumPy 2.4.6AttributeError: _ARRAY_API not found: Python 3.10~3.11numpy 1.26.4opencv-python 4.8.x

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.4.6 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

OpenCV(cv2)는 NumPy 1.x 기준으로 컴파일됨
그런데 현재 환경은 NumPy 2.4.6

NumPy 2.x와 OpenCV의 호환성 문제

A module that was compiled using NumPy 1.x cannot be run in NumPy 2.4.6
AttributeError: _ARRAY_API not found

 

 

 

터미널에서 다시 버전을 맞춰주자.

제일 안정적인 버전은 아래와같다 .

Python 3.10~3.11
numpy 1.26.4
opencv-python 4.8.x

pip uninstall opencv-python
pip install opencv-python==4.8.1.78

pip install numpy==1.26.4
