在树莓派5上安装opencv的时候出现报错ImportError: numpy.core.multiarray failed to import

>>> import cv2

A module that was compiled using NumPy 1.x cannot be run in

NumPy 2.0.2 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.

ImportError: numpy.core.multiarray failed to import


 

问题原因:numpy跟opencv版本不兼容,出现错误的版本是numpy==2.0.2,opencv==4.5.2.45

解决方法:降低numpy版本。输入命令:pip install numpy==1.23.2  

成功解决
