Question: I installed numpy 2.0.0  pip install numpy==2.0.0 import numpy as np np.__version__ #2.0.0  then I installed: pip install opencv-python Requirement already satisfied: opencv-python in /usr/local/lib/python3.10/dist-packages (4.8.0.76) Requirement already satisfied: numpy>=1.21.2 in /usr/local/lib/python3.10/dist-packages (from opencv-python) (2.0.0)  Then I did: import cv2  I am getting this error:  A module that was compiled using NumPy 1.x cannot be run in NumPy 2.0.0 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.

Answer: There are two solutions for this error: 1. downgrade your numpy to 1.26.4 pip install numpy==1.26.4  or pip install "numpy<2.0"  Make sure to restart your kernel after downgrading numpy   Another option is: 2. install the latest version of the module which is failing* I had an old version of opencv-python 4.8.0.76 I was able to get this working by installing the latest version of opencv-python by pip install opencv-python==4.10.0.84  *Some modules may still not work with numpy 2.0  'We expect that some modules will need time to support NumPy 2'
