31.10.2021 · ImportError: numpy.core.multiarray failed to import in cv2 / matplotlib / pyinstaller / pytorch. Let’s try to understand this. Most machine learning and deep learning python libraries like cv2, matplotlib, pyinstaller, PyTorch, etc. Uses numpy for several operations they perform. More often, we need more than one of them to build our program.

I am currently studying Pytorch and trying to use the cv2 module. I am using Jupyter notebook and Windows. I have installed opencv like this: !pip install opencv-python When I choose the kernel (by change kernel option) Python3 and import cv2 then there is no problem. But when I choose the kernel Pytorch and import cv2, then there is an error:
