合设环境,固件与驱动版本:1.0.13 CANN版本:6.0.RC1.alpha003,python3.7.5环境中运行代码时出现ModuleNotFoundError: No module named 'cv2',搜索后说是要安装opencv,可是换哪个镜像源都装不上。原先python3.6环境里的opencv被我不小心删了。请问应该如何安装opencv呢?非常感谢!本...
If you have previous/other manually installed (= not installed viapip) version of OpenCV installed (e.g. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts. Select the correct package for your environment: There are four different packages and ...
pip install --no-binary :all: opencv-python If you need contrib modules or headless version, just change the package name (step 4 in the previous section is not needed). However, any additional CMake flags can be provided via environment variables as described in step 3 of the manual buil...

解决方法: 加上–ignore-installed的命令: sudo -H pip install --ignore-installed opencv-python pip3 install --user -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python 我这样写的,终于解决了
( source /path/to/the/venv/bin/activate, see the suggested command in the error output) If you just open terminal and run installation command, the package will be installed to the system interpreter ( " which python" will show the path to the interpreter). You may use that sys...
Your installed version is: 2.27 官方推荐的办法是 https:///pytorch/vision/issues/3207 pip install opencv-contrib-python 发现如果用 conda install -c conda-forge opencv 会有一大堆不兼容。 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.

问无法使用python 3.8构建opencv-pythonENSobel算子是一个主要用于边缘检测的离散微分算子（discrete differentiation operator）。它结合了高斯平滑和微分求导，用来计算图像灰度函数的近似梯度。在图像的任意一点使用此算子，都将会产生对应的梯度矢量或是其法矢量。
