anaconda ImportError: DLL load failed while importing cv2: The specified module could not be found
问题
我正在尝试在我的笔记本电脑上安装OpenCV，但一直出现ImportError: DLL load failed while importing cv2: The specified module could not be found.的错误。我尝试在Anaconda环境中使用conda install -c conda-forge opencv进行安装，但结果也是一样的，如果我使用普通的Python 3.10解释器，使用opencv-python和opencv-contrib-python也会得到相同的结果。我还尝试自己编译模块，但cv2.cp310-win_amd64也会出现相同的错误...
是否有预构建的二进制文件可以使用？或者我应该寻找不同的机器学习模块？
昨天我回家后尝试在我的个人电脑上安装opencv-python，它立即起作用。我的个人电脑上有GTX 1070，而我工作笔记本上有RTX A1000，我需要在工作笔记本上安装OpenCV。所以我认为可能不支持CUDA核心。我找到了这个教程https://machinelearningprojects.net/build-opencv-with-cuda-and-cudnn/，但在安装Nvidia SDK、cudnn并从源代码编译OpenCV后，我仍然遇到相同的错误。即使将OpenCV的输出文件夹和CUDA SDK的bin文件夹附加到Python的dll_path中也没有解决问题。
像这里建议的禁用BUILD_SHARED_LIBS也没有效果...https://forum.opencv.org/t/opencv-w-cuda-build-seems-successful-but-import-cv2-fails/11328/3

I am trying to install opencv on my laptop but I keep getting ImportError: DLL load failed while importing cv2: The specified module could not be found.
I tried installing installing with conda install -c conda-forge opencv in an anaconda env.
But I also get the same result if I use my normal python 3.10 interpreter with opencv-python and opencv-contrib-python.
I also tried to compile the module myself but cv2.cp310-win_amd64 gives me the same error as well...
Isnt there just an prebuild binary I can use? or should I look for an different ML module?
Yesterday when I came home I tried installing opencv-python on my personal computer. And it worked instantly. I have an GTX 1070 in that pc and an RTX A1000 in the work laptop I need opencv on. So I tought that the cuda cores might not be supported or something.
I found this tutorial https://machinelearningprojects.net/build-opencv-with-cuda-and-cudnn/
But after installing the Nvidia SDK, cudnn and compiling opencv from source I still get the same error.
Even with appending the opencv output folder and the cuda sdk bin folder to python's dll_path.
Disabling BUILD_SHARED_LIBS as suggested in here also does nothing....

这发生在我身上就在今早，我通过使用pip安装opencv来修复它。首先，我移除了conda的opencv安装。在安装了opencv的环境中执行以下命令：
conda remove opencv
一旦移除了，执行以下命令：
pip install opencv-python
希望对你有帮助。
英文:
This happened to me just this morning, and I fixed it by installing opencv using pip. First, I removed conda's opencv installation. In the environment where it is installed type
conda remove opencv
Once it is removed, type
pip install opencv-python
Hope it helps

使用Python 3.6与conda install -c conda-forge opencv=3.2.0，如此处所述：https://stackoverflow.com/questions/44668602/opencv-python-importerror-dll-load-failed-the-specified-module-could-not-be-fo?rq=1 已解决了我笔记本上的RTX A1000的问题。奇怪的是，opencv在我的桌面上与GTX 1070的Python 3.10一起工作。

Weird opencv works with python 3.10 on my desktop with an GTX 1070
