ModuleNotFoundError：即使在Windows PC中使用anaconda成功安装了opencv库之后，在Spyder IDE中也没有名为“ cv2”的模块

Question

I have successfully installed opencv and dlib in my windows pc following this site: https://www.learnopencv.com/install-opencv-3-and-dlib-on-windows-python-only/ I have checked the version of opencv and dlib in cmd which make me sure that these libraries are installed in my windows pc. Version checking in CMD

Now I open spyder which was installed by anaconda as default and I imported cv2 and dlib. But it gives error as no module named cv2 found, no module named dlib found.

Which step am I missing here? I am just a starter in programming world. Thanks for your help in advance.

Answer 1

You must run Spyder in the same virtual env as you are running your Python instance, in the screenshot.

You can do that by first installing Spyder in the virtual env, like so,

1. activate opencv-env
2. conda install spyder

and then calling the spyder executable from the same console.

That should do the trick.
