DLL load failed error when importing cv2

I have installed opencv on my windows machine using python 3.6 without any issues, using:

pip install opencv-python

but when I try to import cv2 I get the following error

ImportError: DLL load failed: The specified module could not be found.

I have seen this post

It says cv2 doesn't work with python 3 I was wondering if this has been fixed or if there is a way around it

Solution

  • You can download the latest OpenCV 3.2.0 for Python 3.6 on Windows 32-bit or 64-bit machine, look for file starts withopencv_python‑3.2.0‑cp36‑cp36m, from this unofficial site. Then type below command to install it:

    • pip install opencv_python‑3.2.0‑cp36‑cp36m‑win32.whl (32-bit version)
    • pip install opencv_python‑3.2.0‑cp36‑cp36m‑win_amd64.whl (64-bit version)

    I think it would be easier.
