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

[IlyaDanilenko]

I have 64-bit Python 3.7.2 from python.org installed on Windows 10 Professional 64-bit. PIP upgraded to the latest version, Both (32 and 64-bit) VS2015 C++ Redistributable exists. After PIP install opencv-contrib-python i've got folder and files for opencv 4.0.0.21 in my Python directory on disk. Seems everything is fine. But import cv2 command doesn't work. I have error: ImportError: DLL load failed: The specified module could not be found.

Check the missing dependency with https://github.com/lucasg/Dependencies

Seems there are three missing dependences.

I'm pretty sure there's some Windows package missing (hard to say if those dependencies are false positives or not).

1. Check that you do not have any conflicting cv2 installation anywhere: create a new fresh virtualenv and install opencv-python there - does the import work?
2. If the above does not help, try to install latest redistributables again: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

Also have a look at this (probably does not help as you are not using Windows Server version): https://github.com/skvark/opencv-python/pull/170/files
