So many questions already about this topic, but I didn\'t find any satisfying answer about the \"DLL not found\" traditional issue.
Regarding the comment in the question, always remove any existing opencv
package before installing another one because, opencv
from unofficial and official sites will be considered as 2 packages by pip
.
You can install official opencv
if you follow my answer here. You get that error because of a problem with Anaconda
.
But if you install official opencv
it will autocomplete and give suggestions in your python IDE (see this). So, if you need autocomplete as well, you need to go with unofficial opencv.
