Installed opencv using:

Package plan for installation in environment /Users/mona/anaconda:

The following NEW packages will be INSTALLED:

    libgfortran: 3.0.0-1       anaconda   
    openblas:    0.2.19-1      anaconda   

The following packages will be SUPERSEDED by a higher-priority channel:

    conda:       4.3.22-py36_0 conda-forge --> 4.3.22-py36_0 anaconda
    conda-env:   2.6.0-0       conda-forge --> 2.6.0-0       anaconda

But still the same error. Here's the output of my conda list https://pastebin.com/gP0F0Qnz How should I fix it so that I can import cv2 ?

Mona

it seems that you do not have openblas installed, which is a required module of opencv, but somehow is not included in its dependencies so you have to install it manually, you may confirm this with conda list|grep openblas

If you do not have openblas, install it using following command: conda install -c conda-forge openblas=0.2.19

Hope that helps
