I have Anaconda (version: conda 4.2.9, python3) installed and am trying to do import cv2 when I get the following error:

opencv is not compatible with python 3. I had to install opencv3 for python 3. The marked answer in how could we install opencv on anaconda? explains how to install opencv(3) for anaconda:
Run the following command:
conda install -c opencvI realized that opencv3 is also available now, run the following command:
conda install -c opencv3Edit on Aug 18, 2016: You may like to add the "menpo" channel permanently by:
conda config --add channels menpoAnd then opencv can be installed by:
conda install opencv (or opencv3)Edit on Aug 14, 2017: "clinicalgraphics" channel provides relatively newer vtk version for very recent python3
conda install -c clinicalgraphics vtkEdit on April 16, 2020 (based on @AMC's comment): OpenCV can be installed through
conda-forge(details see here)
conda install -c conda-forge opencv
You can try
conda install -c menpo opencv=3
Use this code at the Anaconda prompt:
conda update conda -c conda-canary
Then don't type this code:
conda install -c conda-forge opencv
but, instead, use:
Pip install opencv-python
It worked with me after few days of trials
See Krishna Ojha's video and read the comments below the video.
I had created my Anaconda environment and installed everything I needed, but when trying to import cv2, I always got the message "no module named cv2". I reinstalled and followed Linda's tips, which didn't work.
Finally, I noticed that my Anaconda environment didn't have cv2 installed, even with all I did.
I copied the cv2 folder to "miniconda'X'/envs/yourEnv/lib/python'X.X'/site-packages/" which worked for me.
The file may be not installed properly.
Run the following commands:
Sudo apt-get update
Sudo apt-get upgrade
then
pip install opencv-python
Check-in your jupyter notebook:
import cv2
print cv2.__version__
This may solve the issue.
If aforementioned solutions don't work for you & you have opencv installed in conda environment then try the following command:
conda install nb_conda
