How do I install opencv using pip?
Open anaconda command prompt and type in below command.
conda install -c conda-forge opencv

Once the 'Solving environment' is done. It will ask to download dependencies. Type 'y'.

It will install all the dependencies and then you are ready to code.
I need to install cv2 for a script that has been written for me. I tried  pip install cv2 and pip install open_cv and got the same problem - a warning message from dist.py and complains about zlib being not found. No cv2 installed. I also tried pyopenvc and pip install opencv-python.
So, I went to the opencv site and downloaded the relevant exe. Ran it - generated a heap of subdirectories and a make file and stuff. 
What do I do now?
