VideoCapture Does Not Work in Anaconda

Question

I am using ubuntu 14.04, and have anaconda python installed. I used conda install opencv and conda install cv2 to install opencv. However I am unable to use the VideoCapture

Answer 1

I believe I had the same problem. I fixed it by adding lib folder to the PATH. For example,

export PATH="/home/iori/anaconda3/bin:$PATH"
export PATH="/home/iori/anaconda3/lib:$PATH"

My .bachrc now has this 2nd line. The first line is added by anaconda and source activate command switches this bin folder but I think it does not take care of lib folder which I found annoying because that means opencv cannot find the lib_opencv_*.so files in there and of course cv2.VideoCapture fails.

The above example will fix the problem for the default conda env. For other envs, I still need to manually add lib folder to the PATH. So, I want to know how to customize source activate command to do this automatically for me...
