@supra56 , do you know how can fix my issue? Thanks.

I ensured that the Python3 library in Cmake is using '/home/user/anaconda3/lib/libpython3.7m.so' .

Sorry, I was building and installing OpenCV 4.1. I think I have partially fixed my problem by upgrading my Ubuntu's Pyth

According to your instruction, I have made the upgrade, then I corrected my Cmake config, and clean the build and rebuil

@supra56, I installed anaconda3 and its python 3.7 and uploaded my Cmake config's pic.

I have updated the progress. Please help.

I didn't change the ImportError message. The ".format(fnames))" is missing from the warning.

I downloaded the required files from https://github.com/opencv/opencv_3rdparty/tree/contrib_xfeatures2d_boostdesc_201610

Thank you. It works!!

I am trying to create a depth map from stereo images, but the generated depth map is only black in color. Could you suggest what should I improve for getting a decent depth map? Thanks.

In my view, the parameters using in the constructor bpm is wrong. How to correct them?
