I have pcl 1.8.1 on ubuntu 18.04, and python-pcl version is 0.3.0a1. I'm using Pycharm, but it throws this error on the first line of import pcl:
libpcl_keypoints.so.1.7: cannot open shared object file: No such file or directory

I can find libpcl_keypoints.so.1.8 file here: /usr/lib/x86_64-linux-gnu/libpcl_keypoints.so.1.8.1, but somehow the binding is not linked to 1.8 version, which I don't know why. I ran ldconfig and restart but it didn't help. Any idea?
Thanks.
