Python 3 Libraries Not Supported

Currently, when I attempt to import python 3 libraries, I get an error (even if I add the python 3 sitepackages folder to the sys.path, I still get incompatability errors.)

Currently my workaround is to use subprocess.check_output to call my python 3 scripts, but I'd like to distribute my plugins when subprocess is not needed. Is python 3 integration a goal for this project?
