Cannot import tf_conversions
Ubuntu 18.04, ros melodic, Python 2.7
I tried to import tf_conversions, but got the following error:
import tf_conversions
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/ros/melodic/lib/python2.7/dist-packages/tf_conversions/__init__.py", line 30, in <module>

from PyKDL import *
ImportError: No module named sip
I tried to build orocos-kdl with python-orocos-kdl from source, but building only succeeds when ros-orocos-kdl isn't installed.
