Hi, I was trying to enable the python wrapper to run the unsteady fsi case on Ubuntu 18.04. There was an ERROR saying that "Python dependency not found". But it previously showed that"Program python3 found: YES (/usr/bin/python3)
". How could I fix this? Thanks in advance.

( I had several python versions(2.x, 3.5, 3.7 etc.) installed )

Here are the full screen outputs:
