Example 1: source_frame ifco does not exist

[ninafiona]

Ubuntu 18.04, ros melodic
I tried example 1, but I get the error message source_frame ifco does not exist. (.../ec_grasp_planner/ec_grasp_planner/src/planner.py", line 184)
So, I guess this is rather a problem with the vision repo, because the ifco and object frame are not in the tf tree.
It works on my second installation, so I guess the problem is some dependency (?), I don't get an error message in my vision output though.
