PyCharm setup for rmf_core

[albertleng]

I am developing a fleet adapter based on rmf_core in PyCharm. I want to have autocomplete etc. to ease my development. I followed steps in PyCharm import external library and IDEs and managed to setup the environment for ROS/ROS2. I also added the path to rmf_core into Interpreter Paths as shown in picture below.

However, I still get the warning red curvy lines for FleetState, RobotState etc as shown below.

Any idea how to resolve that? Thanks.

I think you'll want to seek advice from pybind11 which is the tool used to create the python bindings.

But also please note that the python bindings are provided in the rmf_fleet_adapter_python repository, not in rmf_core. I think you'll want to build rmf_fleet_adapter_python and then source the python library that gets produced from building that package.

Thanks @mxgrey for your answer.

I think my issue is not related to python binding per se. After adding the path (as shown in the screenshot) to interpreter paths, the red curvy lines for FleetState, RobotState etc. go away.

On a sidenote, I wanted to tinker with rmf_fleet_adapter_python. Following the instructions in rmf_fleet_adapter_python repository, building rmf_fleet_adapter_python via colcon build --packages-select rmf_fleet_adapter_python gave me the following errors:

I have sourced the workspace. There are no tabs for discussions and issues in rmf_fleet_adapter_python repository. Hence, I am seeking for help here.

There are no tabs for discussions and issues in rmf_fleet_adapter_python repository. Hence, I am seeking for help here.

Thanks for pointing that out; that was an oversight. Those tabs should be activated now. I've activated the Issues tab for that repo, but we can continue using the discussion board of this repo for all matters related to RMF.

gave me the following errors:

This is a known issue in the Foxy distribution which should have been fixed in a recent sync. If you haven't updated your foxy distro in a few weeks, then I recommend trying:

$ sudo apt update
$ sudo apt dist-upgrade

If that still fails for some reason, then a sure-fire way to fix that error is to clone the FastRTPS repo into your workspace.
