[SOLVED] NRP from source installation. cle-start Problems

#1

Dear Human Brain Project community,

I am new to the Neurorobotics Platform and would like
to use it for some SpiNNaker + eDVS simulations.

I did a from source installation on Ubuntu 16.04 LTS.

If I try to run cle-start, I get the error message below.
I would guess that the Error [rospack] Error: package ‘rosbridge_server’ not found
might be the main problem. I read all the cle-start ERROR entries in this blog but
I am not shure what is the problem and I don’t know how to fix this.

Of course, I set the .bashrc PYTHONPATH="".

Thank you very much and best regards,
Thorben Schoepe

Does anybody have an idea what’s exactly the problem?

Hi,

I think you might be setting the PYTHONPATH after the NRP loads the required variables. In your .bashrc you should have something like this:

export HBP=$HOME/Documents/NRP # Or whatever installation path you chose
export NRP=$HOME/Documents/NRP
export PYTHONPATH=
. $HBP/user-scripts/nrp_variables
. $HBP/user-scripts/nrp_aliases

If the PYTHONPATH is set afterwards then it would be empty. You can confirm that by running

echo $PYTHONPATH

on your terminal after running

source ~/.bashrc

If there is no output then the problem should be as I described. Else we can investigate further.

Regards,
Manos

Hi,

The order in my .bashrc is the following one:

export PYTHONPATH=
export HBP=/home/nbsroot/Documents/NRP # Or whatever installation path you chose
export NRP_INSTALL_MODE=user # this has to be set to ‘user’, else the cloning and builds will fail
. $HBP/user-scripts/nrp_variables
. $HBP/user-scripts/nrp_aliases

source ~/.bashrc
echo $PYTHONPATH returns me:

/opt/ros/kinetic/lib/python2.7/dist-packages:/home/nbsroot/Documents/NRP/retina/build/lib:/home/nbsroot/.local/lib/python2.7/site-packages:/home/nbsroot/.local/lib/x86_64-linux-gnu/python2.7/site-packages:/home/nbsroot/Documents/NRP/GazeboRosPackages/devel/lib/python2.7/dist-packages:/home/nbsroot/Documents/NRP/CLE/hbp_nrp_cle:/home/nbsroot/Documents/NRP/ExperimentControl/hbp_nrp_excontrol:/home/nbsroot/Documents/NRP/ExperimentControl/hbp_nrp_scxml:/home/nbsroot/Documents/NRP/ExDBackend/hbp_nrp_backend:/home/nbsroot/Documents/NRP/ExDBackend/hbp_nrp_cleserver:/home/nbsroot/Documents/NRP/ExDBackend/hbp_nrp_commons:/home/nbsroot/Documents/NRP/ExDBackend/hbp_nrp_watchdog:/home/nbsroot/Documents/NRP/ExDBackend/hbp-flask-restful-swagger-master:/home/nbsroot/Documents/NRP/VirtualCoach/hbp_nrp_virtual_coach:/home/nbsroot/Documents/NRP/BrainSimulation/hbp_nrp_music_xml:/home/nbsroot/Documents/NRP/BrainSimulation/hbp_nrp_music_interface:/home/nbsroot/Documents/NRP/BrainSimulation/hbp_nrp_distributed_nest

So it seems to be another problem.
Thanks and best regards,

Thorben

#5

Are there any further ideas?

#6

There seems to be a problem in your GazeboRosPackages. Did the build there run flawlessly?
You can cd $HBP/GazeboRosPackages and run catkin_make to retry.

Rerun configure_nrp afterwoods from user-scripts

Axel

#7

There are no errors, if I retry with catkin_make.
When I run configure_nrp, it tells me that the Storage data base
already exists. My running mode is set to full local (2).
Is that all correct?

Best regards,
Thorben

#8

Hi,

Let’s try to check the following things.

  1. Does rospack find rosbridge_server return anything? For me it is in /home/manos/Documents/NRP/GazeboRosPackages/src/rosbridge_suite-develop/rosbridge_server
  2. Is there a file called _SetVisualProperties.py in $HBP/GazeboRosPackages/devel/lib/python2.7/dist-packages/gazebo_msgs/srv/_SetVisualProperties.py ?
  3. Open a python interpreter on your console by typing python and then type try to import the package that cannot be found by typing
    from gazebo_msgs.srv import SetVisualProperties, SetLightProperties, GetLightProperties

If all these steps work then it is another problem, else something went wrong during the installation of either ros or GazeboRosPackages.

Regards,
Manos

#9

Hey,

  1. returns me: Error: package ‘rosbridge_server’ not found
    But if I check the folders manually the package ‘rosbridge_server’ is given.
    It seems to be a pass setting problem.

  2. There is a file.

  3. returns me: from: can’t read /var/mail/gazebo_msgs.srv

So, you are right. There must be an issue with the ROS or GazeboRosPackages installation
or with teh path in the .bashrc.

Best regards,
Thorben

#10

If I try to deinstall Gazebo6 by…

sudo apt-get remove --purge gazebo6* ros-kinetic-gazebo6-msgs ros-kinetic-gazebo6-plugins ros-kinetic-gazebo6-ros ros-kinetic-gazebo6-ros-control ros-kinetic-gazebo6-ros-pkgs

…it tells me that none of these packages are installed until now.

$GAZEBO_MODEL_PATH and $CMAKE_PREFIX_PATH return me a directory but the directory doesn’t exist:

nbsroot@kenyon:~$ $CMAKE_PREFIX_PATH
bash: /opt/ros/kinetic:/home/nbsroot/.local/lib/x86_64-linux-gnu/cmake/gazebo/: No such file or directory
nbsroot@kenyon:~$ $GAZEBO_MODEL_PATH
bash: /tmp/nrp-simulation-dir:/tmp/nrp-simulation-dir/assets:/home/nbsroot/.gazebo/models:/home/nbsroot/.local/share/gazebo-7/models:: No such file or directory
nbsroot@kenyon:~$

#11

Hi Thorben,

The messages that you get are normal, executing the command

nbsroot@kenyon:~$ $CMAKE_PREFIX_PATH

tries to execute the contents of the $CMAKE_PREFIX_PATH in a bash, the equivalent of doing

nbsroot@kenyon:~$ /opt/ros/kinetic:/home/nbsroot/.local/lib/x86_64-linux-gnu/cmake/gazebo/:

which resutls in an error since trying to execute a path is not a valid bash command. What you could try is to see if these paths actually exist by doing

cd  /opt/ros/kinetic

cd  /home/nbsroot/.local/lib/x86_64-linux-gnu/cmake/gazebo

One error which I can see is that your $CMAKE_PREFIX_PATH variable does not start with $HBP/GazeboRosPackages/devel . I am not sure where this variable is set, but you can try to hardcode it in your ~/.bashrc. Just add the following line at the end of the file

export CMAKE_PREFIX_PATH=$HBP/GazeboRosPackages/devel:/opt/ros/kinetic:$HOME/.local/lib/x86_64-linux-gnu/cmake/gazebo/

, and

source ~/.bashrc

Then go to $HBP/GazeboRosPackages

rm -rf devel/ build/

and

catkin_make

Let’s see if that fixes the problem, else it might be coming from somewhere else.

Regards,
Manos

#12

One last check, can you

echo $ROS_PACKAGE_PATH

and send me the output?

Regards,
Manos

#13

/home/nbsroot/.local/lib/x86_64-linux-gnu does not exist but cmake and gazebo-7 are directly in /home/nbsroot/.local/lib/.

#14

echo $ROS_PACKAGE_PATH

returns me:

/opt/ros/kinetic/share

#15

The errors are still all the same.

#16

Hi,

Can you try to add the following line to the end of your ~/.bashrc?

export ROS_PACKAGE_PATH=$HBP/GazeboRosPackages/src:/opt/ros/kinetic/share

source it, and then try running the cle-start again? Apparently something goes wrong when setting the environment variables.

Regards,
Manos

#17

If this path is the ERROR, I think I eventually found the problem.

Earlier in the installation the Error : catkin_make: command not found, appeared.
Because of that I added the line source /opt/ros/kinetic/setup.bash to the .bashrc,
which I found somewhere in the internet.
If I remove the line I don’t get the Errors anymore.

Best regards,
Thorben

#18

I am able to run the examples now.
Thank you very much for your help!!!

Hi Thorben,

I am happy to hear that, can you change the title of the thread to [SOLVED] NRP from source installation. cle-start Problems? Thanks!
