Edit 1 : I can't reopen this subject (I don't have enough point for) , but it seems that there is an issues in python, try to read the comment, Thank you

It doesn't work I still have the same error

Moda ( 2014-07-07 06:11:06 -0500 )edit

did you do rosdep install <package name=""> ? and then roscd takes you to the package..?

sai ( 2014-07-07 06:19:01 -0500 )edit

roscd takes me to another folder : devel So what is the issue?

Moda ( 2014-07-07 06:45:26 -0500 )edit

roscd <package name=""> should take you to the package you are using

So what can I do? I have just deleted everythink and redo the tutorials but I still have the same error

I tried on my PC running ubuntu 12.04 and fuerte, rosrun diagnostic_aggregator anlyzer_loader runs some program and that means that the executable exists for me. I am not sure what is causing you the problem that the `executable does not exist`

I am using groovy, does it change anythink?

I suspect you don't have the diagnostic_aggregator package installed.

If you've using ROS Groovy on Ubuntu, you can install it by running:

sudo apt-get install ros-groovy-diagnostic-aggregator

EDIT

This is a bug in the diagnostics package; I've filed it here: https://github.com/ros/diagnostics/is...

Until it's fixed, you should be able to complete the tutorial by checking the diagnostics package out from source and adding it to your catkin workspace.

Sorry but I don't understand what I have to do. can you be more specific please? Thank you

In the src folder of your catkin workspace, do

git clone https://github.com/ros/diagnostics.git

and then rebuild your workspace.

It works!!!! Thank you very much!

Moda ( 2014-07-10 03:31:01 -0500 )edit

it doesn't work for me. Roscd diagnostic_updater takes me to a directory under install isolated which doesn't have python libraries in it. I cannot import the diagnostic_updater package in my python code. I have asked the question on my account.

I'm working in c++. If you can, try to work in c++

Moda ( 2014-07-15 02:12:09 -0500 )edit

I have some nodes or drivers that run in python. What do I do with them?

goshawk ( 2014-07-15 09:32:31 -0500 )edit

@goshawk - please ask a new question with more specifics.

ahendrix ( 2014-07-16 14:09:10 -0500 )edit

I got it to work by adding packages from source.
