I am trying to run the ros-wrapper for the first time and I get an error after running:

$ roslaunch zed_wrapper zed.launch

The error is:

Silly -- just forgot to do the obvious:
$catkin_make
$source ./devel/setup.bash

Try "rospack find [package]". If that returns an error you may need to source the /devel/setup.bash file of your catkin workspace

I had a similar issue. And rospack did indeed find the file. Any other pointers ?

Hello All,
I tried the solution recommended that resulted in the closing of this topic and it did not work.

I have the following error message.

RLException: [display.launch] is neither a launch file in package [zed_display_rviz] nor is [zed_display_rviz] a launch file name Z
The traceback for the exception was written to the log file

catkin_make ran successfully. I sourced it as recommended.

Thanks

Hi @StairWalkerOne,
If you are using the latest version of the wrapper you must launch display_zed or display_zedm:

I received the same error, but I was wondering if it had anything to do with the fact that I don't have a zed camera operating at the same time I launch the software?
